Three couples book into a hotel. Thats £30 total says the receptionist. The couples hand over their £10 each and go to their rooms. The manager arrives and tells the receptionist that there is a special where 3 rooms are £25 so gave him £5 to take back. He was not sure how to divide the £5 between the 3 couples so decided to keep £2 for himself and handed each couple £1.
So that means each couple paid £9
3 x £9 = £27 plus the £2 that the receptionist kept is £29
Where has the missing £1 gone
