Answer:
Step-by-step explanation:
Given
For ABC
rE = 15%
rD = 7.5%
D/E = 3/7
rE = rA + (rA-rD)*(D/E)
15 = rA + (rA-7.5)*(3/7)
105 = 7rA + 3rA - 22.5
10rA = 127.5
Hence,
rA = 12.75%
Now,
Weighted average cost of capital is the rate of return required from the firm. Irrespective of its capital structure.
WACC = (D/V)* rD + (E/V)*rE
Since, D/E = 2/7
So, D/V = D/(D+E) = 3/10
SImilary, E/V = 7/10
Hence,
WACC = (3/10)*7.5 + (7/10)*15
= 12.75%
c
Since this is perfect capital market and firms are competitors with different capital structure.
According to MM proposition the Asset return and WACC of two identical firms with different capital structure are same
Hence
rA of XYZ = 12.75%
d
similarly as question c
WACC of XYZ = 12.75%
E AND F is solved in the attached below
