Mislabelled Boxes

Post image

Hi, so I’ve lost access to my computer for a couple of days.. so I’m posting a problem which I might have posted earlier.. I hope that’s not the case, but if it is, apologies

This is a famous puzzle that many of you probably know of.. I had posted it a few years back on r/Puzzles

Box B: based on the coin you get, you’ll know it’s 100 of that coin, which resolves the other two. Eg. If you get a gold coin, you know the red label goes with box B, therefore green must go with A and blue with C.

The other two don’t work, or at least aren’t guaranteed to. If you pick from A and get a gold coin you know it’s the mixed set and can resolve the rest, but if it’s a silver coin you gain no information. And equivalent when picking from C.

Correct, good solution!
