Hi! Here is the answer to your query. Let the principal amount and the rate of interest be P and R% per annum respectively. Given : Time (T) = 8 years and Sum of money doubles itself ⇒ 2P = P + Simple Interest ∴ The rate of interest for which the sum of money doubles itself in 8 years is 12.5% per annum. Cheers!

Principal = P R = R T = 8 According to Question 2P = P * R * 8 / 100 2 = 8R / 100 R = (2* 100) /8 R = 200 / 8 R = 25 Ans: 25% Posted by Abhinav Verma(student)
