Q18: 
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.  k/m %
B.  (k-m) %
C.  [100(k-m)]/(100+k) %
D.  [100(k-m)]/(100+m) %
E.   [100(k-m)]/(100+k+m) %
Answer:  D

我对题意的理解是：每股价格上涨了K%，每股收益上涨了M%，求每股价格比每股收益？

我觉得通过题目条件无法求解，对答案D也看不明白，请大家指点一二。
