Solution

Total loss is of Rs. 100

Description: Rs. 60 Watch + Rs. 40 Payback to girl = Rs. 100 loss

The loss faced by shop keeper due to the watch is Rs. 60. Then he took change for 100 rupees from fruit seller out of which he returned Rs.40 to the girl. And he had Rs. 60 remaining of that change. When the fruit seller approached for money he put Rs.40 from his pocket along with the 60 he already had he paid 100 to the fruit seller.
