Tom, Dick, and Harry each paid 10 dollars for a room at the hotel. When the manager found out, he told the desk clerk that Tom, Dick, and Harry were friends of his and they should be charged only $25.
The desk clerk gave the bell boy $5 and told him to return it to Tom, Dick and Harry. The bell boy, however, decided to give them only three dollars and keep two for himself.
If Tom, Dick and Harry each received $1 back, then that means they only paid $27 for the room. With the $2 the bell boy has in his pocket, the total is $29.
What happened to the missing dollar?
