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?
~$\frac{k}{m}$~%
(k – m) %
~$\frac{100(k-m)}{100+k}$~%
~$\frac{100(k-m)}{100+m}$~%
~$\frac{100(k-m)}{100+k+m}$~%
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
(1+K%)/(1+m%)-1
=(100+K)%/(100+m)%-1
=(100+k-100-m)%/(100+M)%
=(k-m)/(100+m)
=100(k-m)/(100+m) %
