P principal will turn to 2P in 70/r years.

In this specific case, 5000 will turn to 10000 in 70/8 (8.75 years)

We are asked to calculate the amount in 18 years.

[spoiler]In the first 8.75 years, 5000 will turn to 10,000.
In the second 8.75 years, 10000 will turn to 20,000. Hence answer A[/spoiler]

Great explanation, Thanx. Without anything I was making it complicated. Now I'm feeling like It was an easy question.
