I got this msg from my uncle which claims that 99 out of 100 university students will get it wrong. haha. we shall see. This is the question.

There is this customer who went to a shop to buy a gift.
The gift cost $18 but the shop is selling at $21.
The customer decided to buy the gift and gave the shop owner $100.
The shop owner dun have short change for the customer, so he went outside the street to look for people (Mr A) to change $100 into smaller notes and returned $79 to the customer.
Mr A suddenly went back to the shop and told the shop owner that the $100 is a fake note.
So the shop owner bo bian had to return back Mr A $100.

So the question here is: How much the shop owner lose in total?

Reply reply!! Ans will be posted (even if nobody ans me) after few days.
=( hahaha.
