Three men want to rent a room (I don't know why, don't ask). The manager says it costs $30. They each pay $10 and go up to the room. The manager finds out he overcharged them. The room is only $25. He sends the bell-boy up with $5. The bell boy wonders how they will split $5 between three men, so he pockets $2 and gives them $3.
My question is...
Three men spend $9, plus the $2 the bell-boy took equalls $29
Where did the other dollar go?
