OPTIONS:

Read Solution (Total 2)

IF we assume quotient to be same in first two equations by given data, then we get remainder as 22.5
but if we dont assume then, we dont know quotient so data insuffiecient
so i think here data is insuffiecient according to options..

TCS Other Question

Guys I had my apti today. There were some 3-4 different sets with similar questions but varying data. Most questions(round about 20 out of 30) in my set were from m4maths & techcse. Practice well & keep track of your time.
Our apti result will be declared tomorrow. Lets hope for the best! Good luck to you all. A committee of 6 is chosen from 8 men and 5 women so as to contain at least 2 men and 3 women. How many different committees could be formed if two of the men refuse to serve together?
