In a shop, a woman bought goods that worths N200, she gave the shopkeeper N1000 note..

The shopkeeper had no change, so had no other choice than to go look for change... He at last got a man who gave him change of N1000 in N200 denomination...

He got back to the woman and gave her N800 as her balance..

Later, the man who had given the shopkeeper the change, returned with the claim that the N1000 note was fake.. So the shopkeeper gave the man another N1000 and destroyed the fake N1000..

So how much has the shopkeeper lost?
