A maths question?

Question

Three people are at a restaurant having a meal. Their meal is £30 so they pay £10 each. The waiter brings the money to the chef, the chef says the meal is only £25. So the waiter heads back to the customers and decides he will keep £2 and give each customer £1. How much did they pay each? Lol dunno if i asked this right ;S

To all the people wanting an answer, i don't really know it, a friend asked me this question and i can't figure it out all. He said it can't be answered, and another friend said it proves mathematics wrong lol. Anyway i think it's still £10 each as they "kinda" paid the waiter :S

Lol ignore my theory above totally balls'd it up, had another look at what i said lol.

Answer 1

Cost for meal 30.00
adjusted cost 25.00
cost of waiter 2.00
refund to customer 3.00

consider this as the cost:
25.00 meal
2.00 waiter
------------
27.00 total cost
3.00 refund
----------------
30.00 original amount

Even though the three dollars was paid to themselves, it still has to be treated as an expence because it was still paid out of the original 30.00.

Another way to see it is:

25.00 meal
2.00 waiter
==========
27.00 which leaves 3.00 for the refund

--------------------------------------------------------------------

The OP is stating they paid 30, which is 10.00 each.
cost was down to 9.00 after refund, which means they paid 27.00
plus two for the waiter makes 29.00 this is in error
because the 27.00 (9*3) includes the waiter fee, not on top of this. This allows the 3.00 refund for themselves
That 9.00 each included everything else other than themselves

Answer 2

They each paid £9.00 because the waiter ripped them off. What they should have done was be charged £25 for the three meals. That would equate to 25 divided by 3 ... well, 3 x 8 is 24 so that would be £8.33.9999999999 each

well that is my guess... now tell me the catch!

Oh I See... there is supposed to be a missing £1

I suggest calculating it forward not backwards.... they Paid £10 .. they got £1 back. The £1 which they got back and the waiters self-induced tip of £2 all came out of the original £30. So there is no missing £1.

Dan O : the £2 for the waiter was included in the £27 not to be added on. 29 doesn't ever enter the equation.

Bill:

Food : £25
Tip: £2
Total: £27

Cash: £30
Change £3

Answer 3

Many have been confused by this conundrum. The problem is that you're adding up the wrong numbers. First, each party ended up paying £27 - but this £27 is the £25 bill and the £2 the waiter kept. So, there's no need to add on this £2 again. What you need to add on is the £3 change. £27 paid (£25 bill + £2 taken) + £3 change = £30: each customer paid £9 and had £1 change.

Answer 4

Each customer paid £9 each, £27 total paid.
The Chef had £25, the waiter £2, £27 received.
What's the problem, it balances, so no problem.

Answer 5

9 x3=27 +1+1+1=30
they paid 9 pounds each and they took 1 pound back thats 10 pounds.
the food was 25 plus 2 for the waiter =27

Answer 6

They pay 9 pounds each for a 25 pound meal. Which leaves 2 pound left over for the waiter. Your just thinking about it the wrong way.

Answer 7

£9

Answer 8

I`am a chef and if the waiter brought me the money for the meal it would make my day :o). Anyway i work it out at £9.

Answer 9

♥ ♥ 9 plus 1/3 of what the waiter kept ♥ ♥

Answer 10

the each paid £8.33..... coz they meal was 25 divided by 3 it equals to 8.333.. originally they paid 30 but 3pound was given back to them and £2 was taken by the waiter so 8.333..times 3 will be equal to 25 plus 3£ which equals to 28 plus 2£ the waiter took wil total to £30 so i believe they paid 25+2=27 which when divided by 3=9 they each paid £9
