The answer is clearly Rs. 1000. The other shopkeeper has no bearing on the answer, he's been mentioned only to confuse the reader. Think of it as an equation : Profit of the lady = Loss of the shopkeeper. Since the lady made a profit of Rs. 1000, i.e 200 in goods and 800 in cash, therefore, the loss of the shopkeeper must also be Rs. 1000.
