Question 930550: Three men dine in a restaurant. The bill is RM30 and each man hands the waiter RM10. Later, the cashier realizes that there has been a mistake, the bill is RM25. The waiter is asked to return the men RM5. But it suddenly occurs to him that RM5 will be hard to divide among three people, so he keeps RM2 for himself and returns each of the men RM1. This means the men pay RM9 each, making it a total of RM27, and plus the Rm2 the waiter keeps, the final amount is RM29. Where has the extra RM1 gone? Or are we forced to conclude that RM30 = RM29?

Golden rule! Keep track of the money. The waiter puts RM30 in the cash register. He then takes RM5 out of the cash register leaving RM25 in the cash register. The waiter takes RM2 of the RM5 leaving RM3 to distribute to the three men. Now where are the RM's?? RM25 in the cash register; RM2 in the waiters pocket and RM3 distributed to the three men which adds up to RM30 as it should. From the restaurant's viewpoint, the three men paid RM25--not RM27.
