Answer: (4) Rs. 600

Explanation:-
The amount of money after two years = Rs. 720
The amount of money after seven years = Rs. 1020

The simple Interest of five years = 1020 – 720
= Rs. 300
Then, the simple interest for one year = 300/5
= Rs.60
Therefore, the simple interest for two years = 2 x 60
= Rs. 120

Then, Principal = 720 – 120
= Rs. 600
Hence, the answer is (4) Rs.600.
