My sister phoned me today hoping i could answer this question, but i couldnt :? I dont want to cheat and google it.
Three people enjoy a meal at a Thai restaurant. The waiter brings the bill for £30 so each person pays £10.
Later the chef realises that the bill should have only been £25 so she sends the waiter back to the table with £5. The waiter was not very good at Maths and could not figure out how to divide the £5 so he gave each person a £1 and kept £2 for himself.
So….the three people have paid £9 each for the meal.
9×3=27The waiter kept £2
27+2 = £29What happened to the other pound? Does this make sense?

omg, answer damn you! It’s doing my tiny brain in! :)

There isn’t a missing pound, it’s a linguistic puzzle rather than a arithmetical puzzle.
They’ve actually paid £8.3333333 for their meal = £25 plus a £2 tip for the waiter which comes to £27 giving them each £1 change which comes to £30.
It’s an oldie but a goodie :wink: :lol:
(refrains from saying “a bit like me…”)

:idea: hehe
you’re right to be confused, Mrs T
Jen didn’t get it right, at least not in the arithmetic.
Each customer paid £10. They recevied back £1 as part of their over-payment. That means that each customer ended up paying £9 for the meal. The puzzle remains, so that certy is rightly confused.
Jen will have to explain it more clearly, as she has added aritmetical confusion to create a linguistic puzzle all of her own lol
no offence meant, Jen. Biut over to you, mah dear
27 April, 2012 at 8:04 am #494475Meal = £25 Tip = £2
Add the two together = £27
They paid £30 so £30 – £27 = £3
Therefore each gets £1 back
The £2 the waiter kept should be added to the £25 for the meal so the total cost of the meal was £27. The change is the other £3
It is not £27 + £2 but £27 + £3

You are right to be confused Mrs T, not about Jen’s answer, but about the original question.
Permit me to suck the joy out of the thread by explaining.
It asks about a pound which is not actually missing. A bit like asking what happened to the inches which would have made me 6 ft tall, you can add in any other factors and repeat the question as often as you like, but nothing’s actually missing.
See J’s calculation – they paid out £27 which is £9 x 3.
£25 for the meal. One third of £25 is £8 6s 8d, or eight and one third pounds (at least it was when this puzzle was invented).
£2 went to the waiter. That is the end of it.
The figure of £29 is only arrived at by adding in the waiter’s ‘tip’ twice.
So Jen is right and so are you because the question is meant to confuse.
