Today's Question - You have nine seemingly identical rare coins. But you are told one coin is short weight. How can you find the light coin in two weighings? (You only have a balance scale.) NO COMMENTS MONDAY Cashin’s Comments January 27, 2017 Page 3 of 3

Reveal Answer Answer - Finding the short weight coin - divide the 9 coins into 3 sets of 3 coins (A, B, C). Weigh A versus B. If they balance, the short coin is in "C" (if they don\'t balance, the problem coin is in the lighter set). Having identified the problem set, weigh two of those coins. If they balance, it\'s the third coin.
