Directions(6-10): Study the following table carefully to answer the questions that follow. The table shows the online and offline contestants taking part in a survey from four villages and total contestant who have not completed the survey (online and offline) Note-1: Total contestants in a village= Online contestants + Offline contestants 2: Total contestants in a village=Contestants who complete the survey + contestants who do not complete survey


6. In village A, if the number of online and offline contestants who didn’t complete the survey are equal, then online contestants from village A who completed the survey are what percent (approximate) more than offline contestants who completed the survey from the same village?
   25%
   20%
   35%
   15%
   30%
   Option C
   Offline contestant in village A = 350 44 56  = 275
   Online contestant who complete the survey = 350 – 61 = 289
   Offline contestant who complete the survey = 275 – 61 = 214
   Required % = (289 – 214)/214*100 ≈ 35%
   
   
    



7. Total number of contestants from village C who completed the survey are how much more or less than total number of contestants who completed the survey from village B?
   800
   826
   820
   841
   850
   Option D
   Total no. of contestant from village C who complete the survey = [465 + (465/60*40)]- 180 = 667
   Total no. of contestant from village B who complete the survey = [560 + (560/35*65)] – 92 = 1508
   Required number = 1508 – 667 = 841
