Question
An amount on compound interest is doubled to the original amount in 3 years. In how many yearswill it be eight times its original amount
Solution
The problem is based on the concept of compound interest.
Given that the amount doubles in 3 years, this means that the interest rate is such that it causes the amount to double in 3 years.
We need to find out how long it will take for the amount to become eight times its original amount.
Since 8 is 2^3, and the amount doubles every 3 years, it will take 3*3 = 9 years for the amount to become eight times its original amount.
So, the answer is 9 years.
