उत्तर

(1) The total number of news papers published in Hindi, English, Urdu, Punjabi and Bengali is

=3700+ 3400+ 700+ 200+ 1100
=9100.

(2) The total number of news papers published is

= 700 +400 +1000 + 200 +1400 +1400 + 700 +1100 +3400 +1100

=14,400 

The number of news papers published in Hindi is 3700. The percentage of published Hindi news papers is

`3700/14400 xx 100`

`3700/144`

=25.7% .

(3) The number of news papers published in English and Urdu are 3400 and 700 respectively. Hence, the excess of the number of news papers published in English over those published in Urdu is

3400-700

=2700

(4) According to the length of the 5th and 6th bars from the top, the number of news papers published in Marathi and Malayalam are same. According to the length of the 1st and 3rd bars from the bottom, the number of news papers published in Bengali and Gujrati are same.

(5) According to the length of the 4th bar from the top, the smallest number of news papers published in the language Punjabi.

(6) According to the length of the 4th bar from the bottom, the largest number of news papers published in the language Hindi.

(7) The languages in which the number of published news papers is greater than or equal to 2500 are English and Hindi. Among the languages Hindi and English, the language in which the number of published news papers is less than or equal to 3500 is English. Hence, the language is English.

(8) (a) The number of news papers published in Malayalam and Marathi together is

1400+1400

=2800

The number of news papers published in English is 3400. Clearly, 2800 is less than 3400. Hence, the statement is true.

(b) The number of news papers published in Telugu and Tamil are 400 and 1000 respectively. Clearly 400is not greater than 1000. Hence, the statement is false.
