IQ test, can you find the mistake?

lol

You have it. You only used $97, then you gave each parent a dollar back =$99 + the $1 you still have.

If a+b equals 76 and a - b equals 38.......... So subtract 38 from 76. That equals 38. 38 divided by 38 is.................. 1.

Yall must be engineers.

this was first guess......

[nursejenn]

lol

Your $1 is technically already included in the $98 since it was originally borrowed... So the equation should say,
$49 to mom + $49 to dad= $98+ $2 total returned to parents = $100

Or...



Maybe Obama took it...

Checking in. I read this right after you posted it. Still searching.......

now that makes sense. My brain went all Forest Gump on me.

Here's a better one, I should have known TBH members are too smart! Don't scroll past this post if you want to figure it out on your own.

76/38=2, therefore
A+B = 2(A-B)
A+B = 2A-2B
A-A+B = 2A-A-2B
B = A - 2B
B+2B = A - 2B + 2B
3B = A
3B/B = A/B
3 = A/B

You can check the math to figure out what A and B are if you like by sticking A=3B into either equation figuring out B =19 and then putting that in for B in either equation to figure A = 57 and then checking 57 / 19 = 3.

Lol. Was about to say, he pulled some Uncle Sam math by doing the equation wrong, but you beat me to it.

A better question is why would you pay 97 bucks for a shirt?

[Dry Ace]

That shirt thing is a pain...adding backwards lol
