Yeah it's just misleading math on OP's part.

You have made a mistake. The waiter's £2 is part of the £27 cost. It should be: £27 + £3 returned to diners = £30, no £1 missing.

It's not a mistake, it is purposely worded wrong. That's why it's a brain teaser. A very old one with many variations.

because if you read the previous posts, you'll realise it's just wrong..

they pay £9 each, £27, and the waiter takes 2 of those £27, leaving £25 in the till.

I don't understand why its so funny or wrong, as here you are talking semantics. The cost to each person of the actual bill is £8.33. The 67p each is the extra money paid to the waiter. My way of showing it was simply displaying that the food that they paid for is worth £25, the other £2 went into the waiters pocket.

How is that wrong at all?

ah yes, for the food that is true. I just misunderstood as originally you didn't say just for the food. sry.

The logic and maths is correct in showing where the total £30 goes, just a slightly more complicated way of showing it to what is needed to explain why there is no missing £1. I think the other poster just hasn't realised there are other ways to show it.

Because each of the guys don't pay £9 each (i.e. £10-1), as the £2 that the waiter takes from the bill is deducted from the bill as well. So each person actually pays £10- £1.67 = £8.33 each £8.33x3 ~= £25.


Edit: The £8.33 is the contribution towards the £25 bill. The extra 67p each that they pay is paid to the waiter.

Each person is out of pocket £9, they paid £8.33 to the bill and £.67 to the waiter, making his two pounds.

You did way more math than was necessary.

This is so stupid.

I don't know anybody who can't figure this out within 10 seconds.
