Finding the answer to this question will surely make you a very smart person.


The problem is as follows: Three friends go to a restaurant for dinner. The bill for this meal is $75, each person contributes $25.

The waiter brought the bill and money to the cashier. Since the restaurant was having a promotion, the cashier reduced the bill by $5 and asked the waiter to give the customer $5 back.

The waiter was confused: How to divide 5 USD among 3 people? He decided to keep 2 USD and give each group of guests 1 USD.

The question is: Initially each person contributed 25 USD, now they are given back 1 USD, that is each person contributed 24 USD. All 3 people contributed 24 USD, so: 24 x 3 = 72 USD. In addition, there is 2 USD in the waiter's pocket. Total: 72 + 2 = 74 USD

But the group originally paid $75. So where is the other $1?
