If X, Y and Z are digits and 7XYZ is a 4-digit number that is divisible by 2, which of the following is a possible product of X, Y and Z?	Select:
A) 17
B) 42
C) 13
D) 27
E) 51
Key to this question is to remember the fact that a number divisible by 2 must end with 2 OR 0 (i.e Z).   If Z had to be 0, product should also be 0 regardless of X and Y.   The product is a multiple of 2. Only one answer choice meets the requirement.   Ans 42.
