1)

x% more than y = 69

y+ xy/100
insufficient to find xy/100

2) x% less than y = 51

y - xy/100

on combining we can find

xy/100

x/100 x y ~ x% of y

(C) imo

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
