Old Classical :The missing dollar (Difficulty Level : Medium)

Three men in a cafe order a meal the total cost of which is $15. They each contribute $5. The waiter takes the money to the chef who recognizes the three as friends and asks the waiter to return $5 to the men.
The waiter is not only poor at mathematics
but dishonest and instead of going to the trouble of splitting the $5 between the three he simply gives them $1 each and pockets the remaining $2 for himself.
Now, each of the men effectively paid $4, the total paid is therefore $12. Add the $2 in the waiters pocket and this comes to $14.....where has the other $1 gone from the original $15?

  1. Assume that the bill comes of $10 n d three frns paid $3.33 each. Waiter Gives $1 to each. So Each Frnd got $4.33. $4.33*3=12.99=13 n wen we add $2 of waiter's we get $13+$2=$15

  2. "each of the men effectively paid $4, the total paid is therefore $12" - Here $12 is for => meal $10 + Tip to waiter $2.

    Other $3 they have got back $1 each.
