EXPLANATION
Portfolio Consisits of Stock A and Risk Free security .
Beta of Stock A is 1.5 and Beta of Risk Free Security is 0 . (Risk free securities has a beta of 0 as they are not affected by market Movements)
We want to achieve a portfolio Beta of .75
Weight of stock A = Wa
Weight of risk free security = Wrf
Wa * 1.5 + Wrf * 0 = .75
Wa = .5
Wrf = 1-.5 = .5
Expected return of portfolio = Wa * 15 + Wrf * 3
.5 * 15 + .5 * 3 = 9%
