Let’s revisit the problem …
You saw a shirt for $97.
Having no cash, you borrowed $50 from your mum and $50 from your dad.
$50 + $50 = $100.
You bought the shirt, and had $3 change.
You gave your dad $1 and your mum $1. You have a dollar in your pocket.
You now owe your mum $49 and your dad $49.
$49 + $49 = $98. Add the $1 you still have = $99.
Where is the missing dollar?
The first point to be made is that if you have no money, what you need from your shirt is that it make a good impression at your next job interview … $25 at target.
Secondly, if you have $3 in your pocket, no matter how it came to be there, and you give $1 to your Mum and $1 to your Dad you will have $1 left … the world does not owe you an extra dollar.
So let’s take it from the beginning …
You borrow $50 each from Mum and Dad. You have $100 in your hand.
You spend a ridiculous amount on a shirt and now you have a shirt in one hand and $3 in the other.
You give two dollars away, you are left with $1, a shirt and, because you reduced your $100 debt by $2, a debt of $98 … what else did you expect?
The puzzle evaporates in the face of logic but on first reading it has a certain pull … because it invites you to do a sum that simply isn’t itself logical and leads to a wrong answer.
If you saw straight through the puzzle congratulations.
If you didn’t you may need to temper your expectations at the job interview.
If you wrote the puzzle there’s a guy in Canberra named Wayne Swan who needs a hand finding a few missing dollars.
