Let's draw a chart using the information from the above bar graph:

Language Number of Newspapers Published

Urdu 700

Telugu 400

Tamil 1000

Punjabi 200

Marathi 1400

Malayalam 1400

Hindi 3700

Gujarati 1100

English 3400

Bengali 1100

(i) Total number of newspapers published in Hindi, English, Urdu, Punjabi and Bengali = 3700 + 3400 + 700 + 200 + 1100 = 9100

(ii) Number of newspapers published in Hindi = 3700
Total number of newspapers published = 700 + 400 + 1000 + 200 + 1400 + 1400 + 3700 + 1100 + 3400 + 1100 = 14400
∴ Percentage of Hindi newspaper published $= \frac{3700}{14400} \times 100 %$
= 25.69%
≃ 25.7%
