Here is another riddle,
An old man has two sons and he is dying, he must inherit his money in one of them but he cannot choose, the money he has decided should not be split equally but given to only one. He gives them a challenge, the owner of the camel which crosses the finish line last is the winner. The boys wandered on their camels aimlessly for days then they asked a wise man for help. The two boys quickly jumped on eachothers camels and dashed towards the finish line.
What did the wise man say?
I'll give you a hint, I thought it was that the old man was dying but that is not it.
