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:

請問大大

解答是 D, 小弟我真的是百思不解為何 increased price 要減去 earning price? 然後earning price 要加上100?

肯定有個套路在裡面請高手相助

感激!

本来股价同收益的比为p/e，增加后为p(1+%k)/e(1+m%)，增长的百分比就是（p(1+k%)/e(1+m%)）/(p/e)-1
