... goods worth rs.200 from a shop. (shopkeeper selling the goods with zero profit).
The lady givs him 1000 rs note. The shopkeepr gets the change from the next shop and keeps 200 for himself and returns rs.800 to d lady.
Later the shopkeepr of the next shop comes with the 1000rs note saying "duplicate" and takes his money back.
How much LOSS did the shopkeepr face?????
