Final answer:
Using the formula: Risk-adjusted discount rate = Risk-free rate + Beta * Market risk premium.
The risk-adjusted discount rate for Project A is 0.164 and for Project B is 0.116.
The company should choose Project B as it has a higher risk-adjusted NPV.
Step-by-step explanation:
To calculate the risk-adjusted discount rate for each project using the CAPM, we need to use the formula:
Risk-adjusted discount rate = Risk-free rate + Beta * Market risk premium
For Project A:
Risk-adjusted discount rate for Project A = 0.05 + 1.2 * 0.08
= 0.164
For Project B:
Risk-adjusted discount rate for Project B = 0.05 + 0.8 * 0.08
= 0.116
To determine which project the company should choose based on the risk-adjusted net present value (NPV), we need to calculate the NPV for each project.
For Project A:
NPV for Project A = (1,00,000 / (1 + 0.164)^1) + (1,50,000 / (1 + 0.164)^2) + (2,00,000 / (1 + 0.164)^3) - 3,00,000
= 31,883.75
For Project B:
NPV for Project B = (80,000 / (1 + 0.116)^1) + (1,20,000 / (1 + 0.116)^2) + (1,80,000 / (1 + 0.116)^3) - 3,00,000
= 1,38,149.80
Based on the risk-adjusted NPV criteria, the company should choose Project B as it has a higher NPV.
