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) %

假设原来的ratio：R1=P/E

去年的ratio：R2=P(100+k)/[E(100+m)]

percent of increase R2-R1)/R1

在换算成百分比也就是乘以100-》D

要你用k和m表达今年的价格和收益比
楼上的牛人啊

Hint: E/P= E'*(1+m%)/P'*(1+k%)

谢谢各位大牛，我当时没有理解“ratio of price per share to earnings per share increase”这句话
