作逻辑题 有一点很重要 即分清楚percentage和exact number

本题中一直都在讨论的是相对数字 比率 C怎么能得出二者之间绝对数据有什么可比性呢

这是个数学问题

题目说percentage of households with an annual income （>40000）M > any other country

      percentage of households with an annual income  (>60000) S>  any other country

在4000这条线上M还是最大的 而把标准上升到6000的时候就被S超过了

很明显是在第二个标准除去的那一档里失去了percentage 即在M有人出于4000-6000之间

即B
