a shop sell a pair of jeans at $50, you ask you mother for $25 and your father for another $50. you go to the shop and they give you $5 discount, you go back home and give your mother $1 back and your father a $1, so you owe your parents $24 each and you have $3 extra. now $24 + $24+$3= $51 how do you get the $1 extra?
trust me there is a solution?

You're adding the wrong numbers. The $3 in your pocket is part of the $48 you owe your parents, not something in addition to it. The proper accounting is $45 for jeans + $2 to parents + $3 extra = $50.

You must be doing it wrong or typed it wrong because...
25 mother + 50 father = $75
75 - $50 jeans + $5 discount = $30
$30 - 1 (mom) - 1 (dad) = $28
$28 + 3 extra = $31
Mother: 25 - 1 = $24
Father: 50 - 1 = $49
Combined you owe them: $73
If you meant 25 from each parent (not 50 from the dad):
25 mother + 25 father = $50.
75 - $50 jeans + $5 discount = $5
$5 - 1 (mom) - 1 (dad) = $3
$3 + 3 extra = $6
Mother: 25 - 1 = $24
Father: 50 - 1 = $24
Combined you owe them: $48
and this I raise of few eyebrows of my own: 1st. If you gave both parents a dollar each, then you should be missing $2 dollars only, meaning that you'll have $24 each and 5 extra, or $25 each and 3 extra depending on how you split it, not 24 each and 3 extra, which means you must've given them both $2.
2nd, assuming that you did have the right amount of $51, it is because you originally had something for sale as an even-numbered item and you'd owe each parent ($50: 25 each in what I thought you meant, or $75: 50/25 in your example), so it's even and easier to split. However, being an odd number (1-3-5-7-9, etc), it means whatever change you get back is also odd (try the equation if it was for $50 with a bit of money from your aunt... Who gets the 2 pennies after $16.66?), so it does result in an extra dollar. If it was me, I'd pocket it and not tell them about the discount, but good ol' honest you should divide it up and give both parents $0.50.
3rd, why do you want to give them ALL your pocket change, assuming that you had $3 that was yours? I'd never go anywhere with an empty wallet no matter how much I owe!

You stated the question incorrectly: you meant to say $25 from the father as well as from the mother: then the problem "makes sense".
But the problem comes down to signs: your mother and father each have (-25) when you have borrowed from them. When you get the $5 discount and give them back a dollar each, their account with you is now (-24) each. You have +3. When you add these, you should see it is (-24) + (-24) + 3 = (-40), which is what you spent on the jeans and now owe them. If you take 24 twice and add 3 you have ignored the fact that they have opposite signs.

the calculation $24+$24+$3 is wrong. discount is $5. $3 is with me & the remaining $2 i gave to mom &dad $1each.so no mistake in calculation.no extra $1.

The $3 in your pocket is from the discount you received from the shop ($5 minus $2 to your parents).

1.
u = $0
ma = $25
pa = $25
shop = $0
2.
u = $50
ma = $0
pa = $0
shop = $0
3.
u = $5 (cos of discount) + jeans
ma = $0
pa = $0
shop = $45
4.
u = $3 + jeans
ma = $1
pa = $1
shop = $45
So it should be you owe your parents $24 each, altogether you owe $48.
Minus the $3 you have, $48-$3=$45=$45.

I trust you there is a solution...
Borrowing money and spending it is different...
Borrowed: $24 (mother) + $24 (father) = $48
Spent: $45 (jeans) + $3 (you holding on to) = $48
So, you see.. there is no excess or shortage at all...
Cheers... (",)

TIS A FALLACY!!!
nah it doesn;t even work
25 (mum) + 50 (dad) = 75
jeans cost 50-5=45
75-45=30
30-1(mum)-1(dad)=28
and I can;t be bothered to do the rest (lousy answer, I knwo)
but i have to go somewhere
