The expected return of the portfolio is $85.
The amount invested in
Stock x = $350
Stock y = $200
Stock Z = Total investment – (Stock x + Stock y)
       = 1000 – (350 + 200) = 450
Therefore, the amount invested in Stock z will be $450
Expected returns from stock = amount invested in Stock x Expected returns (%)
Therefore,
Expected returns from Stock x = 350 × [tex]\frac{8}{100}[/tex] = 28
Expected returns from Stock y = 200 × [tex]\frac{16}{100}[/tex] = 32
Expected returns from Stock z = 450 × [tex]\frac{10}{100}[/tex] = 45
The expected returns from stock x, y and z are $28, $32 and $45 respectively.
The expected return of the portfolio = 28 + 32 + 45 = 85
The expected return of the portfolio is $85 (from all the three stocks).
