3 friends went to a hotel and paid 30 dollars for a room at 10 per person.
Then Hotel manager realise that he over charge these 3 people 5 dollars as the cost was only 25.
Then he asked waiter to give 5 dollars back to these people.
Waiter kept 2 dollars to him help as it would be easy to pay 1 dollar each for 3 people and he did it.
So one man got 1 dollar each back each man paid 9 dollars
That means 9 * 3 (people) = 27 + waiter 2 = $29
So what happened to the other dollar?
