A.     k/m %

B.     (k-m) %

C.     [100(k-m)]/(100+k) %

D.     [100(k-m)]/(100+m) %

E.      [100(k-m)]/(100+k+m) %

假设前年Price per share =x, 前年earning per share =y 那么去年的price per share 为(1+k%)x,去年的earning per share 为(1+m%)y 求 去年的price per share 与earning per share的比率 比前年的比率增加了多少。

[(1+k%)x]/[(1+m%)y ]/(x/y)再减1

=(1+k%)/(1+m%)再减1

=(k%-m%)/(100-m%)

    [100(k-m)]/(100+m) %

那个k%的百分号要化来化去的,细心一点就ok。

请先搜索

谢谢

题目的意思是价格和股利的比例增长了多少,就是两个的比啊

上面解的很清楚了啊

[(1+k%)x]/[(1+m%)y ]是增长后的

(x/y)是增长前的
