Then SHOPKEEPER A says ohk I'll give you 8 pens it will cost ₹10 for each pen. ( where 1 pen costs ₹5 to shopkeeper and he sells it for ₹10 to customers) Customer says ohk I'll buy 8 pens for ₹80 and gives a note of ₹100 to SHOPKEEPER A. Now SHOPKEEPER A has to return ₹20 to the customer but he doesn't had change. So he goes to SHOPKEEPER B gives him note of ₹100 which he took from customer and in exchange gets 10 notes of ₹10 from SHOPKEEPER B. Comes back with change of ₹100 and gives ₹20 and 8 pens to the customer. After some time SHOPKEEPER B comes and says that the note of ₹100 you gave me is fake and tears it in front of SHOPKEEPER A and asks SHOPKEEPER A to give his ₹100 back.
