IS \(x - x^2 > y -y^2\)

or, \(x-y>x^2-y^2\)

or, \((x-y)>(x-y)(x+y)\)

Statement 1:

x>y or (x-y)>0

hence question reduces to is 1>(x+y). No other info

insufficient.

Statement 2:

\(x^2>y^2\)

\(x^2-y^2>0\)

(x-y)(x+y)>0. No other info.

Insufficient.

Combining 1 & 2 we get, (x-y)>0 and \((x^2-y^2)>0\)

but still we cant find the relative relation between the two

Hence it is insufficient..

Answer E.
