If x and y are positive integers, is x^16 -y^8 +345(y^2) divisible by 15?
1. x is a multiple of 25, and y is a multiple of 20
2. y = x^2


It is obvious that statement 2 is sufficient.
From Statement 1 , we can also conclude that it is not divisable by 3 and therefore not divisible by 15 .
Therefore answer should be D.
