您好,解答如下
1.
保本量=40000/(5-4)=10000
息税前利润=100000*(5-4)-40000=60000
2.
保本量=40000/(5-4)=10000
息税前利润=100000*(1+10%)*(5-4)-40000=70000
息税前利润增长率(70000-60000)/60000=0.1667
销量敏感系数=0.1667/10%=1.67
3.
保本量=40000/(5*110%-4)=26667
息税前利润=100000*(5*110%-4)-40000=110000
息税前利润增长率=(110000-60000)/60000=0.833
单位变动成本敏感系数=0.833/10%=8.83
4.
保本量=400000/(5-4*10%)=28571
息税前利润=100000*(5-4*90%)-40000=100000
息税前利润增长率=(100000-60000)/60000=0.667
单位变动成本敏感系数=0.667/10%=6.67
5.
保本量=40000*(1-10%)/(5-4)=36000
息税前利润=100000*(5-4)-40000*90%=64000
息税前利润变动率=(64000-60000)/60000=0.067
固定成本敏感系数=0.067/10%=6.7%
