Answer:
The first thing that we need to do in this question is find the total capital of the Group. They get their capital from three sources which are bonds, preferred stock and common stock. We need to find the capital provided by each of these 3 sources and add them up. After that we will see what ratio of capital is provided by preferred stock, and this ratio will be the weight of preferred stock as it related to the firms weighted average cost of capital.
Bonds
1000*980=980,000
Preferred stock = 9700*85= 824,500
Common stock= 43,000*80= 3,440,000
980,000+824,500+3,440,000= 5,244,500
Preferred weight = 824,500/5,244,500= 0.157 = 15.7%
The weight of preferred stock is 15.7%
