The Riddle

While sitting round the dinner table telling stories tonight, my cousin relayed an intriguing one. Now I should mention that this week marks the celebration of yet another family member (my cousin) who along with his girlfriend, is graduating from Harvard University. It was at my aunt’s house in honor of this special occasion, and in the presence of my immediate and extended family, my cousin’s girlfriend and her family that this story transpired.

When my cousin's girlfriend was in the 5th grade, she came upon an extra credit question, a riddle actually, that she could not solve. This was it:

10 P on Z in S

For the last 15 years since that fateful day in elementary school when she first tackled the riddle, this problem has remained her own personal unsolved mystery. Quite miraculously, and seeminly out of the clear blue, she recently she awoke in the middle of the night – the answer had come to her!

This evening, my cousin relayed what the riddle was, and his father (my uncle) puzzled over it and within 3 hours he too had solved it. Now it is your turn, and I will pose a challenge to all who read this and give you a chance to solve it too. Please post, or email your answer.
