Statement 1 - N = x/16
X is even. As there is no multiple of 16 that is odd.
PS: N is an integer
Statement 2 - N = Y/32
Y is even. As there is no multiple of 32 that is odd.
PS: N is an integer
Hence, the answer is D.
X is even. As there is no multiple of 16 that is odd.
PS: N is an integer
Statement 2 - N = Y/32
Y is even. As there is no multiple of 32 that is odd.
PS: N is an integer
Hence, the answer is D.

If N is a positive integer, is X*Y an even integer?
(1) N = X/16.
Since N is an integer, it means X is even integer, because only Even/Even gives an integer
But Y can be integer or Non integer . Hence X*Y can be Even integer or a non integer.
It is insufficient.
(2) N = Y/32.
Since N is an integer, it means Y is even integer, because only Even/Even gives an integer
But X can be integer or Non integer . Hence X*Y can be Even integer or a non integer.
It is insufficient.
Combining Both Statements 1 & 2, we get
X and Y are even integers, hence X*Y is even integers.
