A merchant has four locked chests labeled 1 through 4, containing gold, silver, bronze, and copper coins respectively (one metal per chest). He posts four clues on the wall: Chest 1 is not gold. Chest 2 contains silver. Chest 3 is not copper. Chest 4 is bronze. If exactly one of these four statements is true, which chest contains the gold?
Chest 1
Test each chest as the location of gold while evaluating the statements. If Chest 1 has the gold, Statement 1 is false (it is gold), Statement 2 is false (Chest 2 has silver, but silver is elsewhere), Statement 3 is true (Chest 3 is not copper, it's silver), Statement 4 is false (Chest 4 is bronze, but bronze is elsewhere). This gives exactly one true statement (Chest 3).
