在一项调查中,有300名受访者被问及是否拥有汽车。如果是,则进一步要求他们提及自己是否拥有汽车或踏板车,或两者兼有。下表中列出了无响应。

GATECS2014Q9

百分之几的受访者不拥有踏板车?
(A) 48
(B) 40
(C) 50
(D) 45答案: (A)
解释:

No. of respondents do not own scooter = 
                        No. of persons who have car alone + 
                        No. of persons who don't have both.
In men, 40 + 20 = 60 and
In women 34 + 50 = 84.
Total 60 + 84 = 144 .
Now the percentage is, (144/300) *100 = 48
