问题如下：
Compared to Cinnamon’s operating margin in 2017, if it is deemed to have control of Cambridge, its operating margin in 2018 will most likely be:
选项：
A.lower.
B.higher.
C.the same.
解释：
A is correct.
Cambridge has a lower operating margin (88/1,100 = 8.0%) than Cinnamon (142/1,575 = 9.0%). If Cambridge’s results are consolidated with Cinnamon’s, the consolidated operating margin will reflect that of the combined company, or 230/2,675 = 8.6%.
解析 ：operating margin = operating profit / revenue。
2017年该投资属于被动投资，不share result也不合并报表，该ratio分子分母就是投资公司自己的金额。根据表格数据可求得2017 年 Cinnamon 公司的 operating margin = 126/1400 = 9%
2018 年增加投资，根据本题题干要control，则使用acquisition method，需要合并报表，将被投资公司100%的revenue和operating都合并到母公司损益表中，因此2018年增加投资后operating profit=142+88=230，revenue=1575+1100=2675
operating margin = 230/2675 = 8.6%，相比2017年变低了。
如题
