                X increased by m percent, where k is greater than m.  By what percent did the ratio of price per share to earnings per share increase, in terms of k and m?

A.       %

B.      (k – m) %

C.      [100(k – m)] / (100 + k) %

D.     [100(k – m)] / (100 + m) %

E.      [100(k – m)] / (100 + k + m) %

Answer: D

请问NN, 怎么算出来的? 主要对划出来的句字不理解. 赚了的比例和涨了的比例有什么区别?

同问!!

就是股票的加个涨了k%，股利增了m%，问股价/股利的比例增加了多少

[p（1+k%）]/[e(1+m%)]-p/e

Last year the price per share of Stock X increased by k percent and the earnings per share of Stock
                X increased by m percent, where k is greater than m.  By what percent did the ratio of price per share to earnings per share increase, in terms of k and m?

A.       %

B.      (k – m) %

C.      [100(k – m)] / (100 + k) %

D.     [100(k – m)] / (100 + m) %

E.      [100(k – m)] / (100 + k + m) %

the ratio of price per share 1+k%)

the ratio of earnings per share 1+m%)

((1+k%)-(1+m%))/(1+m%)=[100(k – m)] / (100 + m) %

earnings per share :每股盈利

顶一下，谁能帮普及一下这道题的背景知识么？

每股股价和每股盈利的关系？

题目基本作对了，但基本是不知道怎么做对的。谢谢NN
