you're just getting confused because of the way its worded.
they pay 25 for the meal and leave a 2 pounds tip
27
the waiter gives them a pound back each
30
-----
the sums you're doing are messed up cos you're tricking your own brain not to get it.
- T-Dawg0
bill total = 25$
25$ / 3 = 8.33$
tip total
2$ tip / 3 = 0.66$8.33$ + 0.66$ = 8.99$ ~ 9$
each man pays 8.99 (tip included)9*3 = 27$ bill & tip payed
3$ left for pockets

it is all just about the 2 pound tip, which needs to be divided by 3. that is all.
- Jimbo820
I know mathematically it all adds up (I did it last night with 30 coins and not one disapeared into thin air)
May question is WHY it doesn't work when it is read this way

slow day, Jimbo?
- T-Dawg0
The waiter has the £2 tip, which makes £29
--> this line is wrong
the £2 tip is part of the £27 paid by each man
- Jimbo820
OK ok ok. So say I was one of the 3 men. I hand over a tenner, I get a quid back. The same for T-Dawg adn McLeod. We've all paid in reality 9 pounds. The waiter, in reality, gets a two pound tip. Therefore;
I'm £9 down
T-Dawgs £9 down
McLeods £9 down
The waiters £2 upSo someone do the maths there. Cos I keep coming up with the same thing.

AAAAAGGGGGGHHHHHHH
Somebody kill me, I'll hire 3 people to kill me and pay them £25...
- 7point340
you've each paid 9
9*3 = 27
the bill was 25
25 +2 = 27there. you're done.

this was all covered in a thread discussing the same exact thing.
- Jimbo820
I understand that 7.34 but where does the confusion come from? It's not that I don't understand how it works, it's that I don't understand why it doesn't work the other way. I'm looking deeper into the mechanics of the question
- Look deeper, oh seeker. Think deeply, meditate slowly, do your sums with mastery. - BuddhaSkyPoo
- the 2 tip is included in your 9 dollars that is why7point34
- you've taken back the 3 bucks so it doesn't add up to 30 anymore it adds up to 277point34
- ok, so it has something to do with there being £3 left between the patrons and £2 for the waiterJimbo82
- therefore, by somehow subtracting the £2 from the £3 your left with the odd figure of 1 whichJimbo82
- affects the whole outcome of the sum. Just want a logical explanationJimbo82

I'm £9 down
T-Dawgs £9 down
McLeods £9 down
The waiters £2 up
--------------------------------...you've got this wrong. I would never hang out with you.

Just out of interest Jimbo...
You and I are sat in a pub, we each have a twenty pound note and between us we have one envelope - ordinary in every way, this is not a trick.
We both agree to place our twenty pound notes into the envelope and seal it.
We are now jointly invested in that envelope.
It is now time to bid for total ownership of that envelope by offering a fee to buy the other person out.
What will you offer me to own the envelope outright?
- Jimbo820
£40!
- T-Dawg0
you've been adding the tip twice
each man gives £10, gets back £1 --> everyone's paid £9
the waiter gets his £2 from the £27, (the other £25 covers the bill)
- SkyPoo0
You just paid me £40 to own an envelope that you already own £20 of anyway. I invested only £20, and I walk away with your buyout fee of £40.
The pleasure is all mine Jimbo. I like you more with every passing moment. Lets meet for drinks later.
