Miraculous Solution To HARD Test Problem

This one stumped me! This problem is part of the AIME, a qualifying test for the US Mathematical Olympiad team. The talented students who take the AIME only average about 20 percent--it's a hard test! Plus no calculators are allowed. Can you figure out this problem from the 1987 test? Learn the trick which results in a miraculous solution. Thanks to all patrons! Special thanks this month to: Michael Anvari, Shrihari Puranik, Richard Ohnemus, Kyle.
