Ok, I am a believer that math is not perfect as all math professors claimed to be. So here is my story.
3 men rent a room at a hotel, at the front desk they tell them that it will cost them $30 for the night for the room with 3 beds, so each of them pay $10.
10 minutes later, the front desk calls the bell boy and ask him to return $5 to the 3 gentlemen that just checked in and are now in room 1015. On his way to the room the bell boy decided that he can’t split the 5 ones into the 3 men, so he puts $2 in his pocket, and knock on the door and tell them that they were over charge for the room and hands each of the men $1 so now each men paid after their refund, $9 and here is where all happens, $9 X 3 = $27 + the $2 he packed in = $29, where is the other $1 ?

Good one, and once again we are proved wrong. Cute, I will use it in class. If I was one of the gentlemen, I would have requested credit back to my visa and the lost or surplus $1 can be use as an IOU for those that don't accept reality.

If I had a nickel for every time this problem was posted here...
Math is most certainly not perfect when you're doing it wrong! There is no extra dollar. Of the $30 originally paid by the men, $25 went to the hotel, $2 went to the bell boy, and $3 went back to the men. Every dollar is accounted for.
The problem is stated in such a way as to be deceptive. You don't add the $2 to the $27, you subtract it, in order to determine how much the hotel received.

This is the best example to perform an illusion. The bill was 30, but after returning the money and the boy putting 2 in his pocket the bill changed to 29.
Nothing is lost: 25 in hotel box, 2 in boy´s pocket and 1 in each man´s pocket.

they did not pay $9. Look at it this way, they paid $25 total b/c the $5 was to be returned. $25 plus $3 that they got back is $28, plus the $2 that the bell boy took equals $30. Problem solved.

Math is perfect, your analysis is flawed.
Each man pays $9. 3*$9=$27 payed total.
The hotel collected $30-$5=$25.
The bell boy collected $2.
Payed: $27
Collected: $25+2=$27

ummm yea, 9+9+9+2=$29 but 25/3= $8.33 Did each paid $8.33 or $9 and if each end up with a$1 in their hands wouldn't that means $10-1=9 ? ummm ...

Math is not perfect...The world was not founded based on Mathematics...this series of equations, signs and numbers or whatever you want to call it, was devised as a means to help better understand the world around us.
