Solution and full explanation provided here:  P5″ logic question is actually a Math Olympiad question for Sec 3 and 4 students.  I got close but didn't solved the whole thing.  My error was that I didn't read the problem closely enough.

If it made it to In Progress, it must be viral. I love these kinds of problems, because what you don't know is as important as what you do. A life long lesson. This is a good one, but I have learned to read carefully.
