The train chapter in mathematics is based on the fundamental concepts of time, speed, and distance. When solving train crossing problems, the distance covered depends on what the train is crossing: if crossing a small object like a pillar, pole, man, or tree, the distance equals only the train's length (L); if crossing a large object like a platform, tunnel, or bridge, the distance equals the train's length plus the object's length (L + X). Relative velocity is calculated by subtracting speeds when trains move in the same direction and adding speeds when moving in opposite directions. The basic formula is Distance = Speed × Time, with unit conversions between km/h and m/s using factors of 5/18 and 18/5 respectively.

Class 1 ||Trains|| Jharkhand BSc ,ANM_GNM, Paramedical Nursing Entrance Exam 2026Added:
Hello everyone, good evening talk.
Come on, come live quickly.
Today, the maths chapter, the train chapter of mathematics is left and there is a board and stream chapter, after that your course will be over, after that we will work on previous year questions, after that we will work on previous year questions, okay, so what we are going to tell in today's class is trends, everyone go live quickly.
Many people have also joined the app.
So today we will tell you about trains because a lot of questions have been asked about this train in 2025.
Which chapters were taught before this? Which chapters were taught before this? g time, speed, and distance. This chapter was taught.
In this concept, this entire chapter on train is based on this concept.
Ok? The entire train chapter is based on this concept. The questions will be made on the basis of that for the candidates, right? If you have read the chapter on time, speed and distance well, you will be able to do it on the train. You know, like from this chapter, which means train, combining these three chapters, time speed and distance train and your board and state, about eight to nine questions were asked, when in 2025, how much in 2025, you might have seen all these questions, you might not see them this year, but still we have to read them, all the paid candidates will join YouTube because those who can view comments at one place will now join the app as well, then there will be a problem from there, it will become impossible to view comments there.
Ok? You are looking at the comments in one place.
Correct?
So let's start the class.
Look, you guys should make more of this because you guys have been taught these chapters. Time, speed and distance, whatever you have studied, all of you paid students.
Yes, all the paid students are educated. Ok?
So the question will be formed on this basis. There are some bare basic concepts which I am reminding you again. Like do you know what the formula was? If we calculate the formula for distance, what would distance equal? What was the distance distance equal to? G move * time. What? move * time. Isn't that it? move * time. This is what we have read. Distance Equ Speed * Time. This is what I have read. Correct?
We had studied this basic one. What else was there? And we talked about relative velocity.
What happens in relative velocity? Like see two trains condition one is case one, right? Case One and here we take Case Two. Ok? Let's take case two here. See what is there in case one? Suppose that a train is passing by here. This is Train One.
Suppose a train is passing by here. And another train is also going this way. It is going in the same direction. Ok? That the two trains are going in the same direction and there was a condition that one train will go from this side and the other will come in the opposite direction. Meaning both will come and go together.
Both trains are Train A Train B right?
We make it A. If we see the speed of both, then let us assume the speed of the train to be S1, its speed to be S2, whatever is given, in this case its speed is also S1 and its speed is also S2, when there are two such conditions, then the relative velocity was told to you, what will be the relative speed of both? What is relative velocity?
What happened in this case? Relative speed is called velocity, sorry, we will call it speed.
Ok? So what is the speed, which is the relative speed, what will be the difference between the two, the difference between the two means we will subtract from whichever is bigger, whether s2 is bigger or s1 is bigger, we will subtract from that, okay it is not necessary, so for now let us assume that s2 is bigger, in this way we can do it, if s1 is bigger then we will subtract from that, we will not see minus plus here, okay, that means here we can write that s1 is greater than sorry, s2 is greater than s1. That's why we are doing this. Ok? For this condition, the difference in relative velocity between the two will be what happens if both are moving in the same direction, i.e. in opposite directions? What will be the relative speed?
What will be the relative speed? Both will be added. Both of them get connected.
Correct? You had told me about these conditions. I told you, right?
This is basically used in trains.
Correct? In train, yes this is basically used in train.
Now see what is the next concept.
What is the next concept? See what's in the next concept? Are you guys able to understand this? We will ask questions after the next concept. Questions also have to be made. The next question we have is that brother, see, when the train moves, it crosses many things.
Even if it's a tunnel.
Hey, where will I fill up the form now? There is still time brother. Where will the form be filled up now? If he has said so, then it can go till August.
Even the Polytechnic form is still pending.
Understood Kolha, Sonali, why have you guys come to the app? Why aren't you all going to YouTube? Yes. He said to watch it on YouTube.
Ok, good. There is no problem if you are watching here also.
Look here also.
What is Next Concept? Suppose in this also case one case two see what is there in case one? See. Suppose that this is a train. Ok? This is a train. Suppose it is a train. Isn't it? This train will have some length of its own. There will be some length. Isn't it? So see what is there in the case of the train?
This length is what we consider as distance, this is a train. Suppose this is a train. Ok? This is a train.
Suppose that this is a train. Ok? Is this some train? The train is long. Bogie remains. Ok? By doing this the bogey remains. Isn't it? So this is how a train works. Suppose they are connected to each other. Whatever it is, right?
So the train has some length of its own, so the distance covered by the train is the same. There is no special distance here, just the length of the train. The length of the train is called distance. This is the distance, it is the length of the train, right?
So let us understand this length case by case.
See what's number one? If suppose when the train crosses, suppose a bridge will be crossed.
Someone will cross the man. Someone will cross the tunnel. Isn't it? Someone will cross the bridge. In this way, one will overcome various things.
So what is the condition? This is something to note a little. Suppose there is a pillar. There is a pillar. Isn't it a pillar? Pillar. Do you understand the pillar? It must be some pole-wool or consider it a pole. Isn't it? Is it something or is it a man?
What is? There is a man. There is a man. Which is a small thing whose length you can ignore. Compared to the train.
That train is very big. You understand the length of a man and the length of a train, right? Someone has become a pole, someone has become a man, right? Or else it is a tree, tree means a tree, any small thing, a bird, a single bird is crossing, anything like this, if the train crosses all these things, if the train crosses, then note it down and write it down, understood this is important, note it down and write it here, it is okay, this point, if suppose a pillar, a pole, a man, a tree, that means if someone is parking the smallest thing, a train, the train has its own length. I mean the length of the train. So that train, that train, that train, that train, that train crosses its own length, that is, its own length. Meaning, it crosses its own length.
Understand the matter, understand it carefully. Isn't it? Look, if a pillar, a pole, a man or a tree, let's say it is a small thing. If there is a bird, the train will cross its own length. Guess what is the length of the train? l is. So he will cross his own length.
But brother, note two, please pay attention to this point here.
Suppose a train is crossing a platform. What is? Some platform platforms are big. Isn't it? If someone is crossing the platform or crossing a tunnel. Is n't it a tunnel? The tunnel is crossing a tunnel or a bridge. The bridge is also long. Is n't it a bridge? So suppose someone is crossing a platform, a tunnel, some long thing, some cave, then that cave has its own length.
So I am assuming here that what is the length of the train? The length of the train. What should we consider the length of the train? Length. What should we consider the length of the train? L means. Ok? Length of the train.
Hey, you all watch it on YouTube.
Why have you come here in the app? Let the length of the train be l and see the platform is bigger. The tunnel is big, the bridge is big, they will also have their own length. So suppose it is a platform or a tunnel or a bridge, whatever it may be, brother, let us assume it to be any one of these three, let us assume it to be the platform or the bridge, that means the length of the bridge, the length of the bridge, if we assume the length of the bridge, let us assume it to be x. So the distance, the total distance covered, both those distances will be added. The length of the train plus the length of the bridge, tunnel or platform will be added.
That's it, there's just a slight difference.
Meaning this is something to find the distance. Case number one: If a train crosses even the smallest thing like a pillar, a man, a tree etc., then the train crosses only its own length. So whatever the distance will be at that time, whatever the distance will be, whatever the length of the train will be, that will be the distance.
Understand? This is the point.
Suppose a platform, tunnel, bridge etc. is crossing any big thing then what will happen in that case? The train is crossing its length.
Along with this, the length of the platform and tunnel is also added to it.
So this is the total distance. Is this concept clear? So everyone please say yes.
If the concept is clear then you will see that it will go into the same concept. The same one at the back.
So by train because a lot of questions have been asked. That's why I will have to tell you a little about it. That was all there was and nothing else. These were the only two concepts. This concept, you already know what it is.
This condition has already been explained in time, speed and distance.
And you guys already know this about your going. Isn't it? Ok?
But the time, speed, distance is correct for what I have read. And for those who haven't read it, it's a bit confusing. So let's start the question. First of all, let us look at the most basic questions. So the first question is about the speed of a train. The speed of the train is in kilometers per hour.
Look, I had told you about one conversion. Let me tell you one more thing. You will get stuck in the conversion.
See if it is kilometers per hour.
Kilometers per hour. This is a big unit.
If we convert this into meters per second, then whom did we ask to multiply?
We were asked to multiply by 5/18. Yes or no, see, he asked you to multiply this.
When converting kilometers into meters, meters per second, this condition has already been explained.
Still, know it once because it will be useful now. Let's say seconds per meter.
What do you want to change it into?
In kilometers per hour. In which? In kilometers per hour. It happens a little quickly. It would have been a little early. So what will happen?
You will multiply by 18/5. Ok? We will multiply by 18/5.
Understood? These are the conditions. Correct?
Sir, please tell me once more. Hey, nothing, you will understand everything now, just look at the example.
A train whose speed is this much kilometer crosses a platform 200 meters long in 22 seconds. What is the length of the train? See who he's crossing now?
Crossing the platform. Let me explain this one.
Although you will make it but concept is the power. So you have must learn the concept first and you can easily solve the questions. That means, somewhere you should know the basics of the question before solving it.
Once you know the basics, it will happen obviously. Many people here prepare for competitions, so all these things will seem easy to them. Ok? So a train that has speed. Suppose there is a train. Now we will not write that much. Suppose there is a train.
Suppose we make the train do this. Let's do it like this. There is a train. Let's say whatever is the number of land. You will ask how is the train sir? Well, this is the train I guess. Suppose that is like a wire. So let's say the train has some length. Let L be the length. Ok? This will be the length of the train L. He is talking about this length, please find it and tell me. Now look what is there here? This is in meters. This is in meters. The option given also says that the speed is given in meters and how is it given here? In kilometers. So cross the platform. So what will we write as the distance to the platform? Tell me what will be the distance? What will the distance be equal to, sir? What will the distance be equal to? Now I will tell you that when the platform crosses the bridge or the tunnel, then the distance that is covered, the distance that is travelled, the distance that is covered, do you understand? Whose distance is travelled? The train's own length plus the length of the platform. So let's say the length of the train here is l and the length of the platform is 200 meters. Won't you do this, sir? It is 200 meters. It is 200 meters. Well, this is one thing that happened. But what is there here is that there is a train whose speed is so many kilometers per hour. Ok? Velocity speed is also given. Speed is also given.
What is the speed of the train? The speed is given as 72 km/h because this is also in meters. This is also in seconds and this is also an option in meters. So that means it will have to be changed. How much will you do it for?
We will multiply by 5/18. This will go four times.
So somewhere this 20 will become what? Will there be seconds on the meter or not? 20 meters per second. A train whose speed is 72 km. But the hour crosses a platform of length 200 metres in 22 seconds. Then what is the length of the train? Ok. So now we know one thing. What do you know, sir? We know the formula. What do you know about the formula, sir? What is our distance equal to? Speed * Time. Yes or no. We do n't know this. So we will write the same.
Distance Gul Speed * Time. It's done.
What is the distance now? l + 200 is l + 200. Yes or no? What is the speed here? It is 20. Yes or no? 20 came out here in four times 4 * 5 = 20, okay, what is the time 22 seconds, no problem, just this has to be done, this has to be taken out, this will go here, if we multiply it then it will be 440, so it is equal to this, it will become 440 and minus this 200 will go there, then what will be the result after subtracting 200, yes 240 meters, so that means option B will be our option, which will be the length of the train, that is 240, got it, did you understand, a very big question has been asked from this. Isn't it? So don't take this lightly. Isn't it? That I have asked you people a question.
Now you will see many questions and you will solve them easily. Correct? So, I have explained to you whatever I had to explain.
But look, we do n't do that much reading and writing. We have to solve it.
We will do whatever we do in standard way.
But after looking at the question, this is what we will do, there is so much in the question that you can print at home if you wish, then you can print it, what we do is because we know that it is called platform, so we directly know that distance = speed * time, distance = speed * time, so instead of distance we will write directly, we will not do that much, l + 200 will do this directly, okay, here the speed is given, that means speed, here we will do the formula, like this, if you want to write it once, then you will write speed * time, here we will write distance directly, to explain you, we have told you that much, length * time and you will write it directly, here it is 72 72, so everything has to be converted into seconds, so 5 / 18 will be written directly here, after that we will multiply 22 seconds, in this way, by reading the question in one line, what will happen from this, it will save your time, but right now you are learning, so for this you will have to explain things in detail so that your understanding becomes strong, you have to cut this, this and that's it, 4 * 5 = 20 From 20 we will make 444, so in this way you will do things, 440 will be subtracted from here, then directly l will come out equal to 240, you will do it like this so that your time is saved and you are able to understand things. Correct? Ok. see you next. Let's do the next question.
What's in the next question? Let's see a little bit. Let's read the question. The option is not visible. You have to find the answer.
A train moving at a speed of 60 km/hr, a signal, yes Babu, see what is a signal, you can write signal here, you can write a signal here, you can write the pillar or signal here, the signal is also small, the signal is also small, you will cross it with a prak, it is very small in comparison to the signal, you can write a signal also, see, even after seeing all these things, nothing happens, so it is coming here, a train moving at a speed of 60 km/hr crosses a signal and a platform in so many seconds, that is, the signal in 12 seconds and the platform in 27 seconds. Then what is the length of the train? So, what is the speed of the train, whether it crosses a pole, sorry, a signal or crosses a platform? There is only one. 60 kg per meter. Isn't it? That means the speed is constant. Yes, this is what is being seen. The speed is constant.
What is the speed sir? is constant. That means it is moving at a speed of 60 km/h.
So, you guys try this a little bit. Isn't it? After that see whether the answer is being given or not. In this the answer will be given in one go.
We will take this only. I will take this thing. We will not take this. If you take this alone, it will come out directly. Yes sir. This is how the previous one is made. Please take one along with you.
Yours will pass. Try whatever you can.
Do it a little bit. Let go. Please tell me the answer to this. You have to do the given one in the same to same pattern. Same to same pattern, no change.
See if we consider the signal then it crosses in 12 seconds. This, if we count the platform then this will become this.
So why would we conduct such a big session? We will take them one by one. So what is the length equal to? What is distance equal to? Speed * Time. Isn't it? What is distance equal to?
What is distance equal to? Speed * Time.
What is there in the distance, sir? In the distance space, we take the signal to be the length of the train l.
What will happen if we take the signal?
This is 60, right? In this we will do 5/18 because the option is visible in the meter. Correct? The option is visible in the meter. This is in seconds meters.
Ok? After that, we take 12 seconds here. It's done.
so much to do. l left. It went out like this.
You can also withdraw it by applying condition two.
How? What do you have to do if you carry the platform? You will have to do l + 250.
Then you will have to do 60.
This will have to be made 5/18 and here it will have to be made 27 seconds. So see, this doesn't look a little big. So we will work with the smaller one only.
Our answer will come in this. So why would you do that much? Do it sir.
Cut it and bring the answer slowly. This will be cut by six. This in two times. This will be cut by six. This 3 this is 20 isn't it, this is 40 4 * 5 = 20 4 * 5 = 20 it is becoming 200, see it is becoming 200, is n't it 200 meters, the length of the train, yes option number C option number C 200 meters are you guys doing it or not, are you guys understanding it or not brother, yes 200 meters, see, it will be made somewhere, this is a small concept, bigger concepts will come from this and we have read all the questions from the train, after this, in this one we will make almost a good number of questions because eight-nine questions have been asked from this chapter, eight-nine questions from this chapter, so we will first make approximately 80 questions in this chapter, we will practice 80-80 questions. We will practice 80 questions. Only then will our base become clear.
After that we will touch on PIQ.
Ok? After that, if we touch the PIQ, our PIQ will be created easily.
Ok?
Let's look at the next question. Make it. A train to a signal pole to a signal pole yes signal whatever is a signal pole.
Ok? A train crosses a signal pole in 11 seconds and is correct? Let's give you this. Make it and what is the length of the train which crosses the platform of so many meters in so many seconds? It will follow the same to same pattern.
We will take only one and take a shortcut. I will not write much now.
Let the length of the train be l. I have assumed. Correct? Now it has no speed.
What's in it? There is no speed. There is another problem in this. So what will you do if you don't have speed? There is no speed in it. So how will you remove it? Isn't it? So we will write two. If time is given then look at the speed, a train is crossing a signal in so many seconds and the platform in so many seconds.
Ok? No problem.
Look, I don't know the speed. We have not been asked to increase the speed. We have been asked to find the length of the train. So what will we do? Because the speed of this train is equal to the signal.
Just bring the question we made and you will get the answer. If you compare it with this, you will get the answer.
So it means that both of them have equal speed. Look at this 60, the speed here is also 60. There is 60 speed here also.
So, the speed of the train is equal to 60. It is 60. So what will happen in this? Suppose there are two cases.
What is the speed of the train? Is equal. We will equalize the speed.
So let's assume that you can make the speed equal.
So we can do this like this, if the speed bar s1 = s2 then it does not exist. The train is same at both places. Both have the same speed. So both will be the same. So what can we do? s1 s2 we write like this.
So in one case, we take the pole on one side and the platform on the other. So what can be done? What is distance divided by? There is time. This means that if we calculate distance/time, it becomes distance vs time.
What is distance? l is. and crossing the signal in 11 seconds. Similarly, what will happen here? will become l + 260. Yes.
And how much time is he crossing in seconds?
Crossing in 24 seconds. This is the game. By moving this here it will come out.
By cross sectioning you can easily find out what it is. Isn't it? It will come out, right? Look, you have to do some multiplication and division and some subtraction. Here, equate the LHS to the RHS. The option is given here.
See what the option is?
The option has been given by making it dangerous. See what is there, make an option. I will give it to you people. My work is almost over. You guys do it. You guys make it. Isn't it? You guys please tell me the answer to this.
Where to drop the signal? If there is a signal, we will take the length of the train only. Babu, if there is a signal. Look, if there is a signal then we will only take the length of the train.
If there is a signal, only the length of the train will be taken into account.
Ok? Remember, both these conditions are important. If there is a signal then we will take the length of the train only. If the platform is initially the pool will be a big thing then they will take it. Ok?
Just have to solve it. Solve it.
Can anyone tell me what is the signal signal paper for ANM and JNM, your name is Kalyani Yadav, it is different, ANM's paper is different and JNM's paper is different, I understand, ANM's paper is different and JNM's paper is different, meaning ANM has a separate paper.
This is the ANM paper.
Like the syllabus of ANM. Look, the ANM asks 100 questions. Correct? He asks 100 questions and the one from GNM asks 150 questions. Understood? And there are different papers. It happens in the morning.
This will happen in the evening.
Ok.
Let's make it. Sonali Ruksar Parveen Anjali Savita Mehta whatever we are saying is correct 220 is coming which means 220 is not an option in this. So what will be the answer to this? It will become D number. Everyone is saying that the length of the train will be 220.
This is your 220 meters which is not in the option. So this way option D can also be there.
Ok? Incomplete information Information incomplete. You can write here, is the information incomplete? Meaning that information is not available here. There is no information about 220.
Sorry for the spelling mistake.
I want to know that at the time of filing the form, both the forms have to be filled separately. Will take different money. The government will take different amounts of money from you. Ok?
Different forms have to be filled. Will take different money.
Ok. Okay, it's done.
Yes, absolutely correct answer. Let's make it further. I am going to ask you guys a question.
I am very impressed with you all because you got answers. A train in its own direction.
Now look at that direction a train in its own direction in the same direction. Is it okay Babu?
Look, the one from Disha has come. A train is going in its own direction at the speed of 2 km/hr and 4 km/hr respectively, then it crosses so many persons respectively, then the train crosses its own length. The height of the person will not be added.
Correct?
So it crosses in 9 seconds and 10 seconds.
So what is the length of this train? Ok?
Now look, I have given you speed. So you will not equalize the speed. Now a separate system will be created. Now we are trains going in the same direction.
Both are going in the same direction.
What he is saying is that a train is moving in its direction at a speed of so much due to the actions of the people. Now whose move is this? It is not about the train. This is the trick of individuals. It is the behavior of individuals. Understood? It is 2 and 4 km. Is. That's the move of Person One and Person Two. Understood?
This is the move of Person One and Person Two.
Ok? Will you be able to make this question?
See, if you can make it then you will be able to make it. So look, I will guide you a little.
Now in this case, the length of the train is becoming the same in both the cases. Now the speed does not have to be equalized, when will the length of both come in form? Hey brother, why are you asking the same question? I am saying it. It will be in the last of July. The exam will be held in August. They are saying that the form has not arrived yet. He will come last. Some people have not even appeared for their B.Ed exam yet.
Right now you guys will have to wait a little in this session. I feel so.
So look at the same train, what is it?
A man look at the direction there is a train. Let's say this is Man One.
What is? This is Man One. Understand that there is Man One.
What is its speed? It is 2 km/hour. There is another person. The other person is going this way. In the same to same direction.
This is Man Two. Man two is. Look at its speed, 4 km/hr is the speed of men.
So what is the speed of the train? So let's see the train here now. The train is also going this way. Suppose this is a train and what is the speed of the train? x km/hr. It is going like this. Everything is going in that direction.
Man Forest is also going there. The man is also going there and the train is also going here. Because he is saying that the train is moving in its own direction. 2 km in the direction in which the train is going.
4 km per hour Two people are walking at each speed. What is its timing? What is its timing? One is 9 seconds. 9 seconds and one is 10 seconds, this is 10 seconds, this is what it is saying, this is the data given by us, it is asking us to find the length of the train, so what will we do, in both the cases the train is crossing the person, now no one is crossing the platform, he is crossing the person only, so when the length of the train is crossed then the l of the train here will also be equal to l, you will say how did you do it, suppose whatever is happening in 9 seconds is also equal here and whatever is happening here is equal to here, so this is equal to the length and length equals distance and what is distance equal to? What is distance equal to? Speed * Time. So what will we do if we do speed * time? S1 * T1 will do the same thing no matter what. Isn't it? Here we make L1 L2 equal. Make the length equal. Whatever it is, both are equal to each other. S1 equals T1.
So S2 and T2 become equal.
Now they will say, Sir, what speed will you want? Look, suppose this is for person one, suppose this is for person one and this is the length for person two, okay, then see what is s1, what is the relative speed, when they go in the same direction, then what will be the speed of both of them, there will be subtraction because they are going in the same direction, so if it decreases then it will become x - 2, what is the time given, sir, time is given, it is 9 seconds, yes or no, 9 seconds are given, yes or no, see how this was done, see a little how this was done because see here it is in kilometers per hour and the answer is in meters.
See the option is in the meter. 45 meters, 50 meters and whatever it is is in meters. The option is in the meter.
So whatever it is, what will happen to you here? If you change this, how much will it cost? Will change in 5/18. Ok? One side is done. On the other side, we will take s2. What? We will take x - 4. We will take x - 4.
Ok? Will multiply. How much time is there? It's 10 seconds. It is 10 seconds and this is in km/ h, so we will convert it.
Kilometers/ta means 5 / 18 is there any problem? No. Just from here you will enter the value of x and since one side is the length, then your distance of one side here will be calculated. The length will come out or if you put it here then the length will come out. Wherever you put it from either side, the length will be found. So this was its solution that l1 = l2. This happens.
So later take out l1 or take out l2. Both are beans. From which you will be able to take it out later. You can take it out easily.
So first you look at what you have, what will you do? Let's take a step forward and do it. Ok?
Session it. So a little bit.
Because what is x? There is speed. We do n't have to increase the speed. What do we have to remove?
We have to find the length of the train. Meaning, first we take out the value of x, only then it will be equal, then this will cancel, this will be multiplied with it, so 9 x, this will become 18, this will become 10x and this will become 40, if we bring it here and take it here then it becomes 22, see, 22, okay, so x = 22, this is 22, 22 meters per second, this is the value of x, our speed has come out, this is okay, our speed has come out, now we will say sir that the length of the train has been mentioned, here the speed has not been mentioned, so the length of the train is equal to this, see, this is the length of the train, that is, you will have to put it completely, so put it, what will it become equal to, put it completely, what will this complete term become, see, if we put this in place of x, we will multiply 22 and 2, this 9 and this 5 / 18, this one-sided one will be put.
Look, the length of the train has been covered in two times. Correct? And it's turning 20.
20 this 10 this will become 10 and it will finally become 50. 50 meters, so this 50 meters will be our answer. Ok?
This 50 meters will be our answer.
Write all this down. I will upload the PDF.
Meaning whatever test you upload. Ok? So you guys can also try doing it at home.
Ok? There is some substance in the question. Now look, it is a train, so we said a little in the train, no sir, this is just starting. Every question will come from this also. Ok? Because a good number of questions have been asked from the train and for this I have taught you the entire base concept of speed train and distance, these things will be formed from the habit of that, did you understand any problem, are you taking notes? I did not understand the last step. Correct? You did n't understand this one, this one, right? Look, this x is gone. got it? x is gone. You must have understood. You must have understood what this x turned out to be.
x which turned out to be 22 meters per second.
What has been told to us about the length of this train? Tell me that. So the length of the vehicle was known from the speed. So we have to find the length of the vehicle.
So Babu, you have to find the length of the vehicle.
So you can calculate the length of the vehicle like this: what is l equal to?
l = s * t. Take s and t in, right? So look how much is s? Look, what is the length of l? How much did it cost? It turned out to be 20.
And how much time did it take? See how much s turned out? It turned out to be 22.
G22 came out. Look at this, the time came out to be 22, see l is equal to s * t, so this came out to be 22, so we put 22 and what will we put in place of t, tell me what will we put in place of t, put 9 seconds in place of t, right, put 9 seconds, so we will put 9 seconds, okay, we will put 9 seconds, wait, wait, speed is not that, speed is different, speed is not that, sir, what is speed, we have to find out the relative speed, speed is x - 2, so 22 has come out, this is the value of x, so the speed that will come out will be 20, so here we will write 20, two will be subtracted, we will get 20 and the 20 that is written here for two, so it was nine, so we will write nine and whatever is the speed in kilometers per hour, you will write it like this and you will multiply it by 5 / 18, see, 5 / 18 has come out in kilometers per hour, so that will have to be multiplied, this went in two times, hey brother, this went in 10 times When I went, this came out to be 50.
Look, this is the distance, right? This is our speed * time speed, which is x - 2. The speed that is found has to be taken as relative speed. Isn't it? The train is going, the person is coming.
So the relative speed of both has to be taken.
Understood? What is the name? Muskan Parveen is it a loss or a loss? Ruksar Parveen. My name is Ruksar. Ruksaar is reading the damage.
Come on, practice at home once or twice. There will be a question.
Make at least 10 questions about a train. Isn't it? If it's your first time, make it 10. After that we will upload the test in the app. Take the test and after taking the test, you should complete it completely. Only then will you understand.
After that, when you make the second video, you will understand it completely. Whatever happens the first time, a little bit happens, sir. A train travelling at a speed of 60 km/hr passes another train 170 metres long and travelling 80 km in the opposite direction. It is going on. If you had crossed this much in seconds then see the first train, it asks you questions like this. You see, he asks questions like this. Let me expand the question a little.
Now let's shoot in the options. He asks you questions like this. Isn't it? And you get scared. It doesn't happen but trying doesn't mean giving up.
This is a good question. There is a train running at 60 km/h and another train is 170 m away. There are two GO trains. There are two trains.
Ok? Suppose there is a train. I do n't know its length.
What is the length of the first train? Don't know. Let us assume it to be L. It is L. I don't know. Let the first train be A l. So a train travels 60 km. Is it okay to walk at the speed of? 60 km It is moving at an hourly speed. How much is it running?
It is running at a speed of 60 km/hour. He is saying another train which is another train. The vehicle is facing the opposite direction, which is considered good in the opposite direction.
Whose? He is coming forward. What is it, it is coming in the opposite direction. Meaning, there is a car which changes the colour of the car. There is a vehicle coming from here and its length is given as 170.
It is given in meters. See how much speed is given in meter to kilometer?
Coming in the opposite direction. Its given speed is 80 km/hr. He is saying this. Ok? Everything is going on. In how many seconds do they cross each other? So the time of intersection i.e. the time of meeting is 7.2 seconds.
Everything is in seconds. So brother, whatever speed it is, speed, speed, which speed?
What will be the relative speed? Yes, both will be added. There will be an addition, both of them will become 140.
What will happen? 140 But we do everything in meters per second because in kilometers no map is visible here in the option. Ok?
So what will you do? If this is multiplied by 5/18, it becomes its value in meters per second.
Both of them got together. 140 is gone. We will cut this much later. First the speed was this much.
The speed has gone up so much. And what is the distance? What will be the total distance, brother? What is the distance? There are two trains. Look Babu, whether he crosses the platform or crosses different trains. So its length is l and the second is the length of the train, so the distance between the two gets added. Whether it is a train or a platform, a swing or any other train on its own, it will still be added.
Keep this condition in mind also. If there is any other train, its length will also be added. So what will be the total length? l + 170 what? L + 100 70 ok? that'll be. And what is the time, sir? Time to meet? So see what time is it sir? It is not 1 but 7.2.
7.2 seconds. Now look, you have time, distance and speed. So what's up with you? The value of l will be returned. So, what happens, sir? What is the distance equal to?
You must know the distance is equal. Distance equals speed * time. So, it's all out there. So, what's the problem then? It will be made easily. Isn't it? Everything has already come out. Look, we took everything out easily. The question looks hard, but see how easy it is becoming, it will become. What now? What is Joe Distance? l + 170, okay?
What is the distance between here?
How much is the distance? Sorry, what is the speed? It's 140 * 5 / 18 right? If we multiply 7.2 by 7.2 like this, it will move down and become zero. If we subtract this point, it becomes zero.
Ok? Just cut it like this.
The answer has come. We will subtract 170 from that. Done.
What to do? 72 18 * 4 = 72 18 * 2 = 36 yes 18 * 4 = 72 ok? This 0, this 0 cancels 14 * 5 70 and 70 * 4 280 280 so what will be equal to this, this 280 and 170 will go there - 170 answer how much will be 110 so how much will be equal to 110 yes 110 meters is the length of the train, the length of the first train is 100 so many meters, see your option which is visible in A 110 yes see I have found it out, I have found it out while explaining, it means I have intelligence somewhere, it is a good thing, you are understanding things, if you are asked questions like this then you will have to make it, right? Yes, the question is easy, see the creator has made it, the creator has made it, Veena Kumari has made it, come see the next question, it will be in the same pattern. Right now we had thought of asking 20 questions. But whatever you guys have is fine. What time is it now? It's been 53 minutes. I had to explain a little here and there, that's why so much happened. It takes a little while to start. A train crosses two bridges of length 800 m and 400 m in 100 sec and 60 sec respectively.
What is the length of the train?
A train is 800 metres long and 400 metres long. There are two bridges.
This is the length of the bridge. Ok? Now the length of the train is not known. Will connect everyone.
See how to do it. The speed of the train will remain the same. Do it quickly brother. do it.
This question is also easy. It will be similar to what was made before. Let us assume that the speed of the train is because here let us assume that the speed of the train is equal. If you don't know then the value will be constant and equal. So what does speed equal, sir? Speed equals distance /time. So what is the distance? Let the length of the train be L. So L when crossing a bridge covering 800 metres takes 100 seconds.
Ok? And L plus when crossing 400 meter bridge takes 60 seconds. This is what the game is all about. The game is over. That's where L left off.
L then left. No problem. L left comfortably. Zero Zero cut. This is three times, it crosses five times, it will come here 3l, it will become 2400 3 * 9 = 2400, it will go there, l, ok, no, it will become 5l, do it, you guys also do it, 5l plus this 2000 4 * 5 = 2000, so this two goes here and this 400 goes here, so l is 2l equal to what will come out to be 400, like this it will go here, so this 400 will go here, so 2l, so l is equal to 200, 200 meters, okay, 200 meters is in the option, yes, option number C is the right answer, it is 200 meters, isn't it?
If a train running at a speed of 72 km/hr crosses a 260 meter long platform in 23 seconds, then what is the length of the train? I agree that the train is the same.
This is the same question as before. The question is the same as before. Nothing. What is the distance equal to? Length of the train. So what is distance equal to? Speed * Time. So what will you take in the distance?
What is the speed of the train when the length of the train is 207 times the length of the platform? Is the answer given in 72 km/h meter?
Yes, everything is given in meter. So we will multiply it by 5/18.
What is the time, sir? 23 seconds it's 18 4. Correct? Let's do this, now it has become 260. It will pass easily.
4 * 5 = 20 Multiplying 20 gives 460. Ok? If it goes here then it will be 200, so if it goes here also then how much will it be? It will become 200. It will decrease in both, it is visible that 260 will decrease, this will give 200 meters, it will be done on its own, a little basic, you will not start subtracting like children, you should have some common sense on your own, okay, you have to work by applying some common sense on your own, yes, you have to work by using your brain, if caution is lost, accidents happen, that is why you have to be careful and avoid accidents as well, so you will have to prepare everything, if you are late, no problem, the video will be there in the app, you can watch it comfortably anytime, okay, you can watch it anytime, okay, not many people come live on YouTube, that is why it is not live, it is a recorded video, okay, watch it recorded on YouTube, whoever has time, they will watch it after crossing it because many people do not like to give time, not many people do give time, their time is very valuable brother, not in studies, now they will give hours and hours of time in reels, everyone is listening to Mamta Didi's story. It's done.
Let's look at the next one. Make the number eight.
A train which is 300 km. It is easy to take a train from one pole to the other at a speed of. There is a pillar. Pillar pillar pillar pillar pillar. Ok?
So if there is a pillar then there is no problem. If d = s * t is the pole then the empty will be l. The length of the pillar does not add up. Correct? It is 360.
How much will you multiply this? Yes. It is in meters, right? That's what has to be seen. This is in meters. Ok? The option is in the meter. So we will multiply it by 5/18 because it has to be changed. After this, when we multiply it by 3.7, one zero will be removed and 10 will be deducted from it. It will be cut. This zero, this zero is cut.
This 18 divided into 2 ni this 10 360 370 this 10 and this 37 310 this will become.
This will be done in meters. Isn't it?
Correct. Best time to teach sir.
Look, you guys work in the morning. It's a boy. Boys sleep in the morning. Isn't it? It is best in the morning. You wake up at 3:00 in the morning.
Ok? And read it comfortably. It is the best.
I study at night. I study at night. I need silence at night and enjoy reading. Ok? The night is fine. It feels good only at night. Now I have heard that some people get up at 3:00 and study, so whatever is there in it is good. You will have to make a daily routine. Only then will the work be done.
But you understand the morning routine, right?
Sometimes it becomes difficult to wake up from sleep.
So they are made only during the day.
Work when you feel sleepy. Or there is a time when no one cares about you. Isn't it? After you have your lunch at 2:00 pm, this is from 2:00 to 5:00 pm. Isn't it? to 2:00 which is 5:00 p.m.
You read this in the gap. Because this is a rubbish time, especially in the summer days, in the summer, this is a rubbish time but for them, because for the students, this time is right, it is good for studying and for those who work, so a little bit Sir, when will the form for B.Sc Nursing be filled, look at B.Sc Nursing, the candidates of B.Sc Nursing, the form is going to come in the last of July, which means the exam will be in August, now I feel that the exam will be in August.
Ok? The exam will be held in August. Ok? It will go in August. So you guys wait now. I will let you know when it comes. Why don't you guys join our Telegram channel? They keep asking this question again and again that when will sir come? When? We have approximately 4000 candidates on our Telegram. Please make this question. Isn't it? Make. Make. There are 4000 candidates in Telegram. 4000 is something. So much information is available from there only.

Look what is happening, I don't understand it. It keeps moving, why is it like a reel, yes, see, you go here, you go to the website, you will see it in TM exam, understand, you can see here, we have a Telegram group, you can see the Telegram group here, we will show it to you, see, there is a Telegram group here, you guys stay connected here, see, it is there, see, it is visible here, you can join us on Telegram, here you can easily join on Telegram and you can also study B.Sc Nursing by coming to our website.
Whenever the form comes, we will update it here. So everything is mentioned here.
Come to the website and keep watching. You will get the form whenever it is available.
Ok? Let's make this question. There is a 150 meter long train running at a speed of 60 km per hour.
90 km in the same direction. A train travelling at a speed of crosses it in so many seconds. There are two trains.
What is the length of the second train?
So the first train is given. Now see where this is going? Let's read it in English.
A 150 meter long train is travelling at a speed of so much. Ok? A train travelling in the same direction. Now look, a train is going in the same direction.
Another train is going this way.
So the length of a train is 150 metres. It is in 150 meters. What is the speed sir? The speed is 60 km/h.
90 km in the same direction. Is going to.
Its length is not known. She is asking the other one to find the length. This is the second one.
Its speed is 90 km/h.
What is the meeting time? The time is crossed in 54 seconds. The second one is the same. Isn't it? Distance equals speed * time. Ok sir. What is the distance? One is 150 and the other is l, both will exceed. So what will happen to both? The length will be added. Isn't it?
What is speed? Relative speed. We will find the relative speed of both. How much will it be?
Both are going in the same direction. So it will decrease to 30. It will be 30. Both will decrease, right? 30 meters = 30 km/s second, so we will write 30 because the answer is in meters.
Look, what will happen if the meter is telling the answer? This 5 / 18 can we do it yes or no? And what is the meeting time? This is 54 seconds. Multiply 18 * 3 = 54. 3 * 5 = 15 and 15 * 3 = 45 means 150 = sorry not 150, if we write l then what will be the value of l? This l will become equal, this 450 - this 150 is becoming 300, 300 meter long train is becoming 300, see just calculate the number, yes number nine sir, please reply sir, NI approval will be given, IMC approval will be given, sir, it is not going to happen on 28th June, who said on 28th June, where are you talking about, you are talking about Bihar, Riddhi Kumari, you are talking about Bihar, you are talking about Bihar, maybe you are talking about Jharkhand, okay, 300 meter art number 10, make the question, now take the remaining test, after making these questions, the remaining test will be uploaded. Isn't it?
Rest of you guys please upload the test. You people have gained a lot of knowledge. Same to same type and 10 go. After that a little hard, then moderate, then moderate hard, we will continue like this, right?
Ok?
Two trains have the same length.
Two trains of equal length. Ok? It is the same. Ok? It is moving in the same direction with the speed of so much and so much respectively. Come on brother, he is going here.
Its length is l. He is going here. Its length is also l. Both are of same length one is going at 44 km/hr and one is going at 38 km/hr. If we calculate the relative velocity of both, what will it be, sir? If we calculate the relative velocity, what will it be? Both will decrease in the same direction. 6 km It is happening. It is becoming 6 kilometers per hour. Yes or No 6 is happening. 2 will become 6. Ok.
What is the meeting time? It's 48 seconds. There is no problem sir. d = speed * time distance will be the length of both l + l added together. The length of the first train and the second train will be added. In terms of speed, we will take six. But here we will multiply by 5/8 because the answer is given in meters.
What is the time, sir? 48 seconds. Isn't it? Is it being cut? It's going away. This in three times.
It's going away. How much per bar?
In one go. So 16 * 5 = 80 right? 80 so this l and here it is happening 80 this will be cut. So this 40 will be l which will become 40 meters. So both the trains are of 40-40 meters.
What is the same number? So what is the length of this train? So this is also 40 for both the trains.
Length and its also 40. This is the answer. Correct? Done. It's Rias. Only these word problems come in the math syllabus.
What words?
Jharkhand exam will be held in August. Now the form will come in the last week of July. Ok? There are no guarantees in June.
Polytechnic exam has not yet been conducted in June. If the B.Ed exam has not been conducted then he will give it for you people first. It is impossible. INC is a college in Rupi, brother. Rupesh is from the same college.
Borim Sir, look there are more questions but all these questions will be given in the form of a test.
You guys go to TM Exam App. There is TM Exam App in Ojhar Exam App, you can take the test there. Ok?
Now let us test all the remaining questions.
Not just today, let me give you a little gap today. You understand it's a little bit, right? Understand what you are, understand things a little. Ok? If you understand, things will be better for you. It will be easier for you to do things as you are. Ok? Let us go.
Goodbye
