The Missing Dollar
Three men went to a motel. The motel manager said a room cost $30, so each man put up $10 and went to their room. A little while later the manager realised the room was only $25, so he sent the bellhop back to the three guys’ room with $5.
On the way to the room the bellhop couldn't figure out how to split the $5 between the three men, so he gave each one of them $1 and he kept the other $2.
This meant that the three men paid $9 each for the room for a total of $27. Add the $2 that the bellhop kept: $27 + $2 = $29.
Where did the other dollar go?
