How many pairs of natural numbers satisfy the condition that the sum of their reciprocal is 1/12?
Q2...method plzzz
A overtakes B in 1/5th of the 10th round. Whats is the ratio of speeds of A and B? I think it should be, A/B = (9+1/5)/(8+1/5) But in IMS booklet I found it given as, A/B = (10-1/5)/(9-1/5) Where am I going wrong?

You have a bundle of 500 coupons which are somehow attached to each other. You have to pay a coupon to the mess each day for 500 days. You will get back change if you pay more (e.g. if on a particular day you pay using a piece of 5 coupons, you can get back 4 coupons). However you are the only person who use coupons to pay and hence you can get back change only if the mess worker has sufficient change with him (which is only possible if coupons were paid by you earlier). There can be no arrears/advance payments. You have to break the set of 500 coupons into pieces. What is the minimum number of pieces with which you can successfully make all 500 payments?
One fine morning, while leaving for work, Mr. Bean looks at the analog clock hanging in his apartment, through a mirror. As it is Mr. Bean’s clock, there are no digits on the clock, so by mistake he takes the mirror image as the actual time. He rides his car to work, which takes 40 minutes. On arrival, he checks the time in his office clock. He is shocked to see that it took him 3 hours and 30 minutes to reach office. When did Mr. Bean start from his home?
Three friends are arguing on the number of people that might be standing at the queue of a famous tourist spot that they were going to visit the next day. They make the following statements. Friend 1: There will be at least 10 people standing in the queue. Friend 2: There will be less than 10 people standing in the queue. Friend 3: There will be at least 1 person standing in the queue. The next day, it turned out that only 1 of the three friends was correct. How many people were standing in the queue?
Why in Explantion value of atleast one and atleat two is taken 100% and 90% and min of atleast 3 as 80%
Q: A survey was conducted and the details of CAs in the industry were
collected :
Total: 2600.
Percentage wise distribution of different Queries are:
Name Age Address Experience Phone Email
100% 80% 50% 40% 50% 90%
For example, of the total number of CAs of only 50% viz, 1300 people
gave their experiences.
1: For at most how many CAs exactly five of six features are available:
(1)1300
(2)1950
(3)2000
(4)1820
(5)None of the above.
Explanation given is --->
I said If we want to maximise exactly five then atleast six will be minimum(zero if possible) and atleast one, two, three and four equal to or almost equal to atleast five as these values can't go lower than atleast five.
Now in this case: If I am making exactly six to be zero then I need to divide 41% in five categories and for maximum value of exactly five I will distribute 410 equally i.e. 410/5 = 82% each.But least value for 'atleast one' is 100%.
So removing that one figure, using same logic as earlier, I will divide remaining 310% (410% - 100%) equally in four categories i.e. 310/4 = 77.5% each.
But again least value for 'atleast two' is 90%. So going by same reasoning, remaining 220% (410% - 100% - 90%) should be divided equally in remaing three categories i.e. 220/3 = 73.3% each.
Oh No! Once more the least value for 'atleast three' is 80%. Now removing this one, I need to divide the remaining 140% (410% - 100% - 90% - 80%) equally in remaining two categories i.e. 140/2 = 70% each.Now That is OK. Atlast! Here I get my answer, the maximum number for exactly 5 as 70% of 2600 i.e. 1820
At what time in the clock does its mirror image differ by 2 hours 50 minutes ?

How many natural numbers divide exactly two among 84,120 and 210?
Approach?
There are two distinct natural numbers. Each is first increased by 10 then by same percentage as each was increased for the first time. Each number finally results in 72 Find the difference between the numbers.
There is an escalator and 2 persons are climbing down on it. A climbs down 50 steps and B climbs down 75 steps while the escalator is moving down. Given that the time taken by A to take 1 step is equal to the time taken by B to take 3 steps, find the total number of steps in the escalator while it is stationary.
A)100
B) 90
C) 80
D) 85
