Answer and Explanation:
Expected return on Equity fund = Treasury bills rate + Expected risk premium = 13.8% + 3.6%
= 17.4%
Expected return portfolio = 80% of Expected return on Equity fund + 20% of Treasury bills rate
= (17.4% x 80%) + (3.6% x 20%)
= 14.64%
Standard deviation portfolio = 80% of standard deviation
80% × 52% = 41.60%
Note: Assume 80% Portfolio in fund and 20% in Treasury bills.
