If x and y are integers and x divided by y is 15.15, then which of the following integers is a possible value for the remainder when x is divided by y? I. 15 II. 5 III. 3
Choices:
A) II,III only  B) I only  C) I,III only  D) II only  E) III only
x=15.15y from which x = 15y + 15y/100 or x = 15y + 3y/20.   Since x and y are integers, 3y/20 must also be an integer. 3 is not divisible by 20, then y must be divisible by 20, and therefore, y/20 is an integer and 3y/20 is an integer which is a multiple of 3. From the given answers, only 15 and 3 are divisible by 3.   Answer I,III only
