How are you at simple mathematics? Then solve this :-
Three salesmen had just left a sales conference and decided to go to a nearby hotel for the night before returning home. At the hotel the receptionist said there was only one room left, it had room for 3 and it was £30 for the night. So they each paid £10, which comes to £30. OK so far?
A little while later the receptionist realised she had made a mistake. The room was not £30, it was £25. Got that ? She summoned the bell boy to take the £5 change to the salesmen. On the way to their room the bell boy thought, if I give them £3 change they'll be happy, and I'll keep £2 (£3+£2 = £5). Got that so far ?
Now the tricky bit.
The three salesmen had got £3 change. So they had only paid £9 each. OK
So 3 x £9 = £27, add the bellboys £2, which = £29. Who's nicked £1.
