is Rs 1000.
Congratulations Scribblehappy, DI and Jayadev for getting it right! *Clap clap* 🙂
A big thanks to all those who attempted to answer my brain-teasing question here. You all have been a sport!
Now the explanation for the answer :
The 2nd shopkeeper gave Rs. 1000 to the 1st shopkeeper and took it back since he was given a fake note. So that transaction is null and void.
The 1st shopkeeper ended up giving goods worth Rs. 800 to the lady and also gave Rs. 200 as change.
So the loss incurred would be Rs 1000.
Ok, now your turn to ask a riddle.. 😀
