### Annoying question

**Thu Oct 28, 2010 8:11 pm**Okay, this one baffles many people, and I'm not entirely sure I can remember the answer but here goes...

Three friends check into a hotel. The room is Â£30 so they spilt it and pay Â£10 each. The person at the door takes their money to the manager who informs him that today there is a discount and the room only costs Â£25. So the person at the door goes back to the room, gives each person Â£1 back and then pockets the last Â£2 for themselves.

So here's the tricky bit - If each person paid Â£10 and got Â£1 back (Â£9 each) and the person at the door pocketed the Â£2 then that makes a total of Â£29 (9+9+9+2)

So where did the other pound go?
