If x and y are integer, which of the following must also be an integer?
I. xy
II. y
III. y/x Choose the correct choice from the following options:
A) I alone	B) II alone	C) III alone	D) I and III	E) None of the above
Let's take X = 4and Y = 3   Then X/Y = 4/3 Not an integer.   Y/X = 3/4 Not an integer.   Y alone is 3 which is an integer.   Hence II alone.
