Whoever can help me with this question, gets cookies.

You see a shirt for £97 but you have no money. So, you borrow £50 from your mum and £50 from your dad=£100. You buy the shirt and get £3 change. You keep £1 for yourself, and give £1 to your mum and £1 to your dad. You now owe your mum £49 and your dad £49 = £98, plus the pound you kept for yourself=£99.

Where is the missing pound?

WTF?!

[Gazoid]

Eh that makes no sense, why would you owe yourself a pound? You'd be a pound up.
If you had a brain, you'd split that £1 into 2x 50p and then give one 50p to each parent, you then only owe the cost of the shirt

DERP

:/ it's not a REAL question (or there would be tax in the mix) it is a math troll question. The wording confuses the weak minded into being unable to account for a missing dol...er...pound. This is acutaly early basis of the "Change Con" used by some people to scam cash from store register workers (someone tried it on me once and failed when I simply corrected the math every turn).

The question uses wording to trick you into breaking the equality on your equasion. Maintaining equality demands that anything you do to one side, must be done to the other.
6X=y (6X)/6=(Y)/6 X=Y/6

NOTE that (perentises) will be used here as Notation... the opposite of their normal mathmatical application.
So when I say 6X(/6), That is NOTATION for what would MATHMATICLY be written as: (6X)/6
The only wording used on this bit to confuse is "plus the pound you kept for yourself=99".
You start by oweing $100 ($50 mom + $50 dad)
100=SHIRT+3 (Shirt=97) *you buy the shirt and get $3 change
100(-2)=SHIRT+3(-2) that is the "show your work" version of giveing your parents $1 each twords your debt.
98=SHIRT+1
This is where the question tries to confuse you. The PROPER math would be to SUBSTRACT the doller from both sides or to leave both sides as is. Instead, the working ADDS it to one side and fails to do so on the other. This is where the equasion looses eqality, and this is where your "missing pound" is created.
*proper 98(-1)=SHIRT+1(-1) 97=SHIRT (the price of the shirt is $97) to subtract from both sides would be to pay that dollar you kept to one or both of your parents.
Otherwise, 98=SHIRT+1 is the final solution. You owe your parents $98 and you have the shirt and the $1.

Instead, you add a dollar to the 98 to get 99... that demands you add a dollar to the other side, and where the hell are you getting that dollar you are adding!? Does that properly explain WHERE the question is forceing the confusion?

mindfucked.

[Pestilencemage]

they use the wording to move money to the other side of the equasion without you noticeing (hopefully).
That is how the con works.

"plus the pound you kept for yourself" moves a dollar. that is the lost dollar.

Whoever buys a shirt of 97 pounds is out of his mind anyway.
For that price i buy like 6 shirts.
