Hi Priyanka, hope this helps. This is a more logical approach to this question. In compound interest (CI), the amount doesn't grow at a constant rate, but the growth rate itself increases over time.10 years: The money doubles (becomes 2 times the original).Another 10 years: The doubled amount doubles again (becomes 4 times the original).Therefore, it takes a total of 20 years for the money to become 4 times the original amount.
