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 24×3=72 & 2 rupees are in the waiters pocket.
