What is x% of y?

(1) x% more than y is 69

(2) x% less than y is 51

We will have two equations from the two statements.

Statement 1 gives y + xy/100 = 69

Statement 2 gives y - xy/100 = 51

Substituting xy/100 = 69 - y in the second equation,

we can find a unique value of y and lead to finding the value of x

Therefore, Option C is the answer as both statements are needed to solve this question!

P.S We always need two statements to solve for a unique solution, when we have 2 variables
