Answer: The Rate of return earned by Investment G is 8.37%, while the rate of return earned by investment H is 8.54%.
We have
Investment G Investment H
Future Value of returns 151000 271000
No. of years 7 14
Costs 86000 86000
Rate of Return Formula :
[tex]RoR = \left (\frac{Ending Value of investment}{Beginning Value of investment}\right )^\frac{1}{n} -1[/tex]
Substituting we get ,
Investment G
[tex]RoR = \left (\frac{151000}{86000}\right )^\frac{1}{7} -1[/tex]
[tex]RoR = 1.755813953^{0.142857143} -1[/tex]
[tex]RoR = 1.083740989 -1 = 0.083740989[/tex]
RoR = 8.37%
Investment H
[tex]RoR = \left (\frac{271000}{86000}\right )^\frac{1}{14} -1[/tex]
[tex]RoR = 3.151162791^{0.071428571} -1[/tex]
[tex]RoR = 1.085438096-1 = 0. 085438096[/tex]
RoR = 8.54%
