Question

In how much time the principal doubles itself at the rate of "7.5 %" according to compound interest

Answer 1

Explanation:

➡️ For example, if you invest $10,000 at 10 percent compound interest, then the “Rule of 72” states that in 7.2 years you will have $20,000. You divide 72 by 10 percent to get the time it takes for your money to double. The “Rule of 72” is a rule of thumb that gives approximate results.
