The six regions in which Techtyx Appliance Company sells appliances are labeled A through F in the graph.

答案是PREP12 a是选20  REP18 a.forth b.E  有看明白的求解释啊

首先谢谢楼主的附件 我找了好久都没找到= =
下面是我的理解 不知道对不对

12题：

"of the Internet users 62 years old or older who used one or more forms of social media" = 1-70% =30%

"users 62 years old or older who used social networking sites" = 6%

==> 6%/30% = 0.2 = 20%


18题：

"The size of each circle and the corresponding number in the circle indicate the proportion of Techtyx customer transactions in that region. "

"The position of each circle’s center relative to the vertical axis shows how many different product types are marketed in the region,
and the position relative to the horizontal axis shows last year’s sales in thousand of euros for the region."

A：”the one with the most Techtyx customer transactions“
就是最大的饼C 对应0.33那个 从饼的圆心看纵坐标 约有33种不同的商品
而C上面的上个饼D、E、F分别对应 40、42、45种商品 都比C(33)大
所以C拥有的商品种类数量(number of different products) 排在第四

B："value of the average transaction" 所指的是单笔交易的额度

假设总共销售的单子数是100 那么E就是5笔单子 销售总额约650K欧元
于是在E区的分部销售中 单笔交易的平均额度就是130K欧元
再看其他几个区 A=500K/29=17.24K；B=250K/8=31.25K；
C=800K/33=24.24K；D=550K/10=55K ；F=900K/15=60K
都小于E的单笔平均额度（130K）

如果不假设交易总数为100而是X 那么A就是0.29X
算法完全一致 结果亦是E最大(13000/X)

请问楼主，你的MBA的题目指的是什么，从哪里找的，有没有PREP全套题目，请指教，感激不尽！
