In a group of 200 male and female workers, 10 percent of the males smoke, and 49 percent of the females smoke.
Quantity A: Total number of workers who smoke
Quantity B: 59
选项
A、Quantity A is greater.
B、Quantity B is greater.
C、The two quantities are equal.
D、The relationship cannot be determined from the information given.
答案
C
解析
处理这种应用题,先试着把文字描述转换成数学关系。设male worker的数量为x,则female的数量为200-x,Quantity A=0.1x+0.49(200-x)=98-0.39x,x的范围为0<x<200,所以20<Quantity A<98。这是我们能用数学的方法推断出的Quantity A的一个范围。根据这个范围,考生可能错误地选择D。
