The rate at which the investment gets double is 7.776
Step-by-step explanation:
Given as :
The principal investment = $ 5051
The time period of investment = 9 years
Let The rate of interest = R % compounded quarterly
The Amount gets double
So, From Compounded method
Amount = Principal ×![(1+\dfrac{rate}{4\times 100})^{4\times Time}](/tpl/images/0391/3850/4f073.png)
Or, 2 × P = P × ( 1 +![\dfrac{\textrm R}{400})^{\textrm 36}](/tpl/images/0391/3850/6ee53.png)
Or, 2 = ( 1 +![\dfrac{\textrm R}{400})^{\textrm 36}](/tpl/images/0391/3850/6ee53.png)
Or,
= 1 + ![\dfrac{\textrm R}{400}](/tpl/images/0391/3850/3a1da.png)
or, 1.01944 - 1 =![\dfrac{\textrm R}{400}](/tpl/images/0391/3850/3a1da.png)
or, 0.01944 =![\dfrac{\textrm R}{400}](/tpl/images/0391/3850/3a1da.png)
∴ R = 0.01944 × 400 = 7.776
Hence The rate at which the investment gets double is 7.776 Answer
