If I, J and K are digits and 9IJK is a 4-digit number that is divisible by 5, which of the following is a possible product of I, J and K?
Choose the correct choice from the following options:
A) 23
B) 48
C) 72
D) 25
E) 94
Key to this question is to remember the fact that a number divisible by 5 must end with 5 OR 0 (i.e K).   If K had to be 0, product should also be 0 regardless of I and J.   The product is a multiple of 5. Only one answer choice meets the requirement.   Ans 25.
