3 men pay 10 dollars each for a 30 dollar hotel room.the management realizes their was a special of 25 dollars for the room.he gives the bellboy 5 dollars to refund them. the bellboy thinks okay i cant divide5 dollars between the 3 guests so i will give them 1 dollae each back and pockets 2 dollars so each man effectively pays 9 dollars each.question 10 each paid less 1 dollar = 9dollars.3 men times 9 =27 2 in bellboys pocket.wheres the other dollar gone.
