I think the answer is E.

Statement 1: N^2=N. N can be either 0 (even) or 1 (odd)...not sufficient.
Statement2: N^3=N N can be either 0 (even) or 1 or -1 (odd)...not sufficent
Combined, N can be either 0 or 1...not sufficient.

Is that correct?

That's not correct. 0 is an even number.
So, n can be even or odd => not sufficient to determine if n is even

[quote="Jivana"]Is integer $$N$$ even?

1. $$N^2 = N$$
2. $$N = N^3$$

FROM 1

N= 0 OR 1 OR -1....EVEN OR ODD...INSUFF

FROM 2

N = 0 OR 1 OR -1...INSUFF

BOTH
N^2 = N^3 , -1 IS RULED OUT HOWEVER N CAN = 0 ( EVEN) OR 1 (ODD)
