Question 2

Answer 1

1. The annual rate of return of the investment that doubled in 15 years is 4.7%.
2. The annual rate of return of the investment that doubled in 8 years is 9 years.
3. The annual rate of return of the investment that doubled in 20 years is 3.52%.
4. The number of years it would take the investment to double is 9.97 years.

What are the annual rate of return?

The formula that can be used to determine the annual rate of return is:

g = (Future value / present value)^(1 / number of years) - 1

2^(1/15) - 1 = 4.7%

(1600 / 800) ^(1/8) - 1 = 9%

(200,00 / 100,000)^(1/20) - 1 = 3.52%

Number of years =  (In FV / PV) / r

Where:

• FV = future value
• PV = present value
• r = interest rate

IN2 / 0.0695 = 9.97 years
