Answer 2

Given,

The total number of population$\[ = 1000\]$

The number of persons read MB$\[ = 540\]$

The number of persons read PDI$\[ = 470\]$

The number of persons read both$\[ = 150\]$

Solution,

Formula used, $\[P\left( {A \cup B} \right) = P\left( A \right) + P\left( B \right) - P\left( {A \cap B} \right)\]$

Therefore, the number of persons who do not read either of the two newspapers are

$\[\begin{array}{l} \Rightarrow 1000 - \left[ {540 + 470 - 150} \right]\\ \Rightarrow 1000 - \left[ {1010 - 150} \right]\\ \Rightarrow 1000 - 860\\ \Rightarrow 140\end{array}\]$

Hence, the correct option is (A) i.e. $\[140.\]$
