Answer 1

Hello friend!!

Answer:

Rs. 100 becomes Rs. 300 in 15 years 6 months.

An interest of Rs. 200 is earned on Rs. 100 in 15 years, 16 months.

An interest of Rs. 100 is earned in 7 years and 9 months.

So, a sum of money doubles itself in 7 years 9 months.

I hope this helps you!

I also hope that you have a great day ahead!

If my answer satisfies you, then please mark it as the brainliest and give me a thanks!!
