I'm going to have to take this riddle bait. My solution:
Move 1: weigh 6 coins vs 6 coins. Isolate the heavier set for the next move.
Move 2: weigh 3 coins vs 3 coins. Isolate the heavier set for the next move.
Move 3: weigh any two of the 3 remaining coins. If one is heavier, that is the counterfeit. Otherwise (if coins are equal in weight) the remaining coin is counterfeit.
- ythn 8y agoYou failed because: > One is counterfeit and is either heavier or lighter It turned out the counterfeit was lighter and you discarded it after the first weighing.
