Each guy pays $10 therefore 3 * 10 = $30
The cost of the pizza is $25
When the kid returned the $3 he made the assumption that $25 had been evenly
divided between the 3 guys when really - 2 had paid $8 and 1 had paid $9.
There's your extra dollar.

Three guys in a hotel call room service and order two large pizzas.
The delivery boy brings them up with a bill for exactly $30.00.
Each guy gives him a $10.00 bill, and he leaves.

That's fact!

When he hands the $30.00 to the cashier, he is told a mistake
was made. The bill was only $25.00, not $30.00.
The cashier gives the delivery boy five $1.00 bills and tells him to
take it back to the 3 guys who ordered the pizza.

That's fact!

On the way back to their room, the delivery boy has a thought...

these guys did not give him a tip. He figures that since
there is no way to split $5.00 evenly three ways anyhow,
he will keep two dollars for himself and give them back three dollars.
OK! So far so good!

He knocks on the door and one fellow answers.
He explains about a mix up in the bill, and hands he
guy the three dollars, then departs with his two-dollar tip in his pocket.

Now the fun begins!

Remember $30-$25=$5 Right? $5-$3=$2 Right?

So what's the problem?
All is well, right?
Not quite. Answer this:

Each of the three guys originally gave $10.00 each.
They each got back $1.00 in change.
That means they paid $9.00 each,
which times three is $27.00.
The delivery boy kept $2.00 for a tip.
$27.00 plus $2.00 equals $29.00.
Where the hell is the other dollar ??????????
