If X and Y are digits and 8XY is a 3-digit number that is divisible by 2, which of the following is a possible product of X and Y? Choose the correct choice from the following answers
A) 15 B) 31 C) 12 D) 27 E) 91
Key to this question is to remember the fact that a number divisible by 2 must end with even OR 0 (i.e Y).   If Y had to be 0, product should also be 0 regardless of X.   Otherwise, product is a multiple of 2. Only one answer choice meets the requirement.   Ans 12.
