问题 Questions are based on the following data.
[br] In region P, the expense in the category Other was what fraction of the total of the expense in the three non-housing categories?
选项 A、1/10
B、1/6
C、1/5
D、1/4
E、1/3
答案 D
解析 对于同一个region，应采取横向比较。因为总数都是一样的，所以比较比例即可。Other为10％，non-housing包括Transportation：16％，Groceries：14％，0ther：10％。所以占比为10/(16+14+101=1/4，故答案为D。此处参与计算的百分比对应的总量都是P的总支出，所以不需要带着具体的钱数计算。
