Once,three men went to a restaurant.Their bill was $25 and each of them paid $10 each. The waiter took the money to the cashier and brought back $5. Since the money couldn't be shared equally among them,he gave $1 to each man and took $2 as a tip. Now, each man paid 9 dollars, which takes 27 plus two (from waiter) = $29. $30-$29=$1.
Where did the dollar go?
