The copper medal is called Zz. It is named after the number zero. The six gold medals are named A, B, F, H, K, and L, respectively, and the names of the gold medals are written in capital letters. The six silver medals are named c, d, e, g, i, and j, respectively, and the names of the silver medals are written in lower case. Each copper, gold, and silver medal has a "number". The numbers are as follows:
00 Zz 01 A 02 B 03 c 04 d 05 e 06 F 07 g 08 H 09 i 10 j 11 K 12 L
Three measurements are made with the balance scale as follows: - 1st time eFgK on the left pan, HijL on the right pan. - 2nd time BcdK on the left pan, eFgL on the right pan. - 3rd time AdgH on the left pan, BejK on the right pan.
To convert the results of the three weighings into an answer to the puzzle, take the first weighing to have a value of +9 (if the left side is lighter) or -9 (if the right side is lighter). The second weighing would have a value of +3 or -3, and the third weighing would have a value of +1 or -1. Add the results. The absolute value of the answer indicates which medal is counterfeit by matching it with its number.】 |
