Answer:
Consider the following calculations
Explanation:
a) If the weight of risky portfolio is 'y' then weight of T-bill would be (1-y).
Expected return on clients portfolio = weight of risky portfolio x return on risky portfolio + weight of T-bill x return on T-bill
or, 15% = y x 17% + (1 - y) x 7%
or, y = 0.8
weight of risky portfolio = 0.8, weight of T-bill = 0.2
b)
Security	Investment Proportions
T-bill	20% (from part a)
Stock A	80% x 0.27 = 21.6%
Stock B	80% x 0.33 = 26.4%
Stock C	80% x 0.40 = 32%
Total	100%
