Answer:
6.48%
Step-by-step explanation:
For computing the revised expected return first we have to find out the expected return which is shown below:
Expected return = Beta × Market rate of return
= 0.8 × 0.115
= 0.092 or 9.2%
Now the required expected rate of return if market return changed to 8.10%
Revised Expected return = 0.8 × 0.081
= 6.48%
