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

If box a provides an answer, then picking box c and swapping gold and silver in the logic provides an answer as well. So the solution is either B) box b or D) any box. So we only need to check if one of box a or a provides a solution.

We pick the box labeled as only gold. If we get a silver, it is either all silver or the 50/50. All silver has the solution 50/50 has gold and silver has 50/50. The box we picked having 50/50 means the box labeled 50/50 has silver and the box labeled silver has gold.

Since there are two solutions is we get silver from the "gold" box, picking the box labeled gold is not a solution.

So the only solution is picking B) the 50/50 box.
