Given:

40% of the Delhites read Times of India

50% of the Delhites read the Hindustan Times

10% of the Delhites read both newspapers

Formula used:

Percentage of people who read either newspaper = Percentage who read Times of India + Percentage who read Hindustan Times - Percentage who read both newspapers

Percentage of people who read neither newspaper = 100% - Percentage of people who read either newspaper

Calculation:

Percentage of people who read either newspaper = 40% + 50% - 10%

⇒ Percentage of people who read either newspaper = 80%

Percentage of people who read neither newspaper = 100% - 80%

⇒ Percentage of people who read neither newspaper = 20%

∴ The correct answer is option 3.
