Answer:
The correct answer 8.83%
Explanation:
The first step is to calculate the market risk premium which will be used late in the calculation of required return
The formula of market risk premium is
(Required return - risk-free rate) ÷ Beta
= (9.5% - 4.2%) ÷ 1.05
= 5.048%
The second step is to calculate the beta of portfolio
= (10 ÷ 15) × 1.05 + (5 ÷ 15) × 0.65
= 0.9167
Required return:
= Risk-free rate + Beta of portfolio × Market risk premium
= 4.2% + 0.9167 × 5.048%
= 8.83%
