表格显示了广播电台 KAMC 一项调查的部分结果。接受调查的男性中有百分之多少收听这个电台?

The table shows some of the results of a survey by radio station KAMC. What percentage of the males surveyed listen to the station?

3939

4848

5252

5555

7575

答案:E
知识点:数据与图表解读百分数
难度评级:1000
解答:

接受调查的男性总数是调查总人数减去女性人数:20096=104200-96=104

这些男性中 2626 人不收听,所以 10426=78104-26=78 名男性收听。所求百分比为 78104100%=75%\dfrac{78}{104}\cdot 100\%=75\%

所以正确答案是 E

The total number of males surveyed is the total number surveyed minus the number of females surveyed: 20096=104200-96=104.

Of those males, 2626 do not listen, so 10426=78104-26=78 males listen. The desired percentage is 78104100%=75%\dfrac{78}{104}\cdot 100\%=75\%.

Thus, E is the correct answer.
