PUZZLE

Hi guys,


I don't whether this puzzle or question asked before in boddunan.

Here is the question 3 persons going to hotel had food for Rs.25 and they all gave Rs.10 each , so the total amount is Rs.30. The waiter gave balance 1 coin * 5 i.e 5 rupee balance. So they decided to take Re.1 each ,so all three gave Rs.9 each 3*9=27.The balance from the waiter is now RS.2. 27+2=29. But they paid Rs.30. Where does the Re.1 gone.

I got this info from Discovery Channel.So don't blame that i copied .
