Calculation for What is the variance of returns of the portfolio
First step is to calculate the mean
Mean = (20% + 25% + 30%) / 3
Mean =75% / 3
Mean = 25%
Now let calculate the variance of returns of the portfolio
Portfolio variance of returns = {(20 − 25)^2 + (25 − 25)^2 + (30 − 25)^2} / 3
Portfolio variance of returns=25+0+25/3
Portfolio variance of returns=50/3
Portfolio variance of returns= 16.7
Therefore the variance of returns of the portfolio will be 16.7
