This is a simple but really confusing puzzle. Lets decode it in the simple and understandable way.

Net Loss = (goods/money gone out of his hands in the transaction) - (goods/money he got in the transaction)

goods/money gone out of his hands in the transaction
a) goods worth Rs 200
b) Rs 800 which he paid to lady as balance
c) Rs 1000 (original Note) he gave to shopkeeper2 in exchange of fake note

goods/money he got in the transaction
a) The leftover Rs 200 change (First he got change for Rs 1000 from shopkeeper2 and gave Rs 800 to the lady and he is having remaining 200 with him)
b) Fake note of Rs 1000 ( No value)

Net Loss = (200 + 800 + 1000) - (200)
Net Loss = Rs: 1800

The shopkeeper is in a loss of Rs 1800 in this transaction.

net loss is actually 1000rs. The change of 1000 from next shop is also included into total money he got in transaction.

There are three transactions here.Customer <==> shopkeeper - customer gives bad Rs 1000 note to shopkeeper - shopkeeper gives goods worth Rs 200 to customer - shopkeeper gives change worth Rs 800 to customershopkeeper <==> shopkeeper2 - shopkeeper gives bad Rs 1000 note to shopkeeper2 - shopkeeper2 gives Rs 200 and Rs 800 to shopkeepershopkeeper <==> shopkeeper2 - shopkeeper2 gives bad Rs 1000 note back to shopkeeper - shopkeeper2 takes Rs 1000 from shopkeeperSo, lets review each actor:Shopkeeper2: - Lost Rs 200+800, gained bad Rs 1000 note - Lost bad Rs 1000 note, gained Rs 1000 Net: evenCustomer: - Gained goods worth Rs 200 - Gained Rs 800 - Lost bad Rs 1000 note Net: + Rs 1000 - bad noteShopkeeper - Lost goods worth Rs 200 - Lost Rs 800 - Gained bad Rs 1000 note - Lost bad Rs 1000 note - Gained Rs 200 - Gained Rs 800 - Lost Rs 1000 - Gained bad Rs 1000 note The last 6 bullets cancel eachother out Net: - Rs 1000 + bad note

the neighbour shopkeeper is only to confuse you. neighbour gave 1000 rs good notes and got it back. But the first shop keeper gave goods 200 and good notes 800.. so total loss is 1000.

Goods to lady = 200 Cash given to lady = 800 = 1000Less money kept for himself = 200= 800Return to next shop = 1000Net loose = 1800

Here is another way to find the solution: use the property that the total value is constant.At the beginning, the shopkeeper has 200, the next shopkeeper has 1000 and the lady has nothing. Total: 1200. At the end, the next shopkeeper still has 1000, the lady has 800 (cash) plus 200 (goods). These two have therefore 2000. The shopkeeper must have -800 to keep the balance at 1200. At beginning, he add 200, so he lost 1000.

The answer seems to be wrong. You counted twice the 800 paid to the lady: in the first b) and in the brackets of the second a). The loss is actually 1000.
