Three friends go to a restaurant and the bill comes to $30. They each contribute $10, but the waiter realizes there was a mistake and the bill should have been $25. So, the waiter gives $5 to the cashier to return to the friends.
The three friends each take $1, and then they give the remaining $2 to the waiter as a tip.
Now, each friend has paid $9 (since they took $1 back from their $10).
So, they paid 3 × $9 = $27, and the waiter got $2. But $27 + $2 = $29! Where is the missing dollar?

What is There is no missing dollar! The riddle is a trick. The $27 includes the $2 tip, so you don’t need to add that $2 again. The $27 is already the total amount they paid.
