Answer – Solution
The answer of the above puzzle is Rs.1000. Want to know How?
In order to calculate how much is the shopkeeper loss, we simply have to get the profit of the lady and other shopkeeper. Keep in mind that profit of someone is basically loss of the shopkeeper.
Loss of first shopkeeper = (Profit of the lady + Profit of the second shopkeeper)
Profit of the lady = Rs.200 (for goods) + Rs.800 (for the change she received) = Rs.1000
Profit of the second shopkeeper = Rs.0 (as he got his money back)
So the loss of the shopkeeper is = 1000 + 0 = Rs.1000
Another way to look at this problem is to check how much the first shopkeeper gave to others and what he took from others.
Loss of the shopkeeper = What he gave to others – what he gained from others.
What first shopkeeper gained -:
From Lady: Zero (as the note was a duplicate one)
From Second Shopkeeper: Rs.1000
What he gave or what he lost -:
To Lady :- Rs.200(goods) + Rs.800(change)
To second shopkeeper : Rs. 1000
So the net loss = (200 + 800 + 1000) – (1000) = Rs.1000
There are other ways to look at this problem but the answer is Rs 1000 !
