One rich man had a cross and there were jewels on it. When he counted them from down to up (this was his habit), then he got nine. But once one jewel fell off and the man took the cross to the jeweller for repair.
Answer: When he got the cross back, he counted like always from down to up and got nine. But the jeweller was greedy and took two jewels. The man, however, didnt notice anything.
