Answer:
a.
(i) Rate of return=(2+(38-40))/20=0%
(ii) Rate of return=(2+(40-40))/20=10%
(iii)Rate of return=(2+(42-40))/20=20%
b.
(i) Real rate of return=(1+0%/1+3%)-1=0%
(ii) Real rate of return=(1+10%/1+3%)-1=6.8%
(iii) Real rate of return=(1+20%/1+3%)-1=16.50%
Step-by-step explanation:
a. The return on any stock can be calculated using the below formula
Return=(Dividend+Capital gain)/Opening value of stock
Where Capital gain=Closing value of stock- opening value of stock.
Using the formula above
(i) Rate of return=(2+(38-40))/20=0%
(ii) Rate of return=(2+(40-40))/20=10%
(iii)Rate of return=(2+(42-40))/20=20%
b. The Real rate of return can be calculated using the below formula:
Real rate of return=(1+ rate of return/1+inflation rate)-1
(i) Real rate of return=(1+0%/1+3%)-1=0%
(ii) Real rate of return=(1+10%/1+3%)-1=6.8%
(iii) Real rate of return=(1+20%/1+3%)-1=16.50%
