interesting but confusing

Three friends went to a hotel. The bill was Rs 75/-

Each one contributed Rs.25/-.

The waiter took the bill to the cashier.

The cashier was happy & decided to give them a discount of Rs.5/- & asked the waiter to return them Rs.5/-.

Now the waiter was confused. How to distribute Rs 5 among 3 persons?

He kept Rs 2 in his pocket & gave one rupee to each one of the 3 persons.

So initially each one had contributed Rs.25. Now as they are given 1 rupee back, their contribution reduces to Rs 24.

They all contributed Rs 24 -- that is 24x3=72 & 2 rupees are in the waiters pocket.

The total becomes 74. But they had paid Rs 75.

Where is the remaining 1 rupee?.

Check your pocket for 1 Rupee.

I do not know the answer. If you have solved this please let me know where is that one rupee.

Eat something and try again.
