这道题为什么不用直接 trailing P/E求解?
P/E=（1-b）*(1+g)/(r-g)=(2.75/5.64)*(1+6%)/(15%-6%)=5.74
问题如下图：
选项：
A. 
B. 
C.

NO.PZ201612170200000301 问题如下 1. Baseon Exhibit 1, the trailing P/E for Centralino of 1 January 2015, ignoring any business-cycle influence, is closest to: A.8.3. B.8.9. C.9.9. B is correct. The trailing P/E ratio is calculatefollows: Stock’s current price/Most recent four quarters’ EPS €50/€5.64 = 8.9 这道题为什么不需要用EPS2014减去优先股部分的earning，算出普通股的EPS，再用P/EPS普通

The trailing P/E ratio is calculatefollows: Stock’s current price/Most recent four quarters’ EPS €50/€5.64 = 8.9如果是用公式算，一般会怎么问呢

NO.PZ201612170200000301 我计算此题步骤如下 Trailing P/E=(1-b)(1+g)/re-g 其中 1、1-b用2014年数据2.75/5.64 2、re=15%,g=6% 3、代入数据，结果为5.74，不同于答案， 请问我是哪里算错了吗？
老师好这题，1）是不是“ ignoring any business-cycle influence”就是指用mostrecentEPS2014的EPS？2）是不是如果不是 ignoring any business-cycle influence的话，就要用2011-2014EPS的平均值来了算？3）是不是如果求leangPE的话，就要用2015的EPS6来算？谢谢。
