Mind bender:

3 men go to a motel to get a room. The desk clerk tells them the room will cost $30. Each man pays $10. Later the desk clerk realizes he made a mistake. The room should have only cost the 3 men $25 total. He gives the bellboy 5 $1 bills and tells him to refund it to the men. On the way to the mens room the bellboy is confused. He doesn't know how to evenly divide $5 among 3 men. Here's what he does. He gives each man $1 and keeps the other $2 for himself.
This now means each man only paid $9 for the room. $9x3=$27 plus the $2 dollars the bellboy kept = $29. Where is the other $1? Have fun and don't be mad at me.

Hint:Everything you need to solve this problem is given to you in the story. No. it doesn't matter what the men were going to do with the room!
