This puzzle is driving me mad - help!

dark crystal

Ok, I've been trying to work this b'stard out for ages now and just can't do it. It looks simple enough, but I can't work it out at all.

Can someone tell me the solution PLEASE?!

You see a €97 dress, but you don't have any cash, so you borrow €50 from mum and €50 from dad = €100.

You buy the dress and get €3 change, so you decide to give mum back €1 and dad back €1 and keep the other €1 for yourself.

You now owe mum €49 and dad €49 = €98, plus the €1 you kept = €99.

So where's the other €1?

:mad:

its a math quirk

its the way you process the wording that doesn't make sense

if you do out the equation it would make sense

97 is the cost
1 change for you
1 change for your ma
1 change for your da

100 total

in other words you owe each parent 50 quid and used 48.50 of that which is the 97, so when you give back another dollar to each parent that leads to 99 and you have the extra one then

Crossdresser?

Gee_G

That's very annoying! I came across that on Facebook or something before and can't figure it out!

What colour is the dress?

You take the dress back, get a refund, then repay, if its 100 always get it down to 99.

Adding the €1 to the €98 is the logical flaw. Thats yours you don't owe it so why add it. The €2 you paid is part of the debt not the €1.

You're looking at it the wrong way. You don't have a euro yourself, you still owe it to you parents as it is their change, not yours, so you they get 50 cent of it each. So instead of adding it to the 98 euro you still owe them, you subtract it, so you owe them 48.50 each. 2 x 48.50 = 97 euro.

The mistake is in adding the 1 euro to the 98 instead of taking it away, it's a logic problem.

Get a scratchcard with the 3 quid change and give it to Mam and Dad in lieu of the money you owe them. Job done!

It is kinda like, what can you put into a glass that you can not take out of it.

After giving the parents each €1 back, you owe €49 + 49 = €98, and have €1 left. If you were to give that last €1 to your mum, you would owe a total of €97, for which you got a €97 dress. So it balances out correctly. The problem wording confuses what you have with what you owe. :cool:

VEN

you spent the other €1, its now part of the €97 dress. give back that €1 to your parents whenever you get it along with one you kept, you will then owe them nil.

no?

akura

When you keep the euro you owe your parents 98 so you still owe them a euro each

Aaah, I see what you mean! When you work it out that way it makes sense alright.

It's just an upside down way of explaining a pretty simple equation.

God, that hurt my brain.

namloc1980

You had €100
You spent €97
You have €3 left over

€97 + €1 (given to father) = €98
€98 + €1 (given to mother) = €99
€99 + €1 (which you kept) = €100

Let's try the same logic with a cheaper dress...

You see a €1 dress, but you don't have any cash, so you borrow €50 from mum and €50 from dad = €100.

You buy the dress and get €99 change, so you decide to give mum back €1 and dad back €1 and keep the other €97 for yourself.

You now owe mum €49 and dad €49 = €98, plus the €97 you kept = €195.

So where's all this f@!#ing money coming from?

Next one please that kept me entertained for awhile

It's the same principle as the change scam. Very easy to catch someone out at a busy till.

Dwork

Emigrate to Aus and change your name. Feck them and their alleged "debt". Keep the €1. Hah, suckers.

The_Gatsby

You borrowed €100. You've paid back €49.50 to each parent by giving them half of the 97 plus that €1 each. The €1 you have left over is actually still owed to your parents, 50 cent to each of them.

If you only gave your father back a euro you would owe 99euro but have two euro change=101 euro,I'd go for that.

I'm even more confused now, the opening post mentioned the price of the dress as being €97.
You then say that each parent is owed '50 quid', that's a rip-off right there, €50 is hardly the equivalent of £50, the OP's parents would be very rich very quickly on that exchange rate, in fact they'd be fighting each other to take their beloved offspring on a - for them - lucrative shopping day-out, but wait, you then bring the word 'dollar' into the equation, plenty of countries use dollars as their currency, America and Australia for two, perhaps the OP is residing in Lexington or Lady Elliot Island, which would make your use of the word 'dollar' legitimate, however as the OP's stated location is Letterkenny (Saudi Arabia), then, if I'm not mistaken, the 'Riyal' would be the correct currency in which to conduct this imaginary transaction.

Do you work in a Bureau de Change?
If so, which one, I'd certainly like to avoid it if at all possible.
Good day to you!

Your parents both give you €50 each and you're moaning about a euro?
Buy your own dress ya sponger!! Lol

It's the new government puzzle levy. Letters should be going out next week explaining all about it.

A tax on idiots.

Your parents have paid 98.
You subtract the €1 you have.
That leaves 97(the price of the dress)
Any other way of doing this is wrong.

I've been posting there too, so I'm not surprised. There are some differences, though:
- if you're going to spend €97 on a dress, you can bet your mum wants a look at it first, and will make sure it's actually worth €97 before she'll lend you the money. (Your dad might be more of a pushover, of course.)
- Your parents don't usually charge compound interest. Imagine if that €97 became €99, then €105, then €118 ...
