A Riddle JonBro can't cope with. 2011-08-04 16:02:13 Reply

My brother asked me this after a friend messaged him it on Facebook. I found this worded one off a forum, because I couldn't understand him.

"You saw a shirt for £97. You didn't have the cash, so you borrowed £50 from your mom and £50 from your dad = £100. You bought the shirt and had £3 change. You gave your dad £1 and your mom £1 and kept the other £1 for yourself."

Now you owe your mom £49 and your dad £49. 49+49 = 98 + your £1 = 99. Where is the missing £1?

Bronies are welcome.

I can't figure out how to solve it the way you worded it, but ultimately there's $1 in your hand, $1 in your mom's hand, $1 in the dad's hand, and $97 in the store. That makes 100.
I have two questions.
What does JonBro have to do with this?
What the fuck kind of amazing shirt costs $97?

But like the rest of the people on this forum, I'm going to say i shoved it up my ass.

Yea, there is no 1 Dollar bill left, but the question is, where did the calculation go wrong in op's riddle?

There is no missing dollar, you don't add the $ you kept for yourself. Also pound signs, fuck off.

Start: 50+50 = 100. (Borrowed, you have this money, it is credit in your pocket)
Buy shirt, 100 - 97 = 3 (You spent 97, you have 3 in your pocket.

The 49+49 part is where the calculation is incorrect. There is no 49+49, there is 50+50 with 3 remaining due to losing 97. The 49+49 of DEBT + 1 of CREDIT does not = 98, it = 97.

You _OWE_ your parents 49 each, which means the number is actually -49 + -49 which = -98. The debt is 49 to each parent because you already gave them each 1 in change, right? And you have 1 left over which you kept. So knowing our current number is -98 (as in, 98 in debt, not 98 in credit) and adding that 1 that you kept for yourself (which is credit) it becomes -97.

-98
+
+1 (this is your missing 1 pound - the one you kept)

Which leaves you with -97, which was how much you spent on the shirt.

Oh, you solved it! Congrats!

For a while there it seemed completely illogical and unpossibly resolvable...

Like Simon said, there isn't a missing pound. 49+49 = 98 and the 'missing' pounds have already been given back, £1 to the mum, £1 to the dad. = £100. The pound kept is irrelevant.
