Hi, 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 & gave them a discount of Rs.5/- & the waiter returned them Rs.5/-. Out of that, they took one rupee each and gave the waiter a tip of Rs 2.. So initially each one had contributed Rs.25. Now as they got 1 rupee back, their contribution reduces to Rs 24. They all contributed a total of 24x3=72 & 2 rupees are in the waiter's pocket. The total becomes 74. But they Had paid Rs 75. Where is the remaining 1 rupee?????????

Please calculate it this way. They paid 70 Rupees in reality. They got 3 rupees back and gave two rupees to waiter. Thus the total comes out to be 75 Rupees. There is a factor of illusion in the question in the way u r presenting it. You will find this illusion in many mathematical problems. So to get the right answer, it is better to avoid the illusionary factor.
