Other I have a math problem for you!

[Xentra]

One of my Nationstates friends asked this and it broke everyone's brain!


A kid borrows from his sister 50 bucks and from his cousin another 50 bucks, now he has 100 bucks. He buys a shirt with 97 bucks and receives as change 3 bucks.


He gives his sister back 1 buck and his cousin another 1 buck while 1 buck remains to him. So he now owes 49 bucks to each one of the borrowers.


Now the tricky part: 49 bucks + 49 bucks = 98 bucks + 1 buck in his pocket = 99 bucks


Where the heck is 1 buck?????

Also didn't he give one dollar back to his cousin meaning he only owed 48 bucks? Or is there another cousin?

This is a problem you shouldn't show to kids.

Man, this is great. I solved a problem a lot like this before where I figured out what the deal was with the missing dollar, but I don't remember how I did. It has something to do with the disparity between the $97 he paid and the $98 he now owes.

 

[GasMaskie]

The location of the last dollar is accounted for. The sister has 1, the cousin has 1, the kid has 1, and the store has the 97 dollars which the kid bought a horrendously overpriced shirt for. The part about the kid now owing $49 dollars to their sister and cousin is a clever way of providing irrelevant information to mislead us. What happened there is just adding up your debt, something non-material, with your current assets rather than accounting for the current location of every single dollar that exists in the question.

^I got the same answer as him. Ik it sounds like just piggybacking but I did before I scrolled down.

So he got the 100 Bucks lent to him.


so i'll simply put this as -100 since well ...its debt hence the negative.


so -100 debt with now +100 cash in pocket.


So with his +100 he buys an overpriced shirt


100-97= 3 so now we are at +3, -100


Debt is still -100 current cash is +3 and spend is 97


1 dollar is kept still at -100 debt


two dollars is given back debt is now at -98


-98 debt, +1 cash with 97 spent


1+97= 98 (spent +kept total)


98-98=0.

So I haven't carefully read every other reply so sorry if this sounds and appears uncannily similar to yours.


So first let's give the characters names.


The Kid = David


The Sister = Elise


The Cousin = Adam


David borrows $50 from Elise and $50 from Adam. From this, I can confidently say, the math at the bottom exists to throw the reader a curveball.


If 1 person lent David $100, then $1 would be 1% of his debt. However, in the case of each person lending him $50, $1 is 2% of his debt.


It rounds out to the two total debts being 49.5% of the total 100% each, meaning they are 99% of the total debt, leaving the 1% David pocketed to be entirely real.

At least we have learned that 97 dollars is way to much to pay for a shirt.. seriously Wallmart has t-shirts for 10 bucks each..
