Mr. Rahul Kaushik You are absolutely wrong.
And Mr Sandeep Wahwal You too are Wrong. . .
I have explained the Correct answer in One of My Comments above. Please Refer it.
Mistake in Your Answer is that : You have Shown Receipts of Rs.1000/-+200/-(Kept with him)
From where do u think He got this 200/- ???? This 200 is Out of Rs.1000/- recd. So U r Counting it Twice.
