11. 1) A lady buys goods worth Rs. 200 from a shop
(shopkeeper selling goods with zero profit) lady
pays with a 1000 Rs note to the shopkeeper. He
gets change from the next shop & keeps 200
for himself & returns 800 to the lady. After
sometime the next shop owner returns the
1000 Rs. note saying it is fake & takes the
money back. How much loss did the
shopkeeper suffer?
12. Answer: Rs 1000
Profit or Loss= Money Received-Money Given
In this case,
Fake note is Equivalent to Rs. 0
So,
Actual Money Received= Rs.
0 (Lady)
+Rs. 1000 (Neighbour)
---------------------------------Total= Rs. 1000
---------------------------------Money Given=Rs. 200 (Goods)
Rs. 800 (Change to Lady)
Rs.1000(Neighbour)
---------------------------------------Total=Rs. 2000
---------------------------------------Profit/Loss= Money Received-Money Given
=Rs.1000-Rs.2000
=Rs. -1000
Thus a Loss of Rs. 1000
