Wher did the dollar go?

Once,three men went to a restaurant.Their bill was $25 and each of them paid $10 each. The waiter took the money to the cashier and brought back $5. Since the money couldn't be shared equally among them,he gave $1 to each man and took $2 as a tip. Now, each man paid 9 dollars, which takes 27 plus two (from waiter) = $29. $30-$29=$1.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

It is true that each person paid $9. So, totally they paid $27 out which $25 was taken by the hotel manager ( or whoever takes the money ) and $2 was taken by the waiter. $2 + $25 = $27. There is no mystery at all. Adding up the money gained by the waiter and the money paid by the people gives nothing but thier difference gives you the money taken by the hotel.
