Answer:
a. 12.03%
b. 3.32%
Step-by-step explanation:
The computation is shown below:
As we know that
Expected rate of return = Risk free rate of return + [Beta × Risk premium]
Let us assume Risk free rate of return be x and Risk premium be y
Now the equations are as follows
For Pete Corp
19 = x + 1.80y ...................... (1)
For Repete Corp
16.3 = x + 1.49y .....................(2)
Now Solving (1) and (2)
After solving we get
y = 8.70967741935
x = 3.3225806452
i.e Risk free rate = x = 3.32%
And, the Risk premium = 8.70967741935%
So,
Expected return on market = Risk free rate + Risk premium
= 3.3225806452 + 8.70967741935
= 12.03%
