Three friends went to a hotel. The bill was Rs $75 Each one contributed $25. The waiter took the bill to the cashier. The cashier was happy & decided to give them a discount of $5 and asked the waiter to return them $5.
Now the waiter was confused. How to distribute $5 among 3 persons?
He kept $2 in his pocket and gave $1 to each one of the 3 persons. So initially each one had contributed $25. Now as they are Given $1 back, their contribution reduces to $24. They all contributed $24. ie 24x3=72 and 2 dollars are in the waiters pocket. The total becomes $74. But they had paid $75. Where is the remaining $1?

We need to subtract the waiters RS 2 from Rs 72 rather adding it because its a 5rs discount so it must be subtracted.
Initially the bill was Rs 75 so after Rs 5 discount the cost became RS 70.
