Figure this out:
Three men in a hotel call room service and order two large pizzas. the delivery boy brings them up with a bill for exactly $30. Each man gives him a $10, and he leaves.
When the delivery boy hands the $30 to the cashier, he is told that a mistake has been made. The bill was not $30, but in fact $25. The cashier give the delivery boy five $1 bills and instructs him to give it back to the men who ordered the pizza.
On his way back to their room, the delivery boy has a thought ... these men didn't tip him. His figures that since there is no way to split $5 evenly three ways he will keep $2 as a tip and give them back $3.
He knocks on the door and one of the men answers. The boy explains about the mix-up with the bill, and hands the men $3, then departs with his $2 tip in his pocket.
Now the fun begins:
$30 - $25 = $5. Correct? $5-$3 = $2. Correct?
So, what's the problem?
All is well, right?
No. Not quite. Answer this
Each man originally gave $10 each.
They each got $1 in change.
That means they paid $9 each, and multiplied by three is $27.
The delivery boy kept $2 for a tip.
$27 + $2 = $29
Where is the other dollar?

I got it:
the last line is misleading...you must look at what was paid in: 9*3=27, and what was kept, 25 ffor the pizza and 2 tip...this adds up to the 27
