Riddle AnswerThe Missing Dollar
Three men go to stay at a hotel and they are charged $30 for the room.
They split the cost with ten dollars each.
Later the manager finds out that the rate is $25 and gives the bellboy $5 to return to the guests. On the way to the room the bellboy reasons that $5 would be difficult to split among three people so he pockets $2 and gives $1 to each person.
Now each person paid $10 and got back $1. So they paid $9 each, totalling $27. The bellboy has another $2, adding up to $29. Where is the missing dollar?
