In a town, 45% population read magazine A, 55% read magazine B, 40% read magazine C, 30% read magazines A and B, 15% read magazines B and C, 25% read magazines A and C; and 10% read all the three magazines. What percentage do not read any magazine?
Answer: 20
Explanation
Number of the population who read the magazine
= (45 + 55 + 40) – (30 + 25 +15) + 10
= 140 – 70 + 10
= 80%
Number of the population who do not read magazines = 100 – 80 = 20%
