Upon seeing this question, I immediately found that the answer was eighteen coins. the question says that one-quarter of coins are facing up, and when two coins are flipped, one-third of the coins is showing. this means that two coins are 1/6, and four coins are 1/4. added, it equals 1/3, which times six is eighteen.
