Re: OVERCROWDED JAIL

If anyone is interested, here are two similar puzzles. I thought I might as well add them here rather than start new topics and clutter up the message boards. The first one is medium difficulty, the second one is harder. 1. 10 prisoners are told they will be lined up so they'll only be able to see t...

Pi litres

This is a problem I heard on the radio a few years ago, and this isn't one that's particularly well known. There are probably many correct solutions, but there is one that is particularly clever. You have an infinite source of water, a bowl that can hold an indefinite amount of water, but at least 6...
