Correct Answer - Option 1 : 20 %
Given:
In a survey it was found that 65 % people listen TV news
Read newspapers, = 40 %
Follow both= 25 %
Formula Used:
Percentage = (actual/Total) × 100
Calculation:
Let total no. of people in a survey =100
65% people listen TV news
No. of people listen TV news = (65 × 100) / 100 = 65
40% read newspapers, = (40 × 100) /100 = 40
25 % people use both TV and newspaper.
no. of people = (25 × 100 ) / 100 = 25
Then, no of people listen only TV news = 65-25 = 40
no of people read only TV news = 40 - 25 = 15
no. of people neither listen nor read news =100 - (40+15+25) = 20
percentage of people = (20 × 100 ) / 100 = 20 %
∴ Percentage of people neither listen TV news nor read newspapers is 20 %
