If you know the answer.. give those that don't know a chance to work their brain..
3 men went to a hotel and asked the clerk how much a room would be for the night. The clerk said, "That will be $10 each." The men paid for the room and a while later the clerk decided that he charged $5.00 too much. He told the bellhop to return the $5 to the men. As the bellhop was headed for their room he couldn't figure out how he would divide the $5 between the 3 men, so he decides to keep $2 so he could just give each man back $1.
Sooo.. if he gave each man back $1, that means that each of them just paid $9 for the room which = $27
The bellhop kept $2.. that makes $29... Where did the other dollar go?
