不可以用变形后公式ebit/ebit-interest这个公式吗？

完全可以用！
但是注意再推导这个公式的时候，分子分母的△EBIT是约掉的了。
所以EBIT/EBIT - Interest这个公式里面的EBIT是变动前的数据。
本题中就是360,000/(360,000 - 120,000)
这么算下来答案就是1.5。
视频里的推导：（Leverage这一讲11分钟开始）

那dol变形后的那个公式里存在用变动前的数据这个问题吗？
发亮_品职助教 · 2018年10月01日
两个公式情况是一样的！要么按照定义式的变动百分比计算；要么按照变形式计算，变形式的数据也是用变动前的。视频推导公式可以看出来,在Leverage这一讲的5分钟之后。
