A lady buys goods worth Rs 200 from a shop, whose shopkeeper is selling the goods with zero profit.

• The lady gives him a Rs 1000 note.      
•  The shopkeeper gets the change from the next shop, keeps Rs 200 for himself, and returns Rs 800 to the lady.
•  Later the shopkeeper of the next shop comes with the Rs 1000 note saying “fake note” and takes his money back.

Shopkeeper to Lady  =    Rs. 200 goods + Rs. 800 change  = Rs.1000    (EARN  –Rs.1000 ) – LOSS

Shopkeeper 2 given and took back Rs1000   –   NO NEED TO CONSIDER
