Percentage of persons who do not read newspaper A = 100% - 50% = 50% Percentage of persons who do not read newspaper B = 100% - 40% = 60% Percentage of persons who don't read any newspaper neither A nor B = 20% From the following chart. Total percentage who read both A and B newspaper = 100% - 30%-20%-40% = 10% Let the total number of people be x, then x × (10/100) = 500 x = 500 x 10 = 5000 The total number of persons are 5000.
