Answer: 9.25%
Step-by-step explanation:
Risk free rate, Rf = 5% = 0.05
We then subtract the risk free rate of 5% from the expected date of return on market portfolio of 10%. This will be:
= 10% - 5% = 5%
Beta = 0.85
Required return will now be:
= Rf + (Rm-Rf) x Beta
= 5% + (5% × 0.85)
= 5% + 4.25%
= 9.25%
