The Saturday girl gave me this today.

3 friends go into a shop. They see a PS game costing £30. They each pay £10 and leave the shop. The shop owner says to the assistant "That game was only £25. Here, run after them and give them £5 change." The assistant rushes out of the shop and while he's trying to catch up realises that £5 doesn't go equally between 3 people and pockets £2. He then give the friends £1 each. Ok so far? Right then this is the puzzle. If each person then only paid £9 and the assistant pocketed £2 where is the other £ ?

Each person also paid a 1/3 share of the £2 the assistant kept ( £0.6666666666) plus 1/3 of the £25 (£8.33333) which equals £9 (as near as damit!)

The thing still doesn't equate (to me, anyway :) )

Each person paid £10. 3 X £10 = £30

Each recieved back £1. 3 X £1 = £3

Therefore they actually paid £27.

The assistant kept £2.

£27 + £2 = £29.

Where is the other £1 ?

The shop owner gave the assistant £5 and kept £25 which was the correct price.  They all payed £9 each after getting the £1 back so that was £27 so the difference between the £27 that they paid and the £25 that the shop owner had was the £2 that the crook of an assistant pocketed. ;)

So that's how it works out :D Thought I was going daft ;)

OH ,..! please excuse me if you ever meet me........! I really are'nt that thick (honest)  but again its taken me all night to work this one out  :(   thankfully i think i was right . Well i had the same result anyway.  :D  mand x
