You borrow $50 from your mom and $50 from your dad to buy a T-shirt.

The T-shirt costs $97 and you receive $3 change.

You give $1 to your mom, $1 to your dad and keep $1 to yourself.

Now you owe $49 to your mother $49 to your father and the $1 you kept to yourself.

$49+$49+$1 = $99.

 

Where did the last dollar go?

You're welcome.

You could've googled it though, it's a pretty well known math mistake to trick people. 

If you like, have a look at my comment in this one; (2=1) http://web2.0calc.com/questions/i-need-help-with-this-ecvation  

It's another faulty riddle...

You're making the wrong addition here,

The money you need to put together to pay your parents back is

49+49-1 = 97, because you already have 1 dollar.

 

Because you keep 1 dollar to yourself and only give 2 dollars to your parents

the money you still need to pay back to your parents is $98 (of which you already have 1 dollar)

 

The t-shirt shop has 97 dollars, your mum has 1 dollar, your father has 1 dollar and you have 1 dollar which totals 100 dollars.

 

To summarize, there is no missing dollar.

This is an old one but a good one. Thanks Rhino.

I have given it the puzzle icon and copied the question into 'Puzzles' which is a Sticky note thread.

I have directed people here for the answer.

Neat huh?

This is where I put it.
