The total population of the city is estimated to be 14 million. The common readership (in lakhs) is indicated in the given Venn diagram
Solution
Given Readership of newspaper X = 8.7
only X + 2.5 + 0.5 + 1 = 8.7
only X = 4.7
Given Readership of newspaper Y = 9.1
only Y + 2.5 + 1.5 + 0.5 = 9.1
only Y = 4.6
Given Readership of newspaper Z = 5.6
only Z + 0.5 + 1 + 1.5 = 5.6
only Z = 2.6
Number of people who read only one newspaper = 4.7 + 4.6 + 2.6 = 11.9 lakhs
