3 friends went to a small pub and had some food. When the bill came, it said $75. They paid the waiter $25 each but the owner thought that they should be given a discount and hence gave $5 to the waiter to return it to them. The waiter was a corrupt one, he took $2 from there and evenly returned the $3 among the three friend i.e, each $1. So that makes it, each friend pays $24. But now, If we add $24+$24+$24 ( three friends' money) + $2 ( taken by the waiter) that makes it $72+ $2 = $74. Where did that $1 go? Please answer!
PS ( for the moderators) : Its not a joke
PPS: the waiter wasn't one of the friends
