c9Three people check into a hotel. They pay $300 to the manager and go to their room.
The manager suddenly remembers that the room rate is $250 and gives $50 to the bellboy to return to the people.
On the way to the room the bellboy reasons that $50 would be difficult to share among three people so he pockets $20 and gives $10 to each person.
Now each person paid $100 and got back $10. So they paid $90 each, totalling $270. The bellboy has $20, totalling $290.
Where is the missing $10?
