Answer:
Expected return = 28%
Explanation:
given data
invests $4,000
share = 200
return = 24%
and
invests = $2000
share = 100
return = 18%
and
invest = $4,000
share = 400
return = 28%
to find out
expected return on this portfolio
solution
we know total investment is
Total investment = 4000+2000+4000
Total investment = 10000
and
Wt. of Sand Corporation shares in the total portfolio= 
= 0.4
Wt. of Water Corporation shares in the total portfolio=
= 0.2
Wt. of Beach Corporation shares in the total portfolio= = 0.4
and
Expected return on the given portfolio is
Expected return = 0.4 × 24% + 0.4 × 18% + 0.4 × 28%
Expected return = 28%
