Three men in a cafe order a meal the total cost of which is Rs1500. They each contribute Rs500. The waiter takes the money to the chef who recognizes the three as friends and asks the waiter to return Rs500 to the men. The waiter is not only poor at mathematics but dishonest and instead of going to the trouble of splitting the Rs500 between the three he simply gives them Rs100 each and pockets the remaining Rs200 for himself. Now, each of the men effectively paid Rs400, the total paid is therefore Rs1200. Add the Rs200 in the waiters pocket and this comes to Rs1400.....Where has the other rs100 gone from the original rs1500?

The actual amount paid by the three men here is Rs 1200 as each of them contributed Rs 400. Out of this money the chef has taken Rs 1000 and the waiter pocketed Rs 200. Thus the calculation matches.
