A man places three coins in front of you – a bronze coin, a silver coin and a gold coin.
The man says “If you tell me a true statement, you will be given one of the coins. But if your statement proves to be false, you will be given nothing”.
What should you say to guarantee being given the gold coin?
If you haven’t tried to solve it, have a go now. For everyone else the answer is after the break.
You should say ‘You will not give me the bronze or the silver coin’. If this is true, you get the gold coin. It cannot be a lie, because if it were a lie, it would have to come true!
Did you solve it? Any other answers?
