GMAT Data Sufficiency (DS) | Re: If x, y ≠ 0, is x/y an integer?

If x, y ≠ 0, is x/y an integer?

(1) x is prime.

Let's say x is 3 and y is 1, then x/y = 3, which is an integer
But if x is 3 and y is 2, then x/y = 3/2, which is not an integer.

This statement is not sufficient.

(2) y is even.

Let's say x is 4 and y is 2, then x/y = 2, which is an integer
But if x is 3 and y is 2, then x/y = 3/2, which is not an integer.
This statement is not sufficient.

Combining both statements - X is prime and y is even

Let's say x is 2 and y is 2, then x/y = 1, which
