Three friends go to a hotel. The man at the desk says the room is $30, each man pays $10 and go to the room.
A while later the clerk realizes the room is $25, so he sent the bellboy to the 3 guys room with $5.
On the way the bellboy cant figure out how to split $5 evenly between 3 guys, so he gave each of them $1 and kept the other 2 for himself.
This meant that the 3 guys paid $9 a piece, which is a total of $27, add the $2 that the bellboy kept equals $29.
WHERE IS THE OTHER DOLLAR?
