\(X\) , \(Y\) , and \(Z\) are positive integers. Is \(X%\) of \(Y\) bigger than \(Y%\) of \(Z\) ?

1. \(X = Z\)
2. \(Z - Y = Y - X\)

Question asks,

is (x*y)/100 > (y*z)/100 i.e is x>z

1) gives us the answer NO, thus sufficient

2) X = 2*Y - Z

Considering x,y,z are +ve numbers, X can be greater than Z or less than z

Thus not suff.

A for me
