Classic Riddle... Try it?
3 men want to buy a room in a hotel for the night. The bellboy tells them it'll be $10 each so they pay him. The cashier tells the bellboy that the room only costed $25 and the bellboy needed to refund the men $5. The bellboy knew that dividing $5 among 3 people wouldn't work so he pocketed $2 for himself and gave each of the men $1 back each.
The men payed $9 each for their room after the rebate and the bellboy pocketed $2.
9+9+9+2=29
Where'd the other $1 go?
I will give an explaination so try your hardest.
