问题如下图：
选项：
A. 
B. 
C. 
解释：
Current assets ancurrent liability crease the same ammount. Current assets ancurrent liability increase the same ammount. Answer is Current ratio = current assets / current liabilities. Given the ratio is greater thone, the numerator annominator crease the same amount will result in a lower current ratio. 假设ratio是1.5, 同时增加0·5和减少0·5，结果和答案相反啊
假如，2/3 分子和分母同时减去1，得到1/2，那么current ratio 也是呈下降趋势，则B也正确？
我不知道哪里卡壳了比如 3/2 分子分母同时加1，等于4/3 那么 3/2 4/3 啊？
可否从逻辑上下这道题？
