Where is the remaining $1?

Find out the answer to this question and you will surely be 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 took $5 off the bill and asked the waiter to give the customer $5 back.

Where is the other 1 USD? (Illustration)

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 are 2 USD in the waiter's pocket. Total: 72 + 2 = 74 USD

But the group originally paid $75. Where did the other $1 come from?
