The table gives three factors to be considered when choosing

User-friendly 56%
Fast response time 48%
Bargain prices 42%

The table gives three factors to be considered when choosing an Internet service provider and the percent of the 1,200 respondents to a survey who cited that factor as important. If 30 percent of the respondents cited both “user-friendly” and “fast response time”, what is the maximum possible number of respondents who cited “bargain prices,” but neither “user-friendly” nor “fast response time?”


A. 312
B. 336
C. 360
D. 384
E. 420

Now Total Correspondants – 100%

Hence….  100 = 56 + 48 + 42 – (30) – (Other associations of B…)

Other associations of B… = 16% = 0.16 * 1200 = 192

Now Overall Respondents of B = 0.42 * 1200 = 504.

 Only B Respondent’s = 504 – 192 = 312

Ans : A
