Yes. Yes.
That's why everything is fine now. It will work.
Andrew or today's session again what amount is 10% more than 90. So and just after this question just before sleeping means just practice 30 seconds and after that.
So here is the first question 10% more than 90. So 90% 100 divided by 100. So cancel 99 and these questions.
Okay. In your examinations all these questions are very important.
So 30 seconds 20% less than how much% is salary more than means or morning that's Okay.
25 answer 25%.
So let's check whether Rick's answer is correct or not.
20% less than so 20% less.
Now how much percent is more than so this type of question I salary that's why 80 into 100 person and 20 good Sir formula question number 53 and solve because many times YouTube videos 225 solver into 11 is equal to 136. Six again MCS at that time 200 300 400 but no problem but still we will solve reasoning questions 11 first of all division First of all, division 225 15 plus x into 11 11 x 136.
Now 11 x 15 right hand side 121.
And if 11 x is 121, x will become 121 by 11. 11.
No, 11 is correct answer.
Next.
Uh, question number 54. Yes, 54.
In an examination, X scored 10% more marks than Y and Y scored 5% more marks.
So, X marks question Z score out of 400. So 75% score Y in 5% score.
So 80% score X in 10% more than Y in five only out of 400.
So out of 400 score percent so 100 300 by4 is 75% a score z in now y scored 5% that's why panga can increase 5% more than zanya so 75 + 5 80% a score X scored 10% more than Y. So X in 10% Y 90% score X mark so X 90% of so option C 400 300 out of 400.
down means 300 marks out of 400 in which first Zang 2005 in add value.
Now this one if the price of tea is increased by 50%.
By what percent a housewife reduce consumption? so as not to increase the expenditure of the family on tea. Second 30 seconds I think 30 seconds more than enough.
No problem.
over t is increase by 50 and 50% increase. Okay. uh so as not to increase the expenditure of family on t okay okay okay.3 a by 100 minus a into 100% direct increase increase a by 100 + a into 100% so a50 50 into 100. So 50 in 153 time tree one by three person. Option A 54.
Total percent 300 by 400 percentip cancel or 300 for divide to 75% score z score 75 question Y scored five marks more than zed Y% score 80% score X score 10% mark score Y say Y X 80 + 10 90% score total mark 400 or 90% score to 4 into 90 360 marks.
Hope you got the point.
Borrowed a certain sum of money.
No problem.
Oh 12% peranom interest rate in he paid or compounded annually he paid back in two equal annual installment of rupees 784 each what sum did he borrow installment But two equal annual installment of 784 each.
That's why ratio method sum. So 12% foreign divide 3 by 25 25 month but two equal in two equal annual installment square A square 784 equal installment in each one.
That's why 1325 since two equal annual installment installment 2018 multiply multip 784 and 25 28 7 Zari zasari anidon add add this will be 8615 this will be 5213 okay now installment of 784 ea and installment value is 784 it means 78 84 unit is 784. So one unit value will be one anidon. And question what sum did he borrow?
So one unit value is 1325. So 1325 unit value will be 1325. Option B is correct answer.
And 57 here. 57 in triang.
Oh, so sorry. So sorry. So sorry.
Oh, sorry.
400. This is the principal. Okay. And 5% peranom. This is the rate of interest.
5%. Now P RT by 100 same rate of interest CI so CI formula P 1 + R by 100 ^ N -1 okay and uh what does he gain at the end of two years now gain gain obviously SI so CI minus SI value Y - X value two years. First case SI. Second case CI.
100 raised to the power 2. Now 400 5 square is 25 and uh z square is see 25 in 100 minor mistake.
Next, I'll give you 30 to 40 seconds.
Let's all sushila chhatri sushila And very more 58 again.
Simple interest find out. Simple interest formula is P R T by 100. Now principle on a sum of rupees XA rate is 16 time 1 year. Oh B more okay take Bang 56 ratio. Yes.
Formula formula is px 1 + r by 100 in 1 + rx by 100² for okay principle the sum. Okay.
Continue. B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B X by 5 time 1 year 1 year 3 months 1 year 3 month 1 by 4. Okay. 4 into 1 + 1 5 by 4 and 100 like this.
Now uh caution again four and five in 25.
So x by 5 is correct answer of this question.
It will be very good for you also. 59 here. A 5 m 50 cm high boring reasoning.
Atom is related to molecule.
Cell is related to what?
Cell is related to matter.
Nucleus battery nucleus nucleus.
So organ is made up of what? Basic building blocks. cell that's why organism is correct answer organism.
Now question number 77 here answer.

Next What type of question? Gate question.
Gate question 2018 or 2019 gate question and uh but because technical education 20 but favorite IC engine A concept.
It will look like this.
And this is the odd one. A next in a class of 4 to3 students a boy is ranked 19th when two boys joined his rank 77 in a class of it means at least six hours.
At least 8 hours.
Boring everything type of comfort. Now question number 89.
Fourth tree. Fourth tree.
Now a boy is ranked 19th.
Okay. Okay.
and 43 minus 18 means five and 26.
Okay.
20 five. Now when two boys joined his rank was dropped by one.
So 26. Correct answer.
So, so okay.
There are five students.
A boy is ranked three or two.
When two boys joined, his rank was dropped by one.
number one.
Now two boys joined his rank was dropped by.

Okay.
5 m 60 cm high vertical pole. 5 m 60 cm 560 cm and it casts a shadow of 3 mm cm.
Find the length of shadow cast by another pole of 10 m 10 m 50 cm.
So always and it is same. Okay.
And negligible very very very minute. So perpendicular by base equal to perpendicular by base. So see 560 by 320 1050 by X.
So this is the method.
Okay.
Yes. You reminds me to shak.
So zero 7 time 18 four time 7 in 150 time 4 in multiply 150 into 4 and means 6 m. Next question. A B A B C given A B C final A into 4 2 into 4 2 into 5. So 2 a.m. 2 4 5 option ma'am option C next sa is divided among A and C such that share of B is share of B is 2x five of combination of A C and question I given A plus B plus C aine now question B value so B value A mommy no a that's why cross multiply 5x 2 b so a c i in 5x 2 b so 5x 2 p plus equal to 1050 now cross multiply 5 + 10 15 b by 2 is equal to 1050 okay now seventh time and B is aa 2x 5 by 2. Yes, a correct no.
A B C. Yes, this is also correct.
5 by 2 a 5 by 2 7.
Yes. Yes. Yes. Yes. Yes.
5 B + 10 11 2 into B 2 B + 5 B 7 B to com 5050 and 300 is correct answer 300 question sir SP Question.
Last answer.
When will you give the exam?
Now this question A and B enter into partnership in A invest. So in each 24 and see like this tree time three Time 18 2 time 2 3 2 So 3 is to 9 is to five ratio into total amount 4,000 500 4500 is correct. 4500 course memes.
Okay. Eligibility educational qualification.
MES 60 welcome department.
Now this one next month and after that questioning G average of three number is uh 35 first number second number third number third number second number is twice the third first number is twice the second one and first and 35 one unit value will be and concl Question difference between largest and smallest.
This this is correct answer. Next 64. Average weight of eight person is increased by increased by type.
Okay.
Xuma 8x joani oh Lutheran a replace man whose weight is 60 kg is replaced by a new man so that's why total person but average is increased by 2.5 that's why like this now solve 8x - 60 + y is equal to 8 x + decimal 10 54 54 20 8 x 8 8 x 8 x cancel - 60 right hand side so y = 80 so 80 80 sorry 80 plus replaced by a new man okay increased Adik and uh H 80. Yes. Yes. Yes. 80.
20 + 60 is 80.
Everything is correct. 8%. Oh, everything is correct.
Every steps are correct. 8x and 2.5 into 8.
Oh, this is Bonus. Okay, this is bonus mark option answer compensate everything is correct and yes 8 and x 2.5 yes everything is correct a book is priced at zasuma Uh one paper two paper one ide 65 price is 150 and allowed a discount of 8%. Yeah. So 8% discount 92% 15 15 2 in 46 46 into 3 8 12 13 So 138.
Next this one. A dishonest a dishonest shop. A dishonest dealer professes to sell his good at cost price. Cost price.
900 lie in 1 kg. Yes. Yes. Yes.
person formula error by total weight minus error into 100%.
Total gain percentage. So error.
So this error 100% so 100 by 9% and 9 11 99 option Bik Okay.
So that's why okay means A exat customer Aexat this one if X% of A is equal to Y% of B a A Z% of A is equal to what% of Bh very LDC type X% of A is equal to Y% of B 100 cancel.
So 100 cancel and X Y.
So this mean then Z percent of multiply A. So z% of a means a y is equal to what percent of b?
So what a% of B now X okay like this now 100 and so sorry so XY Z Y by X ma'am option Candom because aspirants means percentage and decimal 68 concept 20% less than salary more than same to a by 100 minus a into percent. So a 20 and 120 somria into 100. Okay. Now 20 80 answer like this. Next total cost of 12 p and five pencil is 12 pen x assume pencil y can assume cost of one pencil is five less than cost of one pen also cost of one pencil.
Oh, is five less than cost of one pen?
X five less than cost of pen.
Pen minus pencil equal to 5.
Then only equation continue in form of x y - 5 = x like this.
Oh pen find out pen x and pencil y. So 12x + 5 and y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y = 5 + x 5 + x = 11 1. So 12 x + 25 + 5x = 5x 12 x 17 x 4 8 17 12 x 5 y.
Now cost of oh cost of one pencil. Oh cost of one pencil y is less than the cost of one pen.
Oh yes yes yes.
So 12 x + 5 y in x - 5 11 1.
So 12x + 5x - 25 = 11 1. So 17x = 136.
Oh 17.
Okay.
Option 5 pen. So 8 into 5 40 11 25 add. Okay.
A fruit seller bought a basket of 200 oranges. Profit and loss. 200 orange and one rupee in orange pane and a vine orange.
So orange cost price of 200 200 orange on opening the box he found that 10% of oranges were bad.
So 210%.
So 20 and now A T one orange three orange one orange 2x3 and orange 2x3 into 60.
So what will be the percent?
So gap is 20 by cost price is 100 in 200 can say 20% again is H1 20% in ABC earn together and A in LC 94 and AA BC 76 daily earning of C.
A plus B + C, A Cali and B L C 76.
C value find out and C value find out.
C value in the form of C A 94 minus C. So A 94US C B 76 - C B I 76 - A 94 - C plus B I 76 - C + C top 150 so minus C plus C and uh 94 76 minus C equal to 150 C inus 15 in.
Now this one 12 men or 18 women can reap a field in 14 days.
means number of days that eight men and 16 women women will take to repeat.
Because many times because 12 men can reap in 14 days.
One man in 1 by 12 into 14 women 1x 14 but one woman by 18 into 14 men 16 women. So one man value in each one 8 men will be 8 by 12 into 14 plus 16 women 18 into 14 12don like this and 8.
LCM is 36 3 time and 2 into 2 4 8 by 14 3 + 4 7 7 7 in 14 two time 2 in 8 four time 4 in 36 n if they work together one by pardon and flip and total days 9 days overall work confine One day assistant is normally filled with filled in 8 hours but takes 2 hour longer to fill.
Andrew assistant is normally filled in 8 hours but takes 2 hours longer to fill because of a leak.
hours by.
So 8 into 10 4 into 10 40 hours.
Next, an invoice of 2000.
An invoice of 2500 has the following terms.
And first condition instantly directly% within 10 rate of discount.
So within 10 days 2% discount within 20 days 1% discount and 30 days like that discount fully.
Now find the discount if the payment is made on the fourth day. Now fourth day will lie in first day within 10 days 2% discount.
So 2% of hemi 2500 25 into 2. So 50 rupees is definitely correct answer of this question. Okay.
Now question last question 75. A dealer marks his good goods 20% above the cost price. So cost price 20% increase.
He then allows some discount. Okay. some discount on it and marks a profit and makes a pro M A R K E S makes and makes a profit of 8% profit and 8% profit. So 8% profit selling price will be okay.
He then allows some discount on itount and makes a profit of 8% only price.
Okay. So discount now price 12 rupees rate of discount.
So rate of discount discount percent is always given as discount by mark price into 100. So discount is 12 mark price is into 100 12 in 10 time and please subscribe and notification bellwise notification.
John Chana.
Uh oh.
Exact language. Exact sentence.
Like that.
And good night to all of you. And please take care. Keep preparing, keep practicing questions. Not only maths and reasoning topic, chapter uh subject physics, chemistry, biology, static, GK, dynamic, GK, current affair, computer, English, economics, physics, chemistry, geography, history, thuk. That's why all the subjects consistent because consistency remaining flow break next week.
Okay.
Like that.
Yes. See you soon. Oh yes. But no problem.
Haters.
Haters.
And Hello for hook up the fresh one. I guess I'm just never like a one cups animal husbandry and vet vi department ldc exam arithmetic oh simple and yeah a h and oh I think thank you sir yes Most welcome.
Thank you.
