Last question can be done by another method. Let suppose, marks of each student is 85. Now as a removal of 2 students now avg marks of 38 students decreased by 1. So total marks of those 2 students will be= (2*85) + (38*1) = 208 And difference is 108. Now solve these 2 equations and you will get your answers. Benefit of this process is, you dont need to do big multiplications.

[@BoT-gb7qg]

bro can you explain why 85 is multiplied by 2 even there 2 students excluded

[@maaryah4331]

@@BoT-gb7qg because each individua; student gets 85 marks, so when those 2 students will be removed they'll carry 85*2 marks with them along with the extra marks due to which average is degraded and the degraded marks are 38*1, so combining it, the total marks of those students would be= 85*2+38*1

The hotel question can be done similarly too - The new average of all 16 men becomes x and to make it easy assume everyone pays x amount, But the actual amount 16th man pays is = x +75 This extra 75 was distributed over the rest of the 15 men, increasing their amount spent by 5 (75/15) to reach x. So, x = 80 + 5 = 85 Total bill = 85 x 16 = 1360

[@ryzen7-wp7gs]

​​@@chintuharyanvi4249 16 men are paying their bill so avg = x ( suppose ) 15 men pay 80 rs each so avg should be 80 right ? but 16th guys pays some amount which isn't 80 . ( Only 15 men pays rs 80 ) Which results in a new average = x X is the new average which is larger than 80 Now if hes paying 75 more than " x " that means he pays x + 75 So remaining 75 will equally affect average of 15 contributions . +5 for each contri making the new average for 15 men 85 Now ( 85(15)+x ) /16 = new avg ie x So x must be 85 itself

In the second last qs. I was not able to clearly understand the explanation of 48-25 to get 23 years as the answer. So I just assumed total age of members to be 500 before and after 5 years 525. By this way it was easier to understand how 23 is the answer.

[@whobhamx]

I had the same doubt but i think that the replacement of elder daughter is after 5 years so the -5 years is included and if this case is not considered and if you assume that daughter in law is replaced at the beginning then the -5 years will be taken from her age i.e 28 so basically 28-5= 23.

[@shrutirp4084]

The average weight of 40 students is 45kg. If teacher is included and one student is excluded, the average weight increases by 1kg .If the weight if excluded student is 40kg. the weight of teacher is ? Please answer using method taught by sir. As im getting answer as 85Kg and right answer is 80Kg. ?

[@PrinceThakur-in9zl]

p1 p2 p3...........p39 p40 p41(teacher includes) Eliminate p40 (student exclude) p1 to p41 =40 persons(we eliminate p40) Avg weight increases by one of all 40 persons, so, 40 *1=40 Student excluded's weight =40 So Teacher 's weight will be more than 40 40 +40 (40*1) 40+40=80kg

[@sankettari8891]

In hotel question its written they have paid 80 each of 15 member so the avg is 80 and 16 person paid 75 more than avg so He paid 80 + 75 THE ANS SHOULD BE 1355 HOW CAN IT BE 1360 I M NT GETING IT!!

[@snehatsamuel30]

the 16th man paid rs 75 more than the average of the 16 men...not average of 15 men .. therefore you have to find the average of alll 16 men and then add 75 to the average bill of 16 men ..which will give you 16* average bill + 75

[@ruthwikrao9603]

lol, even i did the same thing, logic is wrong

[@36_parthshrimali84]

So just in short way, i wanna give answer that , first you said that average bill his 80 , okay? And in the last you said total bill is 1355, so the average bill is (1355/16).. Both average is Different... I hope you'll try to get it..

[@sharonraj6942]

@@36_parthshrimali84 the answer is 1355,total=80×15=1200, 80+75=155, add 1200+155=1355
