The simple interest on a sum of money will be ₹ 200 after 5 yr In the next 5 yr principal is tripled. What will be the total interest at the end of the 10th yr?
Correct Answer: ₹ 800
Explanation:
According to the question,
SI for 5 yr = ₹ 200
∴ Total SI for 10 yr = 200 + 600 = ₹ 800
When principal is trebled, then SI for 5 yr will also be treble and hence
SI for next 5 yr will be ₹ (200 x 3) i.e., ₹ 600.
