Ok I heard this from some one else and I really don't get how it works. Here it goes:

3 studens go an buy a second hand car.
The car is $30. So they all pay $10.
After they leave, the former car owner decides to give them back $5. So he sends his helper to find them and give them the $5 back.
The helper decides to keep $2 and gives $3 back to the students.
Now all of the students have paid 9dollars. it you take the student money $9 X 3 = $27 + de $2 from the helper = $29! where did the $1 dollar go? I now you can't buy a car for 30 dollars, but it would be the same if you made it in to 30.000 dollars. That is not the point. I just want to know where the $1 went.
