Given less than 100 people were surveyed

St 1. X = less than 65 Does not tell anything about Y Not-Suff

Ans : E

Another way to look at this question . Total given is a range.Total can be any number from 1 to 99 ( total <100).

(1) X is 65% of Total => X can have multiple values as total is not fixed => Not Sufficient .Unable to get a single value for Y

(2)Both X & Y = 10% of Total => multiple values => Not Sufficient .Unable to get a single value for Y

(1) & (2) together also does not help to get a single value for Y.Hence answer is E

it's a one line solution problem.

we know just one thing and it's less than 100 people, 1 to 99 anything . 99cases not only double cases..

so its not possible to evaluate how many people used Y or X or anything else, just by using % .

so (E)
