The problem is about compound interest. We know that the sum of money doubles itself in 15 years. We need to find out when it will become eight times of itself.

Let's break it down:

1. If the money doubles in 15 years, it means it multiplies by 2^1 in 15 years.
2. We need to find out when it will become eight times of itself, which means it multiplies by 2^3 (since 2^3 = 8).
3. Therefore, it will take 3 times the original period of 15 years to become eight times of itself.
4. So, the money will become eight times of itself in 15 years * 3 = 45 years.

So, the answer is 45 years.
