"You saw a shirt for $97. You didn’t have the cash, so you borrowed $50 from your mum and $50 from your dad = $100. You bought the shirt, and had $3 change. You gave your dad $1 and your mum $1 and kept the other $1 for yourself. Now you owe your mum $49 and your dad $49. 49+49 = 98 + your $1 = 99. Where is the missing $1?"
Well, this really isn't all that hard to understand, so I'll just illustrate it for you.
As you can see, the error is in the question.
You OWE them $98, and you HAVE $1 left. Adding those two figures together wouldn't make much sense.
You owe your parents $98 becuse you already returned $2. You owe your mother $49 and your dad $49, because you gave them $1 each.
You have $1 because $97 went towards the shirt, and $2 was returned to your parents.
EVERYTHING ADDS UP, IT'S JUST THE STUPID FUCKING QUESTION THAT DOESN'T MAKE SENSE.
