Ok solve this.

You see a shirt for £97, but you haven't got the money to buy it, so you borrow £50 off your Mum and £50 off your Dad. £50+£50=£100. You buy the shirt and have £3 change, you give your Mum £1, your Dad £1 and keep £1 to yourself.

Now you owe them both £49

£49 + £49 = £98 + Your £1 = £99

Where's the other Pound?

[Jake.]

On the bus money I needed to get to the shop

This is annoying...

erm

[Jesus.]

The pound is missing because you've taken it out of the equation. Split that pound between your parents, and £48.50 x 2 = £97. The problem arises when people who want free shirts, take part of the change.

in your pocket!

What Jesus said

[Kazanne]

If you borrowed £50 each from mum and dad and returned £1 to both of them, that means that all you borrowed from them is £49 each.
Okay 49+49= 98
You bought a shirt for 97 and kept 1 which still equals 98. So you see there's no missing pound because what you worked with is 98 because £2 was returned from the original 100pound.

Yeah, you've short changed your parents. Basically they have paid 48.50 each for your shirt at 97. So if you give them 1 back each and keep one for you, that one for you should be split by two (50 pence each) for your parents.

48.50+48.50=97

the pound back each:

97+1+1=99

Then add the pound you kept:

99+1=100

What? That makes no sense, Salman.

The 49 comes into play after you give them 1 each, not before.
