Answer:
The correct answer is option (A).
Explanation:
According to the scenario, the computation of the given data are as follows:
First, we will calculate the Market risk premium, then
Market risk premium = (Required return - Risk free rate ) ÷ beta
= ( 9.50% - 4.20%) ÷ 1.05 = 5.048%
So, now Required rate of return for new portfolio = Risk free rate + Beta of new portfolio × Market premium risk
Where, Beta of new portfolio = (10 ÷ 18.5) × 1.05 + (8.5 ÷ 18.5) × 0.65
= 0.5676 + 0.2986
= 0.8662
By putting the value, we get
Required rate of return = 4.20% + 0.8662 × 5.048%
= 8.57%
