    Required number = percent of persons below 26 years x total number of persons

    Correct Option: A

    As per above given table , we have
    Given :- total number of persons = 4200
    percent of persons below 26 years = ( 30 + 17.75 ) = 47.75%
    Required number = percent of persons below 26 years x total number of persons

    = 4200 x 47.75 = 2005.50 = 2006 approx
    100

  1. If there are 10 million people in the age group 56 years and above, what is the difference between the number of people in the age groups 16–25 and 46–55?

    Given :- difference between the Percent of people in the age groups 16–25 and 46–55 = 3.50%
    Required. difference in the population

    =Total number of people in the age group 56 years and above x 3.50
    percentage of people in the age group 56−65

    Correct Option: A

    Given :- Difference between the Percent of people in the age groups 16–25 and 46–55 = 3.50
    percentage of people in the age group 56−65 = 5.12%
    Total number of people in the age group 56 years and above = 10 million
    Required difference in the population

    =Total number of people in the age group 56 years and above x 3.50
    percentage of people in the age group 56−65

    =10 x 3.50 ≈ 6.8 million
    5.12

    ∵ Number of people in the age group 56 − 65

    =Total number of people age below 36 years x percentage of people in the age group 56−65
    65

    Correct Option: B

    Given :- percentage of people in the age group 56−65 = 5.12
    Total number of people age below 36 years = 200 million
    ∵ Number of people in the age group 56−65

    =Total number of people age below 36 years x percentage of people in the age group 56-65
    65

    =200 x 5.12 ≈ 15.75
    65

  1. If the difference between the number of people in the age groups 46–55 and 26–35 is 11.75 million, then total population of State is approximately

    Total population =difference between the number of people in the age groups 46–55 and 26–35 x 100
    difference between the percentage of people in the age groups 46–55 and 26–35

    Correct Option: B

    Given :- difference between the number of people in the age groups 46–55 and 26–35 = 11.75 million
    difference between the percentage of people in the age groups 46–55 and 26–35 = 17.25 - 14.25 = 3 million

    Total population =difference between the number of people in the age groups 46–55 and 26–35 x 100
    difference between the percentage of people in the age groups 46–55 and 26–35

    = 11.75 x 100 ≈ 391.67 million
