Title: How good is your Maths?
Post by: zirk on 24 October 2009, 14:32:29
Three guys go in to a restaurant to have something to eat, finish their food then ask for the Bill.
Waiter brings the Bill leaves it on the table and walks away, The Bill comes to £25.
Each Guy produces a £10 note and puts their Note with the Bill (£30).
The Waiter picks up the money takes it to the Till and brings back their change, 5 x £1 coins (£5).
The three Guys decide to share the cost of the food between them and leave a tip for the waiter. They each pick up a £1 coin and leave a £2 tip for the waiter.
The three Guys leave the restaurant and the Waiter pockets the £2.

Now if each of the three Guys has put in £10 each and have each taken £1 back that means that they have each paid £9 for their meal (£10 - £1 is £9) and the Waiters happy with his 2 quid tip, correct so far.

Now do the Maths, If each of the Guy’s have paid £9 for their meal, then 3 x £9 is £27, plus the £2 tip equates to £29 !, where’s the other pound gone?

the bill = £25
tip = £2
total = £27

three guys take £1 each = £30

So if you give me £10 and I give you £1 back, how much have you spent?
