If x and y are nonzero integers, is \(\frac{x}{y}\) an integer?

(1) x is the product of 2 and some other integer.

(2) There is only one pair of positive integers whose product equals y.

The questions is asking whether X is divisible by y or x is a multiple of y.

Statement 1: x = 2 * q . here q can be any integer other than 0. therefore not sufficient

statement 2: Only a prime number is a product of two positive integers. therefore y could be any prime number. Not sufficient

combined: no link between q and y, therefore not sufficient.
