Three friends went to eat at a restaurant,and were billed 30dollars, thats 10 dollars each. The waiter collected the money but was told by the cashier that their bill was 25 dollars, so he should return 5 dollars. He, however kept 2 dollars for himself and returned 3 dollars to the guests. Now check this: since 3 dollars was returmed to them, it means the friends paid 9 dollars each for their meal. 9x3= 27 plus the 2 dollars kept by the waiter =29 dollars. What happened to the 1 dollar? Lets crack our brains.

$9x3=$27+$3=$30
Not 27+2 cos the $2 the waiter kept is part of the $27 the friends paid so $1 didn't go anywhere...

It's jst a wrong calculation!!!

25+2+3=30

from their pockets came 9x3=27+ the 3dollars that went to the cashier =30dollars abi, what about the 2dollars that the waiter took?
