1、利润总额=39600-25000-6500-600-800-900=5800
资产平均额=(100000+1200000)/2=1100000
资产利润率=5800/1100000=0.5%
销售利润率=5800/39600=14.65%
成本费用利润率=5800/(25000+6500+600+800+900)=17.16%
权益平均额=(79000+8100)/2=43550
权益报酬率=5800/43550=13.32%
2、财务杠杆系数=EBIT/(EBIT-I)=240/(240-400*10%)=1.2
股票资本成本=8%+1.6*(13%-8%)=16%
债权资本成本=10%*(1-33%)=6.7%
综合资本成本=6.7%*(400/1000)+16%*(600/1000)=12.28%
