1) From the Given Census, Calculate the Total Number of Population of Children in the Years 2011 and 2001.

Step 1:In the year 2011.

Number of male children = 10,75,440
Number of female children = 9,37,014
Total number of children = 10,75,440 + 9,37,014

<sup>10,75,440
+ 9,37,014</sup>_20,12,454

Therefore, there were Twenty lakh twelve thousand four hundred and fifty-four children in 2011.

Step 2:In the year 2011.

Number of male children = 10,79,618
Number of female children = 9,37,231
Total number of children = 10,79,618 + 9,37,231

<sup>10,75,440
+ 9,37,231</sup>_20,16,849

Therefore, there were Twenty lakh sixteen thousand eight hundred and forty-nine children in 2001.

2) In Which Year Did the Children Population Were Less and by How Much?

Number of children population in the year 2011 = 20,12,454
Number of children population in the year 2001 = 20,16,849
As 20,12,454 < 20,16,849, the children population was less in 2011.
Subtract 20,12,454 from 20,16,849 to get the difference.

<sup>20,16,849
- 20,12,454</sup>_4,395

Hence, the year 2011 has Four thousand three hundred ninety-five fewer children population than the year 2001.

3) How Many Female Literates Were There in the Years 2011 and 2001?

Step 1:In the year 2011.

Total number of literates = 1,27,37,767
Number of male literates = 71,94,856
Number of female literates = 1,27,37,767 – 71,94,856

<sup>1,27,37,767
- 71,94,856</sup>_55,42,911

Therefore, there were Fifty-five lakh forty-two thousand nine hundred eleven female literates in 2011.

Step 2:In the year 2011.

Total number of literates = 96,64,764
Number of male literates = 57,00,847
Number of female literates = 96,64,764 – 57,00,847

<sup>96,64,764
- 57,00,847</sup>_39,63,917

Therefore, there were Thirty-nine lakh sixty-three thousand nine hundred seventeen female literates in 2001.

4) How Many Illiterates Were There in the Year 2001?

Step 1:

Number of male populations = 76,07,234
Number of female populations = 62,43,273
Total population = 76,07,234 + 62,43,273

<sup>76,07,234
+ 62,43,273</sup>_1,38,50,507

Step 2:

Total number of populations = 1,38,50,507
Total number literates = 96,64,764
Number of illiterates = 1,38,50,507 – 96,64,764

<sup>1,38,50,507
- 96,64,764</sup>_41,85,743

Hence, there were Forty-one lakh eighty-five thousand seven hundred forty-three illiterates in 2001.
