This is the question
My answer is: 1000A lady buys goods worth $200 from a shop. (shopkeeper selling the goods with zero profit). The lady gives him $1000 note. The shopkeeper gets the change from the next shop and keeps 200 for himself and returns 800 to the lady. Later the shopkeeper of the next shop comes with the $1000 note saying that its Fake note and takes his money back. How much LOSS did the shopkeeper face?
Someone confirm/correct me.
