[00:00:02]Good evening friends. How are you all? I hope everyone is healthy and happy.

[00:00:06]Everyone's preparations must be going well.

[00:00:09]So son, this is our fifth session, sixth session and we are talking about time and work. Okay, right? And this is its sixth session. In this batch we are making you complete the entire arithmetic, son. I am getting the entire arithmetic that we are studying completed for UP Police.

[00:00:25]Ok? And here we are continuously completing it son.

[00:00:28]We would have been taking this live class from 3:00 pm. The session starts at 3:00, son. Okay, right? Yes.

[00:00:33]We start it at 3:00. And son, he is continuously completing it in this batch.

[00:00:37]This is session six of Time and Work.

[00:00:39]After this we will finish the time and work, son. Ok? Today, what we are going to talk about is the base, that is, we are going to talk about wages and about making men, women and children work together. Is it okay son? So let me talk straight to the questions here, son.

[00:00:55]You will understand quickly there. Let me start with the direct questions, son. Okay, right? Come on, everyone, share it once. Son, please share this with all the people who are connected live.

[00:01:04]Then let's start son.

[00:01:08]Everyone please share it, son. Yes, sometimes it happens that the class is not being held.

[00:01:12]The alternate took place the day before yesterday. Now the class was held the day before yesterday, it was not held yesterday, and it is being held again today.

[00:01:17]So there is a little problem. But I am trying not to let all these things happen. It should become habitual like this. We should get into the habit of attending classes regularly. There is no disturbance offline.

[00:01:29]This disturbance is happening regularly online, son. So son, I am trying to ensure that all these things do not happen.

[00:01:33]Come on, son, please share it with everyone. All the people who are connected live, please share this, son. Then let us begin.

[00:01:44]Yes, I am trying son. Ok.

[00:01:46]Radhe-Radhe to all. Radhe-Radhe. Radhe-Radhe brother.

[00:01:51]Come on brother, let's start the session son. Ok? You come straight to the question. Son, the base means the wages that we are paying, son, we are going to talk about that.

[00:01:59]Okay, let me tell you two things first and then you can start. First of all, it will be most important for us, son, that I understand this.

[00:02:08]Son, if we talk about wages, we are talking about the base.

[00:02:12]So wages are always given in proportion to efficiency i.e. work capacity. The work capacity is given in proportion to the work capacity. You have to always keep in mind, son, the wages are given to two or more people, however many people work, whether they work together or men or women, whether men or women and children, all three work in any way, the share of wages among them, the distribution of wages, the share of wages is always given on the basis of their efficiency, on the basis of their working capacity.

[00:02:51]Ok? Hello son. Hello brother. Wages are always paid in proportion to the working capacity.

[00:02:57]You have to keep this in mind. Ok? So the most important thing for us is that whatever be the number of people among us, be it two or four, women, men, children, or anything else, what is their efficiency?

[00:03:09]What is their working capacity among themselves? Meaning how much work is done by them in one unit time? We understand that.

[00:03:15]That is work capacity. So son, if we find out the working capacity then we can distribute wages accordingly. Son, we can distribute wages according to work capacity. Is it okay brother? So if you understand this son, then let's talk directly about the questions.

[00:03:28]Look son, let's start from here. This is our first question, son. A contractor took a contract to build a road in 100 days. Ok? The labourer who is a contractor takes the contract to build the road in 100 days, son.

[00:03:44]Taking contract to build road in 100 days. Okay son? He employed 110 men. After 45 days he found that only 1/4 of the work was completed.

[00:03:56]Ok?

[00:03:59]How many extra men should be employed to complete the work on time? How many extra people should he employ? So that the work gets completed on time, son. Get completed on time. How many more people should he hire? This is the question, son. Hello son.

[00:04:13]hello. hello. Ansh Bhai, hello son. So let us understand here son. Look, the most important thing for us here is that we should understand this, son, when we take up any work on contract, then I should do it in such a way, son, that this is M1, meaning there is man, there is dos and there is hour. Okay son, and here's the work, son. Similarly, there is m2, d2 and s2. mdh/w2 is done. Let's get the work done.

[00:04:44]If you understand this son then there is no problem. This is how we can do it.

[00:04:49]Man days our upon work. Man days our upon work. Let's do it like this. Son, see how? For example, suppose here he has a contract of 100 days, son. Ok? If you employed 110 people, you replaced m with 110 here.

[00:05:05]How many days did you work, son? 45 days. 45 days. Is it okay son? If it's not time then leave it, it's okay.

[00:05:14]How much work did 10 men do in 45 days? One unit out of four 1/4.4s is done son. 1 unit work done.

[00:05:21]Ok? Look ahead, son. Now how many people should be deployed? I do not know.

[00:05:27]What does the work have to do? The work has to be completed on time, son. 45 days of work have been completed. The contract is for 100 days. It's been 45 days, son.

[00:05:34]So 55 days of work remained. 55 days of work left son. Is it okay brother? And how much work is left?

[00:05:41]1/4 out of 4 becomes 1 unit, son. So 3 units of work remained. That's all you had to write. You should have written this much, son. Done. Let me solve this here, son. Look, this is 100.

[00:05:52]This is 45, son. Those three will come here son.

[00:05:55]Get three here and 55 is down, son. Just cut it yourself.

[00:06:02]You will cut it, son.

[00:06:15]So brother, yes, hello, hello son.

[00:06:20]Okay sorry, these 110 people are employed.

[00:06:23]Son, look from here. 110 people are at work, son. These are 110 people, son. There are 110 people here. There are 110 people. Just cancel it, son. This will come subtract 11. It's five. You will cut it by five, son. 5 * 2 = 10. 45 and 90 * 3 = 270. Is it okay son? This became 270. It became 270. So this means you should employ 270 people. You had bet 100. The question is how many additional men should be deployed? And more should be installed. 270 people have to be deployed, son. 110 were already installed. This means you should employ 100-160 people. 160 people should be deployed, son. 160 people should be deployed.

[00:07:00]Yes brother, yes yes sir, 110 is fine. Yes 160 absolutely right son. 160 people should be deployed, son. If you employ 160 people, the work will be done.

[00:07:10]Okay son. Let's do it this way.

[00:07:12]Look ahead, son. Let's talk about this.

[00:07:16]Look next, son.

[00:07:19]Look at the next question, son. The question is, look, a person takes the responsibility to complete a work in 150 days. The work has to be completed in 150 days. Is it okay son? He appointed 200 men. 200 men were deployed.

[00:07:34]After 50 days, son was here for 50 days. After 50 days he found that only 1/4th of the work was done.

[00:07:40]Okay, right? How many extra men should be employed to complete the work on time?

[00:07:45]So now I will tell you that just like MDH is doing, you can do it by writing there, son. I'll do it straight away, son. Look, he employed 200 men. 200 men worked for 50 days. If you worked for 50 days, how much did you work? One part means it has a value of one.

[00:08:00]How much is left now? Three. Brother, 1/4 question, son is saying that if it becomes 1/4 then three are left. Three left. And what is this work to be done? 50 days work is done son. So 100 days left for 100 people. It is a 100 day job. The son did 100 days' work for 50 * 2 = 100. There should be 300 men. There should be 300 men.

[00:08:19]You have deployed 200 people. This means you have to invest Rs 300. So you have to deploy 100 extra people. You have to deploy 100 extra men, son. D is the correct answer. 100 additional people have to be deployed. That's absolutely right, son. The first one is absolutely correct. You are answering correctly son.

[00:08:34]Son, please share it with everyone. Is it okay brother? Share it.

[00:08:39]Share it with everyone, son.

[00:08:44]okay brother. Let's see the next one, son.

[00:08:46]Answer this. Answer this. If anyone has any problem anywhere, son, please comment. I will try to make you understand. Is it okay brother? You just comment. Look, a contractor takes a contract to build a dam in 60 days.

[00:08:58]Starts work with 40 men. But after 40 days he employed 50 more men. 50 men were employed so that the work could be completed on time.

[00:09:07]Ok? If he had not employed extra men, how many days would the work have continued? Is it okay son? If he had not employed these extra 50 men, how many days would the work have continued? Okay, right? This is a very easy question.

[00:09:26]You would have understood this in two ways. Look son, let me tell you about 40 such things. 40 men were deployed. How many days did 40 men work? 40 days. 40 men worked for 40 days. This means that these sons who were made in 1600 were made in 1600. 1600 man days were created. What did he do after this? Added 50 more to 40. That means 90 people were deployed and 90 people were deployed son.

[00:09:53]And look, here 40 men had done it for 40 days, son. How much is left now? 20 days work. 20 days of work was saved. Brother, the contract is not complete, it is only for 60 days, son. 40 men did it for 40 days. Now what did he do after that? I have added 50 more people, son. Total 90 men are working for 20 days.

[00:10:08]This means that 1800 people did this work and thus the work was completed on time. In this way the work was completely completed. So son, how much total work was done? You will say Sir, this is 3400 units of work. There is no problem in this, son, employ 40 people.

[00:10:22]Now 40 men are working for 40 days.

[00:10:24]This means that the work of 1600 people was done.

[00:10:26]After that 50 extra people were added. So 40 and 50 90 men are done. The contract was for 60 days.

[00:10:31]40 days of work has been done, son. So how much is left now? 20 days. 90 men worked for 20 days and the whole work was finished.

[00:10:36]This means how many people will do the entire work? So you will tell you sir, it is the work of 3400 people.

[00:10:42]How many people are responsible for this work, son? There is work for 34 people. Now this is the work of these 34 people, I am writing it here, son. If these 50 people did not do the work of 34 people.

[00:10:55]Only these 40 men do it all the time. Only 40 people would do it, son. So look, four becomes 4 * 8 = 32 son and 4 * 5 = 20 so the work would have continued for 85 days, how many days would the work have continued for 85 days, it means the contract which is of 60 days would have been completed in 85 days, which means the work would have continued for 25 days extra son, 25 days extra, okay, firstly this is the way of the question, you could have understood the question like this, okay son, you could have understood it like this, now secondly see what he has done. You can also understand it like this, son, look, he spent 40 men in 40 days.

[00:11:38]Ok?

[00:11:41]What happened after these 40 days? 40 men and plus 50 men extra and then the work was completed in 20 days. You have to understand this, son. Tell me why this work was completed on time? Why did it end on time? How did this work get completed in 60 days, 40 days and 20 days? Who did the extra work? So you will say Sir, these 50 people had come, these 50 people worked for 20 days.

[00:12:10]That's why the work was done on time. This means that 50 people did it for 20 days, son. If these 50 people had not come, those 50 people would have worked for 20 days.

[00:12:20]If he had not come, who would have done this work?

[00:12:23]These 40 people would do this. Now tell me, if the work of 50 people is done by 40 people, then it means you will have to work for 25 extra days, this is just a simple question, son, only this much had to be solved, brother, 50 people, yes son, 50 people did extra work, right?

[00:12:42]Son, 50 people did unnecessary work, there were not 50, 40 people were employed, along with 40, 50 more extra people came and then the work was finished in 20 days, this means these 50 people worked for 20 days, they got their work done, they got our work finished, so if these 50 people have worked for 20 days, then it means the work of 50 people is of 20 days, if these 50 people had not done the work for 20 days, then the same 40 people would have had to do this work, and if those 40 people had done it, then it would have taken them 25 days, that's it, your D is the correct answer, son, D is the correct answer, okay, if you don't understand then please comment Do it son, if you did not understand then I will try to explain it again.

[00:13:19]Namaste brother, Namaste, Namaste, Namaste, son, if you have any problem then tell me in the comment, son, if you did not understand. Ok? See the next question. Okay, answer this son.

[00:13:33]Wherever you do not understand, please keep commenting, son. Okay, right? Please do like, share and comment. Keep doing this.

[00:13:39]This seems a little better. And you answer. Whether you go wrong or right, it does n't matter son. You just answer that sir yes it will come. Okay, right?

[00:13:49]You might be doing something wrong somewhere. If you are making a mistake, son, if the mistake is explained to you right away, then you will not repeat it again. It is definitely confirmed in you that you should improve on it. It will improve when you are explaining it online in the class. At the same time, your mistake will definitely be corrected. So, keep doing it.

[00:14:05]Okay, see, son, a contractor promises to do the work in 92 days.

[00:14:10]Okay, he employs 100 men.

[00:14:12]After 48 days, he sees that three works have been completed. Look, son, you don't have to do anything, understand it like this. 100-110 men are employed.

[00:14:22]Ok? Work was done for 48 days.

[00:14:26]110 men completed 3 units of work in 48 days.

[00:14:31]3 units worked. Is it okay son? 48 The man should understand this very carefully.

[00:14:36]You don't have to do anything. 110 men were employed. Work was done for 48 days. So how much of the work did these people do? 3/5 means 3 out of 5 units worked. Did three things.

[00:14:49]How much work is left now? 2 units of work left.

[00:14:53]2 units of work left. And then what was to be done?

[00:14:56]How many people can be removed so that the work is completed on time? Son, look, it is a 92 day job. It has been 48 days. It has been 48 days.

[00:15:05]This means son, 44 days of work is left. 44 days of work left. Just see, if 110 people work for 48 days, then three people get three-quarters of the work done.

[00:15:16]Now in this question out of five, son, 3/5 is 3 divided by 5, so if it becomes 3 out of 5, then in how many days will it be left, in 44 days, it is done, son, solve it, you will subtract 100 from 11, son, it becomes 11 * 4 = 44, okay brother, let us subtract it, this becomes 4 * 3 = 12, 12 * 4 = 48, 4 * 2 = 8 * 10, that means 80 men, if 80 men are employed then the work will be done, now tell me son, how many men did he employ, 110 men and now how many men are required to complete this work. The work will be done if you apply 80 rupees.

[00:15:48]So how many people can he remove?

[00:15:51]Remove 30 people. 110 people have been deployed. The work can be done by 80 people. He can remove 30 people.

[00:15:57]30 men can remove it. Don't give me any option, son.

[00:16:00]okay brother. How many will be employed? So you can tell me sir how much it will cost? If put to work it can reach 80. If employed, 80. The question asked was how many people can he remove? I asked, son, how many did you remove? How many should I remove, son? So 110 are installed, 80 are installed.

[00:16:14]This means removing 30 people. Is it okay brother? Son will remove 30. Yes, it is absolutely correct. Well done. okay brother. See next.

[00:16:24]Answer this. Answer the next question, son.

[00:16:28]Answer the next one, son.

[00:16:33]Answer the next one, son. See.

[00:16:37]Next. Look son. 40 men can complete a piece of work in 40 days. Ok? 40 men can do it in 40 days.

[00:16:44]They started together but at the end of every 10th day five persons left the work. In how much time will the work be completed? Five men have to leave the job every 10 days.

[00:16:54]Five men have to leave the job after 10 days.

[00:16:57]Son, please share it with everyone. Keep liking and sharing. If you are new to the channel then please share and subscribe to the channel, son. Okay, right?

[00:17:04]Yes. Share it. This is our regular class at 3:00 pm, son. Okay, right? Every day we start the session at 3:00 pm. Come on son, this is 40 days of work for 40 men.

[00:17:14]40 men work and they do the work in 40 days.

[00:17:19]This means it is the work of 1600 Mendez. Ok? It is important for us that the work is of 1600 people. Okay, right?

[00:17:28]What to do now? But every 10th day five men have to leave the work at the end of the 10th day.

[00:17:34]Look son, 40 men started the work.

[00:17:37]Worked for 10 days. This meant 400 mains were made.

[00:17:44]Mendis means Man Day. 400 mains have been made and we need 1600. Ok? Now what happened son? Out of 40 men, five men left.

[00:17:52]So son, 35 men are left. 35 people did it again for 10 days. This means 350 menus were made, son.

[00:18:00]350 tables were built. After that, 30 five left again, son. These became 300 menus. Then he left, son. 5 This means son, it is 250 minutes. 1600 is the work of Mendez. Take care son, how many tables are there? There are 1600. Make it 20, son. Get it done in 20 to 10 days. This makes 200. Look at this, how much has it become, son? 4 3 7 3 10 2 14 And a 1500 unit job is done. 1500 The work is done son.

[00:18:32]We need 1600. This means son 100 Mendez and left.

[00:18:41]Look son, tell me, are you facing any problem? There is work for 1600 people. 40 men stayed for 10 days, 35 stayed for 10 days, 30 stayed for 10 days, 25 stayed for 10 days, 20 stayed for 10 days. Is it okay son? It became 1500. 100 men survived. Now after this, see how many days have you been here, son? It's been 50 days, son. The work of 1500 people was done in 50 days. Now tell me whose turn is next after 20? So you will say sir now 15 people will work. After 10 days, five more left the son. 15 men will work.

[00:19:14]How much work does 15 men have to do? How much work is left now? 100 days, so if 15 people work on 100 days, son, then it will take 5 * 3 = 15 5 20 100 6 days, 2/3 days, 6 days, 2/3 days. It will take 15 men 6 days exactly 2/3 days to do 100 parts of the work, son. So look here son, how much work has been done? 50 and 6 will become 2/3 correct 56 correct 2/3 B is the correct answer for this son B is the correct answer for this Palak you are telling the right answer son 50 correct sorry 56 correct 2/56 correct 2/3 ok son 56 correct 2/3 will come see the next question it is not easy at all I do not teach in such a way that you just keep passing the time right it will not be so easy that you just keep sitting and passing the time thinking that yes right everything is coming everything is coming.

[00:20:08]Started teaching multiplication. okay brother? You should try a little, son. Try it. If you don't understand anything, please comment. I will try to make you understand. I will try my best to explain it to you.

[00:20:17]okay brother? You must improve. You have come here to learn, son. Ok? Let's see the next one once, son. A contractor undertakes to build a road in 40 days and employs 100 men.

[00:20:29]After 35 days he employed 100 more men so that the work could be completed on time. That's right brother.

[00:20:42]What's the problem with that, brother? 100 men were employed.

[00:20:44]100 men were put to work for 35 days. It's been 35 days. What happened now son? There were 100 men. I invested 100 more. I wrote these and the work was completed in 5 days, son. This was nothing to be done.

[00:21:04]Son, you should have finished it after seeing it like this. It's a 40-day contract, son. 100 men worked for 35 days.

[00:21:10]Ok? what happened after that? If 100 more people were employed, the number became 200. And the work can be completed on time. That means the work was completed in 35 days, five days and 40 days. Now tell me, I was saying if we had not engaged 100 extra men, these 100 extra men, son, look, 100 men are already working, son, 100 men are working, along with 100 we engaged these 100 extra men, only then the work would have been completed, if brother, these 100 men would not have worked for 5 days, they are already doing their own work, 5 days are theirs, 100 men 's extra 5 days' work is theirs, so we got them to do more, got these 100 people to do five days, that is why if these 100 men were not there, then these 100 would have done five more days, I mean, how many more days would the work have continued, five more days would have continued, brother, 100 men are already working, son, 35 days, now 100 men should work for five days, they will definitely do it, but 100 more men came, they got the work completed in 5 days, so if these extra people had not come, son, then these 100 would have had to work for another 5 days, then these 5 days would have been spent by them 100 would have taken 5 more days, yes absolutely right son, okay brother, next look, answer this, son, answer this, look, you try to understand, okay, you read the question, okay, here the calculation, you can speed up the calculation, here I will explain the language, where you can improve it, our job is only to teach you multiplication, division, addition and subtraction, friend, if you have come to learn this then why are you studying, we are learning the language here, son, the language, how to understand this language, what has been said, okay, okay, let's go, yes, all of you please like and share once.

[00:22:51]If you are new to the channel, please share and subscribe. Is it okay brother? If you like the content and understand it, then please do like it, son. Ok? Come on, look at question number seven, son. It is said that 30 men can complete a piece of work in 24 days.

[00:23:05]Ok? 20 people started the work.

[00:23:10]Worked for 12 days. How many more persons will be required to complete the remaining work in 4 days? Well, the remaining work has to be completed in 4 days.

[00:23:17]Look son, there are 30 men. 30 men have 24 days' work.

[00:23:25]So if 30 people work for 24 days, son, then there is 772 units of work. Now it is being said that 20 people out of these started the work and worked for 12 days. Now, son, if you make 20 people work for 12 days, it means you have made 240 units of work. Now you can tell from here sir how much is left? How much work is left?

[00:23:47]So minus here son. You will say Sir, 480 units of work are left. Ok? Now he was saying, if there is any problem here, please tell me son. 30 men can complete 12 pieces of work in 12 days.

[00:23:58]So if 30 people, sorry, work in 24 days, then 24 * 3 = 72 mandates, son. Now 20 men started the work and completed it in 12 days. 20 did it for 12 days, which means 12 * 2 = 240 men did the work, son. How much is left now?

[00:24:11]48 480 units of work left. This remaining work has to be completed in 4 days. If the remaining work has to be completed in 4 days son. To be completed in 4 days. This means you will have to employ 120 people. How many people will be required? 120 people will have to be deployed, son.

[00:24:28]Ok? And how many sons did you plant? 20 men started the work. 20 men started the work. 20 men started the work, son. The work was started by 20 people and 120 people are needed. This means how many additional persons should be deployed and if required, then it means 100 more people are required son. 100 more men are required.

[00:24:50]okay brother. I need 100, son. Then 100 more people should be employed.

[00:24:56]Son, 100 more people should be employed. If you do n't understand anything, tell me. There are 30 men each.

[00:25:02]Work 24 days. There are 720 units of work.

[00:25:06]20 men were employed. 20 men started the work. If done for 12 days then 12 * 2 = 24 means 240 mendays. If 240 out of 720 work is done then how much is left? Remaining son 480 units of work left. Son, you have to finish this 480 unit work in 4 days. 480 to be finished in 4 days. This means you will have to keep 120 people per day. And how many sons did you plant? If you employ only 20 people and you will have to keep 120 per day, then it will be over in 4 days.

[00:25:33]This means, look here son, you will have to employ 100 people, you will have to employ extra people. Is it okay son? Let's see further, son. Look ahead.

[00:25:44]Share it once, son, everyone. Share it brother. This is everyone's responsibility. Yes, those who understand can go. There is no problem. Those who know all these topics, why waste time? You should study somewhere else, son.

[00:25:53]Look, there is no problem. You people who want to stay, those who are watching, son, you can share it.

[00:26:00]Keep sharing brother. Let 20 men 20 men can do 1/3 of the work in 20 days.

[00:26:12]How many people will be required to complete the remaining work in 25 days?

[00:26:16]okay brother. Look, 20 men worked for 20 days.

[00:26:24]1/3 work done. Part one of 3 is done. That means, look, 400 men, 20 men son, worked for 20 days. Look, what is math, if you pay even a little attention son, it gets done immediately. There is nothing in it.

[00:26:39]Look, this question is saying that it is not according to my calculations, son, 20 men can do 1/3 in 20 days. Look, to do 1/3 of the work, 20 men should work for 20 days. Do you know what this means?

[00:26:56]20 men in 20 days means 400 tables were made.

[00:27:01]Son, this is 1 unit work out of three. So do you know how much work was done in 3 units? 1 = 4 so 3 equals you will say sir 1200 units.

[00:27:12]Brother, it is 1/3 work. 20 people should do it for 20 days. So if 20 people work for 20 days, son, then 400 mandates will not be made. 400 man days will not be created.

[00:27:21]20 people are staying every day for 20 days, it means there is work of 400 people, right?

[00:27:26]And this work, this work, how much is son, 1/3? So if this 1/3 out of three, one unit work in 400, then three is 1200, then son, how much is left, sir, 800 units are left, 800 units are left, son, 400 becomes 1200, total is 800, now you have to finish this work in 20-25 days, if you want to finish it in 25 days, son, then how many people are required, then 25 will become 25 * 3 = 75, son, five are left here, 25 * 2 = 50, means you need 32 people, how many do you need, son, you need 32 people, this is the right answer, son, okay, son, yes, absolutely, brother, good afternoon, son, good afternoon, brother Gagan ji, good afternoon, son, let's talk further, you can discuss it in that way. You could have understood it too, son, MDH was telling you, look, you should do it like this here, if anyone faces any problem, the number of people is 20 days, son, then how much work was done here, he said 1/3 of the work was done.

[00:28:22]1/3 of the work is done. Write it like this. Now I don't know how many people there are. In how many days the work has to be completed? Said in 25 days. In 25 days. Is it okay son? Write like this. How much work is left? So one out of 3 is done, so 2 out of 3 is left. Then write it like this. Write it like this: mdh / w mdh / w Is it okay son? Just look here son, this has been cancelled. Will you bring two here? This will become see 20 * 20 * 2 and up will come to 25 ok son it will come to this much just subtract the value of m son five 5 * 4 5 * 4 = 20 5 * 5 = 25 5 * 4 = 20 it becomes son 4 * 4 = 16 * 2 = 32 it comes to this just 32 people should be employed son look at the next let's look at this next question son look at this next question son yes brother share it once son everyone brother keep sharing this should go on regularly son share continuously you mean by sharing you do not see or not see connect with people the students with whom you are sharing may know this you do your work talking or not seeing is a different condition ok brother let's keep doing it son please ok look ahead ok keep studying as well so all this in between like you tell the answer then do it the contractor employed 40 labourers to complete it in 36 days ok brother in 36 days Getting the job done. I put 40. Ok?

[00:29:47]Look son, I have employed 40 labourers. After 20 days he came to know that only 1/2 Bhai Saheb 40 men were working.

[00:29:53]Only half the work has been done in 20 days.

[00:29:56]Only half the work is done. Then half the work has been done in 20 days. That means there are 800 mandates. This is half the work, son. This is 800, son. 40 men worked for 20 days. This is half. So when it's half, that's all that's left.

[00:30:09]And in how many days will this remaining work be completed?

[00:30:13]How many days will it take for the extra labour to be completed on time, son? Now tell me, it has been 20 days.

[00:30:17]How many days' contract is it, son?

[00:30:19]20 days of work out of 36 days has already been completed. So how many days are left? 16 days old. Now 16 days of work is left. This means 50 men are needed. You are investing 40, you need 50. That means you need 10 extra people, son. How many extra men do you need, son? 10 extra men are needed. Tell me son, are you facing any problem anywhere? You tell me. If you don't comment, how will I be able to explain it to you?

[00:30:40]Brother, look, you employed 40 men, the work was done in 20 days, half of it is done, son. Now it is asking how many men are needed and if we hire extra men, then let us employ how many men first so that the work gets completed in 16 days and how much work is there, he says half the work is done, it is finished here, okay, from here if you find the value of m, son, then it will be 40 * 20 / 16, okay brother, subtract this, 4 * 4 = 16, 4 * 5 = 20, son, subtract it from 4, 10 times from 4, this means the value of m has become 50. If you want to finish this work in 16 days then employ 50 people. Then he is asking how many additional labourers should be employed. I have to tell you about the extra ones. How many should I apply? It is 50. How many extras should you put in?

[00:31:24]You were betting 40, you should bet 50. Means 10 extra. 10 extra, understand this extra term son. You have to tell me how much extra you want to spend.

[00:31:30]Okay, right?

[00:31:32]Tell him if you want to pay extra, son.

[00:31:35]Tell me the extra ones. Okay, right? There are 50 to be installed. If you think there are 40 then how many?

[00:31:39]10. Additional Imposition Is it okay son?

[00:31:41]See next. See next. Question number 10.

[00:31:44]Answer it. Wherever you do not understand, please answer, son. Everyone please answer brother. Ok? Answer me son. 12 men can build a wall in 8 days. If the work is to be completed in 6 days, then how much y? Look, son, 12 men take 8 days. The work has to be completed in 6 days. To be completed in 6 days. If you want to finish it in 6 days then employ 16 people. That's what we're doing. I am doing the same thing in those questions too, son. 12 men do it in 8 days. So this means 12 * 8 = 96 96 times. If 12 men finish it in 8 days. So 12 12 means 12 * 8 = 96 minutes, son. It took 96 men in 8 days. So there are 12 * 8 = 96 menj. Now if you have to spend this 96 days on six people then you will have to spend 16 days. 6 16 * 6 = 96 Son, you will have to work for 16 days. Ok? Well, how many people will be required? So you will have to employ 16 people for six days.

[00:32:42]Apply more and it will be finished in six days. Is it okay son?

[00:32:48]Let's answer the next question.

[00:32:55]Ok? Come on son, let's talk further.

[00:32:57]27 days' food supplies for 500 soldiers in a military camp.

[00:33:00]Look son, there are 500 soldiers. Have to eat for 27 days. There is food for 27 days for 500 soldiers. Is it okay son? He was saying that after 3 days 300 more soldiers arrived.

[00:33:13]Well, after 3 days, 500 people, this means that son, 500 people must have eaten for at least 3 days.

[00:33:24]Food for 500 people for 27 days, son.

[00:33:26]Suppose the food starts from today. Now if 300 more people come after 3 days, it means that if 300 people come after 3 days, then 500 people have already eaten for 3 days.

[00:33:35]So, son, if 500 people ate for 3 days, then there would be food left for 24 days for all 500 people. Are you okay now, son? There must be food left for 500 people for 24 days, son. Ok? Now whom do you want to feed this food? He said 300 more people have come. So earlier there were 500, now it has become 800 son. I have to feed 800 people, son.

[00:34:01]800 have to be fed. 8 * 3 = 24. 5 * 3 = 15 days. Your answer will last for 15 days. Yes.

[00:34:07]Yes. Palak is right son. You have told it absolutely correctly. Then we will eat, son. How many days? It will last for 15 days. The food will last for 15 days, son. That's the only question. 15 Look son, 500 people will eat for 27 days. 500 people ate in 3 days. So now there is food left for 500 people for 24 days. Now the food for 500 people for 24 days will not be eaten by 500 but by 800 people. Son, if you feed 800 people food worth Rs 500 for 24 days, then it will last only for 15 days. It will last for 15 days. Is it okay son? Okay, it will last for 15 days. You guys answer brother. You are answering very slowly, friend. Isn't it? I am teaching them very comfortably, I mean, so easily, yet they answer very little. Keep answering son. Let's talk further here son. Look ahead, son. 80 men work for 6 hours a day. There are 80 men, son. Work for 6 hours.

[00:35:07]80 men work 6 hours a day to complete the work in 15 days. The entire work is completed in 15 days.

[00:35:13]Ok?

[00:35:15]Okay son, 80 men, come on son, look, let's write it here, son, there are 80 men, they work for 6 hours a day, they complete the entire work in 15 days, further he is saying that this work has to be completed in 10 days, this is the work, son, this is the work, I don't know how many men, I know the work. Well sorry man I know. 45 men are working. o Get 45 men working. Get the work done in 10 days.

[00:35:53]How many hours per day will it be? It's done son. This was what had to be done. 80 men work six hours a day. The work that is done in 45 days, get it done by 45 people in 10 days. Tell me how many hours should I work per day? How many hours to work? Just do n't do anything son. Done. Look, finish this from here son. No problem 15 * 3 = 45 that's it. Three becomes 3 * 2 = 6. 8 * 2 = 16. 8 * 2 = 16 It's here son.

[00:36:23]Ok? Any problem son? Subtracting 15 from 15 becomes 15 * 3 = 45 3 * 2 = 6 son. The bus will arrive in 8 * 2 = 16 hours. 16 will come. D will be the correct answer son. 16 should come. You should work 16 hours a day, son.

[00:36:38]Good afternoon son. Good afternoon. Good afternoon brother. Yes. Good afternoon.

[00:36:46]Good afternoon son. Come on, answer it son.

[00:36:49]Answer it. Everyone please answer.

[00:36:51]Look son, are you facing any problem somewhere and are not able to understand, please tell me. If you are not able to understand, please tell me.

[00:36:56]You just tell me the truth. Sir, if you are not able to understand then I will try brother. There is no problem in this.

[00:37:00]Look, this question is saying, son, if 80 people work for 6 hours, it will be done in 15 days.

[00:37:06]Now this work, this work has to be done by 45 people in 10 days. So tell me how many hours should one work? Now you just need the value of h here, son. So this 80 * 6 * 15 and this value came here son. 45 * 10 We just subtracted zero from zero.

[00:37:28]15 * 3 = 45. 3 * 2 = 6, son. 8 * 2 = 16. It just arrived. Okay, you must have understood. Look ahead, son. Now let us start with veg. Let's talk about wages. Okay, right?

[00:37:40]How much will each person's wages be? Yes. How much will each person's wages be? Let's talk about that. Let's talk about wages, son. Look carefully here. Ok? This is now the first question of Waze. I am asking you the first question on wages, son. A B can do a piece of work in 10 and 15 days.

[00:37:54]He gets a wage of ₹6000.

[00:37:56]So tell me what is A's wage? Is it okay son? I have already explained to you about wages.

[00:38:00]Son, wages are always distributed based on their efficiency. So A is son A does it in 10 days. B is the son. B does the work in 15 days. I took the LCM, son. 30 has arrived. Son, their efficiency became three and his became two. Now just see son, if they get 3 units for Rs. then they will get two. If this is the efficiency ratio then what is the total, son? What is the wage in five total questions? 6000 5 is equal to 6000 son so 1 is equal to 12 * 5 = 60 right?

[00:38:31]120 No problem son, it has become ₹1200. Whom did you ask son? What is the share of A?

[00:38:36]I asked you the value of three units. Tell me three equals. I will make it 3 * 1200, son. So this comes to ₹600.

[00:38:41]How many are there, son? 3600 answers have been given. B will be the correct answer. You always have to keep wages in mind, son, how is the wages distributed? Based on their efficiency, based on their capacity. It is not necessary, son, that you write from here. You can also write like this from here. If you are understanding it like this then son, understand it like this. Now it is there son, I have given you their time. It does this in 10 days.

[00:39:04]It does this in 15 days. If you cut it, son, it does it in 2 days. Does it in 3 days.

[00:39:09]This is Efficient, now if we calculate the efficiency from here, its working capacity will be three, son.

[00:39:13]It will have two. So money is always distributed as wages. Wages always increase, son, always in proportion to working capacity.

[00:39:20]in proportion to the working capacity. Is it okay son? So it has three. He has two, son. So what is the total here? Five.

[00:39:26]What is the total wage in question? 6000. If the value of 5 units is 6000, son, then you had to tell the value of 3 units. The value of three had to be told. It's 3600, son. Okay, right? Let's ask the next question.

[00:39:37]Tell me this.

[00:39:39]Tell me next, son. Yes. Well done. Everyone should tell the truth. Ok? Bhavna Palak Diksha. Ok? Yes. See the next one, son. A, B and C can do a piece of work in 6 8 12 days respectively. Is it okay son? See. A does it in 6 days, B does it in 8 days and C does it in 12 days. Son, I took LCM from here, son it became 24.

[00:40:04]Look at its efficiency from here, son, its efficiency has become four. This one got three and this one got two. Ok? What is the total?

[00:40:11]4 3 7 2 became 9. The total efficiency is nine. Is it okay son? Now watch them work together and earn ₹1350. What is the share of B? There is nothing to do, son. Look what is the total efficiency here? nine.

[00:40:27]What is B's share out of nine? B's share out of nine is three. If B's ​​share is three out of nine then the wages are Rs 1300/- Rs 1350, son. Just make it one-third of this, son. Cut it by three. 3 * 4 = 12 3 * 5 = 15 0 ₹450. Is it okay son? Correct.

[00:40:42]A Answer A is the correct answer to this, son. We are right. ₹450 son. How much will it cost? It will cost ₹450.

[00:40:50]Okay son, it will come to 450, very good, everyone told correctly, yes, okay, it will come to ₹450, okay, hey brother, here we will take this in four, this three, this two, so the total is 4 3 7 2 9, son, now the total here is how much, 1350, so son, what is the value of one unit, it is 150, I asked you, B has three units, right son, so if you do 150 * 3, it will come to 450 only, I told you from here, son, this is the thing, this is three out of 9, this is the total nine, right son? Ok. Look next. Answer this son.

[00:41:25]Look next, son. Answer this. Yes.

[00:41:28]okay brother. Ok. Ok.

[00:41:31]Anjali is right. Come on, look ahead, son. A can do the work in 12 days. Whereas B can do it in 15 days.

[00:41:36]With the help of C he completes the work in 5 days.

[00:41:38]Okay, let's see. A Answer me son. A does the work in 12 days.

[00:41:45]A does the work in 12 days, son.

[00:41:56]Ok? A does the work in 12 days, son. Does it in 12 days. B works.

[00:42:05]A does it in 12 days. B does the work in 15 days son. And if C is found by combining A B C then it is finished in 5 days. It's done son. Now look at their efficiency.

[00:42:17]Look at the potential. Answer everyone, son. Okay, well done, answer it, it will be done son.

[00:42:24]Look, if you see from here, son, find out their efficiency. This is 60, the car is 60, son, what will be the capacity, this one is five, this one is four and this one is 12. Now look, son, tell me the efficiency of C from here.

[00:42:40]Son, look at C, how much is A's five, how much is B's four and how much is A, B, C's three, 12. Now, five and four from 12, what is nine? So, subtract nine of A, B, from 12, three of C is left. It's done son. C has three. What were you supposed to do now? C's wages had to be reported. See what the total is? The total efficiency is beta 12. You could have written it like this.

[00:43:01]Total 12 = 960 Value of 12 Total wages 960 12 = 960 So 1 unit costs 12 * 8 = 96 ₹80 If the value of one unit is required to be 80 C. A value of three units is required. You need the value of three, son. You will make it 80 * 3. Make it 80 * 3, son, it becomes 240. It became 240. Okay son. Yes, there are 240 answers.

[00:43:22]Correct. Well done. Yes, everyone is telling the truth. Bhavana Deeksha Anjali Palak tell me the right thing, all of you tell me the right thing. The line is fine. Come on, now you could have understood this thing from here also, son. All these big calculations do not have to be written. Why do I need to write? Isn't it brother? Could have finished it quickly. Look, what is the total efficiency, son?

[00:43:40]What is the total capacity? So the total is 12. How much of 12 is C's? Three out of 12. If there are three out of 12 then you have to divide this into 960, son. Look, cut it out, son. It was cut in four times.

[00:43:50]Cut it by four, son. 24 * 4 = 96.

[00:43:52]240 answers done. Okay, right? A is the correct answer. Okay, right? A is the correct answer. very good. Let's look at the next question, son. Look here.

[00:44:02]A man and a boy together earn ₹800 in 5 days. A man and a boy together earn ₹800 in 5 days. You do one job and earn ₹800 for it. okay brother?

[00:44:13]Earn ₹800. Correct? The work of a man is three times that of a boy. You have given good efficiency son. Their working capacity has been given to them. A man is three times more efficient than a boy.

[00:44:26]Ok. I need the boy's daily wages.

[00:44:29]Boy 1 day means daily in per day. Son, tell me your daily wages.

[00:44:34]Tell me the boy's wages for one day. Look son, I am writing here. Like this is a man and this is a boy.

[00:44:45]Tell me their efficiency, son. Tell me the capacity.

[00:44:49]Tell me the capacity. So this was the question, son, this thing was given in the question that the male capacity of a boy is three times that of a boy. This is efficiency. The man will get three times the money as the boy, son. Ok? Now see how much money you have son? 800. And for how many days is this ₹800? So you will say Sir, ₹800 is for 5 days and you asked us what is it? They have asked us about our daily wages. I have asked for one day only.

[00:45:16]If you get ₹800 in 5 days, son, does that mean how many you will get per day?

[00:45:21]You will say Sir, ₹800 in 5 days, then it means you are getting ₹160 in 1 day. I am getting 160 in 1 day. Now tell me, look at the potential. Three of this one of this what is the total? Four. How much money is there in total here, son?

[00:45:35]1 day is 160 ÷ 4 = 160. 4 * 4 = 16.

[00:45:39]So the boy must be getting ₹40 per day. The boy must be getting ₹40 per day. The boy's daily wages were asked. It won't be 400, friend. I wrote it wrong brother. Day will be at ₹40.

[00:45:50]okay brother. This should have come for ₹40. It should have been 40, my brother.

[00:45:57]No problem. I wrote the option wrong brother. This will not be 400. It will be ₹40 brother. Ok? The boy will get 40 rupees every day, son. 40 will be available daily. He will get 4 * 3 = 12 i.e. ₹120 daily.

[00:46:12]Its 120 its 40 okay son.

[00:46:15]Days will be available at ₹160. ₹800 will be made in 5 days. Is it okay son? You must have understood? Yes. Ok. Do you understand, son? Are you understanding this? Why did you write ₹800 as 160, son? ₹800 is for 5 days, right? This is the wages of both of them. I converted both of them into one day's wages. Five divided by five. Earns ₹160 a day.

[00:46:34]Ok? Look ahead, son.

[00:46:36]See the next question. Answer this.

[00:46:39]Look next, son. Answer this. All the questions are very good. Just use your brain a little bit. A, B, C are engaged to repair a car for ₹575.

[00:46:47]A and C completed 19/23 of the work. Look son, these two are A and C. They completed 19/23 of the work, 19 out of 23.

[00:46:59]So tell me brother, how much did these people leave for B?

[00:47:04]Son, I have done 19 out of 23, so I left four.

[00:47:06]Left four out of 23 for B.

[00:47:10]Four out of 23 Part B did just that. Now how much salary is received for the entire work? 576 How much does this mean and how much does it work? 23 is 576 for 23, son. Sorry it's 575. That means 23 * 2 = 46 son. And 23 * 5 = 25 times, son. So you multiply it by 25, son.

[00:47:31]Multiply it by 25. This means B will get ₹100. B will get ₹100. Is it okay son? B will get ₹100. Total work is 23 units, right son? 23 = 576 575 Sorry. 23 = 575. If 23 is equal to 575. So how many units does B have to B? If you work 4 units, you will get ₹100 for each unit. okay brother?

[00:47:55]Son, you should get ₹100 for four.

[00:47:56]Let me know if there is any problem. Brother, you have done 19th part of the work out of 23, then only 24th part of 23 is left, this is what I have to do and I have to do 4th part of the work out of 23, whereas how much is the wages son, 575, 575, subtract it from 23, son, like this it is deducted in 25 times, 2500 will get ₹100, ₹100, this is the question friend, it is not very difficult son, it just depends on you how you are able to understand it, is it okay, let's see the next one son, see this, tell this to this son.

[00:48:31]Tell me this.

[00:48:33]Yes. Answer me son. Watch four men four boys earn ₹21 in 7 days. 11 men and 13 boys earn ₹8320 in 8 days.

[00:48:46]How much money will a man and a boy earn respectively? This has to be told. Okay, fine brother. Look son, I am writing here. These three men, four boys, four boys, three men, four boys, look son, we need the account of one day, how much will one man, one boy earn, how much will one man, one boy earn in one day, this has to be told. Now look son, if he earns ₹2100 in 7 days, then he will earn ₹300 in 1 day.

[00:49:30]Ok? Okay son. 2100 in 7 days son, then it becomes 300 in 1 day.

[00:49:36]300 in 1 day of three men and four boys. Ok? Come here now, son. 11 men and 13 boys earn this in 8 days, son. 8320 so in 1 day you will earn 8*1808*4 = 3240.

[00:49:53]Earn 40 in 1 day. Is it okay son?

[00:49:56]Earn 40 in 1 day. Just what do you have to do now? Be it a man or a woman, give the same to anyone and give it to your children. So I am doing one thing. Let me multiply it by 11 here, son.

[00:50:06]I am doing these three here.

[00:50:08]11 is multiplied above. Reduce it to three.

[00:50:10]I will write it here. Let me write it here, son. Look, this will become 33m + 44b = 3300. Is it okay son? It has become equal to 3300 and do it like this here son, 33 is equal to 39b and this will become equal to 3000 120, okay son, see from here son, this will end.

[00:50:39]Anyone have any problems? This has been cancelled son. Five left here 5b How much will be left here son? 180 180, so this means the value of B has become 36, son. B's money became Rs 36. 5 If the value of B is 180 then B gets 36, which means this option will be correct. Then B gets 36. It's done son. B earns Rs 36 per day. How much does your son earn? Earns 36. Now see, you can try it if you want, son. This is 3m.

[00:51:14]How much is 3m + B? 4 4 * 36 = 300 Okay son, so look at the value of 3m here, 300, this becomes 36 * 4 = 144, you will subtract it son, 180 is left, divide it by three, 180 sorry, 156 is left son, this becomes 144, right son, you will subtract it here, 156 will be left, just subtract it by three, son, 3 * 5 = 15, 3 * 2 = 6, son, the value of m becomes m = 52, son. So this option is correct for them. That's right son. Okay, right? 52 36 State the feeling correctly.

[00:51:53]52 and 52 and 36. Ok? Let's look at the next one.

[00:52:00]Look ahead, son. If you are able to understand this question.

[00:52:03]See, if five men and eight women can do a piece of work in 12 days and they get a total wage of ₹1320, then how much can two men and four women get?

[00:52:14]Okay, son, look at this thing. If this question arises here then you will not be able to do it.

[00:52:19]What to do here? I will do it. I will fix it son. Look, let me fix it.

[00:52:24]This should not happen here anymore. And it is written wrong. And it shouldn't happen anymore. Would it have been here or now, tell me son. Now it is correct. Now tell me.

[00:52:40]Okay, right? He wrote it wrong. look son. Now I want to tell you that five men or eight women can do a work in 12 days.

[00:52:48]Meaning, five men should do it or eight women should do it.

[00:52:52]So this means son, you have to do the same work from here.

[00:52:54]We always have to distribute money according to capacity. It has to be distributed according to efficiency.

[00:52:59]So convert it into efficiency like this, son.

[00:53:01]Look, there are five men and eight women. Sorry there are eight women. Ok? This means that the efficiency of man and woman has become 8:5, son. If there is any problem with efficiency, please let me know. 8:5 is their capacity. The men's capacity is eight. Five of the women. It's done.

[00:53:27]One man does 8 units of work. A woman does 5 units of work. The total became 13 units.

[00:53:31]Total is 13 son.

[00:53:34]You have to distribute the money in this ratio. The money has to be distributed in this ratio, son. Now see, he has given you this wage, it is the wage for 12 days, son 1300 1320, if someone earns ₹1320 in 12 days, it means son, he will earn ₹100 110 per day, you are wrong brother, does he earn ₹1320 in 12 days.

[00:54:18]Look, this boy has memorized it, he has fixed it ₹720, hey Diksha offline class, if we check the value, we will check it, Maharaj, we are keeping this much in mind, here this value is not right, son, let me change this value, no problem, change the money at this place, son, change the money at this place. I am writing the amount here, son. Come on, you write it here.

[00:55:01]Come on, make it ₹3120 here, son. It's fine now.

[00:55:05]Change the money here, son. Change the money.

[00:55:07]He has a fix. You already know that, right?

[00:55:09]This question was told in the offline class, so he answered it directly. So it's ₹720.

[00:55:13]Now understand yourself where did you get 720 from? I understood that it said 3120 there. Come on, look here 1300 3100, son, is this actually it?

[00:55:23]Here you have to understand that the amount here is Rs.

[00:55:25]3120, son. Now if the wages for 12 days are ₹3120, son, then how much will be left for 1 day's wages? How much will be saved in 1 day's wages? So it will be 12 * 2 = 24 son. 7 * 12 * 6 = 72. 1 day's wage is ₹260. Now if the daily wage is Rs 260, son, then compare it here.

[00:55:43]Compare 260 here, son. This means it is 20 times. So this means you will earn 20 times the wages of a man, son. A man gets ₹160 and a woman gets ₹100. It's done, son. A woman gets ₹100 and a man gets ₹160.

[00:56:00]Now the question was, there are not one woman but two men, son. So how much would the two men have got? So you will say Sir, these 320 must have been found.

[00:56:07]Four women, so how much did the four women get? A woman gets 100.

[00:56:11]Four got 400. How much did you get by combining both? ₹720 son, I got ₹720. Got ₹720. Is it okay son? The answer will be ₹720 when it is ₹3120. Is it okay son? It became ₹720. If there is any problem, please tell me. It's ₹3120 son. The wages for 12 days here are ₹3120. Ok? So if you earn ₹3120 in 12 days son, then you are earning ₹260 per day. ₹260 per day. Now tell me its capacity is 8 units, five its total is 13. 13 = 260 son, so 5 = 100 and 8 = 160, he will get 160 in a day.

[00:56:46]He gets 100. Now there are two men, a son, and four women. A woman gets 100. Four got 400. A man gets 160. Two got 320.

[00:56:58]Son, what is the total wages of everyone together? It became 720. It became 720. okay brother? Okay, now you understand? Everyone must have understood, son. Ok? Just keep it here. There's probably no more beyond this. Yes, that's my only question, son. Okay, right? So how did you like our time and work? Please comment. Please comment after the session also.
