Nice one, but based on a false premise. We naturally think that money to the restaurant must equal money in = £30, but it doesn't follow. Once they've got their £1 back the amount 'in the system' is £27.

At the start the customers have £30, restaurant nothing - balance.
After payment, restaurant has £25, customer A has £5 - balance.
He pays the tip and distributes £1 each to mates.
Customers have £3 total, tip jar has £2, restaurant has £25 - balance.

Each customer has paid £9 net, - in the proportion 2/27 to the tip jar, 25/27 to the restaurant - £27 total plus £3 to take home. Balance, no missing quid.

Another equivalent way of thinking of it would be if the customers all contributed £9 in pound coins - £25 goes to the restaurant £2 remainder to the tip jar, same transaction, no missing £1.

Thats very good. You really should try your hand at one of the AGW threads - I think you would be good at it.

Three friends go to a restaurant, they have a tenner each.

One of them takes the thirty pounds to the till and finds the bill is £25

he puts 2 quid on the table as a tip, and gives himself and the others a pound

so they each paid 9 quid = £27. plus a 2 pound tip = £29


where did the other pound go ?

or drumroll..... is .9999(recurring) = 1

.9999… is indeed equal to 1.

I think I've got it now.

Deano, Mickey and Spazzy Steve all agree to chip in a grand to buy a bag of coke that one of Deano's mates says is coming in from Rotterdam, hidden in a load of bathroom fittings.

Deano robs a Post office on pensions day, Mickey sells his old mum's ford fiesta and Spazzy Steve claims housing benefit for a bogus Romanian family.

When they get down the docks to make the buy, they all get pinched by the rozzers.

They each get 9 years for the deal but Deano gets an extra two cos of his previous.

Question: Who really has the coke and how long is it before Mickey is doing Deano's missus?

That lot reminds me of one of my favourite lines from Trainspotting:

Two kilos, what's that, about 10 years?

Mikey Forrester, Russian sailors? What the f*** are you boys on?

[Zippy]

ok, here is another one.

no scouser jokes, or youse are barred.

let x = .9999 recurring

therefore 10x = 9.9999 recurring

subtract x from each side
9x = 9.9999(recurring) -x

therefore, as x = .9999(recurring)
9x = 9

divide both sides by 9
x = 1


so. is x = to .9999(recurring) or is x = 1

or drumroll..... is .9999(recurring) = 1

Now you're just being bad at sums. Did Ken Dodd do your tax return? :

I'm still struggling with a few things.

1) Are we supposed to believe that a scouser would spend almost a tenner on lunch.
2) Ditto for leaving a tip
3) Also for coming clean about the cost reduction
and finally
4) The most outlandish bit is that they would trust one of them to take the £30 cash and walk towards the exit without doing a runner.

Nope, something's not right.

Who nicked the car to get home?

where did the other pound go ?

They each paid 9 quid, but that included the 2 pound tip, because the 2 pounds came out of the 3 * 9 quid that they paid.
So adding on the 2 pound tip implies that they made a second 2 pound tip over the top of the one what they had already made. Which would make for a happy waiter, but £2 less to put into the pub fruit machine that they go to next, a little sozzled.

its hyperthetical. obv.

[EternalOptimist]

Basically the question is wrong. As one of the friends was a scouser, the correct puzzle should be,


Three friends go to a restaurant, they have a tenner each.
One of them takes the thirty pounds to the till and finds the bill is £25
he puts 2 quid on the table as a tip, and gives himself and the others a pound
so they each paid 9 quid = £27. plus a 2 pound tip = £29

Who stole the charity box?

I understand why you are upset. It was bad news over the weekend, learning that you will have to power up your electricals before flying to the USA. If your vibrating butt plug doesn't get through security, you would be devastated

You're mixing cost and cash.
