问题如下：
Analyst collected the information about ABC company in the following table：
ABC company has 20 percent interest in the equity of Golden company, beginning of investment is 150 and ending investment is 196. Golden company reported 2,150 revenue and 550 in net income, its average total assets is 1,780. Please calculate the ABC’s asset turnover ratio if excluding the investment in associates:
选项：
A. 0.95
B. 0.89
C. 0.91
解释：
A is correct.
考点：investment in associates
解析：
asset turnover ratio=revenue/average total assets
我们先需要把investment从ABC公司的Asset中减去，因为这里用的都是average，所以我们也计算一个平均数，（196+150）/2=173
所以asset turnover ratio=5677/(6125-173)=0.95
分母减去investment的平均数我可以理解，但是分子分母为什么不加上100%的子公司golden的revenue和asset？答案只是母公司单独的 asset turnover啊？为什么不合并？
