Three friends went to a hotel. The bill was Rs $75, Each one of them contributed $25. The waiter took the bill to the cashier. For some reason 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. i.e. 24×3=72 and 2 dollors are in the waiter’s pocket.The total becomes $74. But they had paid $75.
Where is the remaining $1?
Total given by customers = 3*24 = 72 = 70(with cashier) + 2 (with waiter).
in other words $75 earlier given by customer are distributed as
70(with cashier) + 2(with waiter) + 3(one dollar with each customer).
