Questions People May Ask:

  • If a sum of money doubles in 8 years when compounded annually, what is the rate of interest?

Solution: Let’s denote the principal as P and the rate of interest as r%. According to the question, we have 2P = P(1 + r/100)^8. Simplifying this equation gives (1 + r/100)^8 = 2. Taking the eighth root on both sides and subtracting 1 gives r/100 = (2^(1/8)) - 1. Therefore, r = [(2^(1/8)) - 1] * 100, which is approximately 9.06%.

  • A sum of money becomes five times of itself in 10 years when compounded annually. What is the rate of interest?

Solution: Let’s denote the principal as P and the rate of interest as r%. According to the question, we have 5P = P(1 + r/100)^10. Simplifying this equation gives (1 + r/100)^10 = 5. Taking the tenth root on both sides and subtracting 1 gives r/100 = (5^(1/10)) - 1. Therefore, r = [(5^(1/10)) - 1] * 100, which is approximately 17.46%.

  • If a sum of money triples in n years when compounded annually, what is the rate of interest?

Solution: Let’s denote the principal as P and the rate of interest as r%. According to the question, we have 3P = P(1 + r/100)^n. Simplifying this equation gives (1 + r/100)^n = 3. Taking the nth root on both sides and subtracting 1 gives r/100 = (3^(1/n)) - 1. Therefore, r = [(3^(1/n)) - 1] * 100.
