## The missing dollar

Three people check into a hotel room. The bill is \$30 so they each pay \$10. After they go to the room, the hotel's cashier realizes that the bill should have only been \$25. So he gives \$5 to the bellhop and tells him to return the money to the guests. The bellhop notices that \$5 can't be split evenly between the three guests, so he keeps \$2 for himself and then gives the other \$3 to the guests. Now the guests, with their dollars back, have each paid \$9 for a total of \$27. And the bellhop has pocketed \$2. So there is \$27 + \$2 = \$29 accounted for. But the guests originally paid \$30. What happened to the other dollar?
This riddle is just an example of misdirection. It is actually nonsensical to add \$27 + \$2, because the \$27 that has been paid includes the \$2 the bellhop made. The correct math is to say that the guests paid \$27, and the bellhop took \$2, which, if given back to the guests, would bring them to their correct payment of \$27 - \$2 = \$25.
