Answer:
12.95%
Explanation:
Expected return of portfolio (rP) = wX*rX + wY*rY +wZ*rZ
wX= weight of X =25% or 0.25 as a decimal
rX = return of X = 10% or 0.10 " "
wY = weight of Y =40% or 0.40 " "
rY = return of Y = 13% or 0.13 " "
wZ = weight of Z = 35% or 0.35 " "
rZ = return of Z = 15% or 0.15 " "
Next, plug in the numbers to the above formula;
(rP) = (0.25*0.10) +(0.40*0.13) +(0.35 * 0.15)
= 0.025 + 0.052 + 0.0525
= 0.1295
Therefore expected return of portfolio = 12.95%
