Questions are based on the following data.
[br] For the region in which the range of the dollar amounts of the four expense categories was least, what percent of total living expense was the Transportation expense in that region?
选项
A、10%
B、15%
C、16%
D、17%
E、20%
答案
E
解析
首先此题需要确定题目中描述的是哪个region。range指的是极差,代表本区域最大值和最小值的差,如Region T,是Housing(最大值)和Groceries(最小值)的差,为1200×(50%-16%)=408,再如Region R,是Housing(最大值)和Other(最小值)的差,为1300 X(64%-8%)=728。同样的方法,我们得知P的极差约为500,Q约为567,S约为700,U约为795,所以最小的是T。对于Region T,Transportation占的比例为20%。故答案为E。此题求极差较为繁琐,但实际上在考试中可以合理掌握技巧,省掉部分计算。我们知道Region T的极差为1200×34%,因此像R这种1300×56%的不需计算直接跳过,因为它肯定比前者大。只有合理掌握简化运算的技巧,才能快速拿到必得的分数。
