Answer:
11.20%
Explanation:
In this question, we apply the Capital Asset Pricing Model (CAPM) formula which is shown below
Expected rate of return = Risk-free rate of return + Beta of market risk × Market rate risk + Beta of interest rate risk × interest rate risk )
= 3.5% + 1 × 9% + 1 × -1.3%
= 3.5% + 9% - 1.3%
= 11.20%
Since in this question, two betas is given for each type of risk, so the calculation is done on that basis only which is shown above.
