Steps/Work
This question asks what IS...(the answer), so we know that the answer will be definite. As such, we can TEST VALUES to quickly get the solution.
We're told that P and Q are POSITIVE INTEGERS and P = 10Q - 5. We're asked for the REMAINDER when P is divided by 5.
IF....
Q = 1
P = 5
5/5 = 1 remainder 0
Final Answer:
A
