Random puzzle: Thirteen coins
There are 13 exactly same looking coins. One of them has slightly different weight than the others – we don’t know if it is heavier or lighter. Can you tell in 3 scalings which one it is using even arm balance?
If this riddle by any chance seemed too easy for you, try 40 coins in 4 scalings – the principal is the same.
