    As per the given above table , we can see
    Total production of scooters of all factories = 115 + 108 + 149 + 102 + 101 = 575
    Number of given years = 5

    Required Average =
    Total production of scooters of all factories
    Number of given years

    Correct Option: A

    As per the given above table , we can see
    Total production of scooters of all factories = 115 + 108 + 149 + 102 + 101 = 575
    Number of given years = 5

    Required Average =
    Total production of scooters of all factories
    Number of given years

    Required Average =
    575
    		= 115
    5

    Clearly, it was in the year 1985.

    On the basis of given table in question ,
    Total population in 1992 = 160998
    Total population in 1991 = 153922 – 5337 = 148585
    ∴ Increase in population in 1992 over 1991 = Total population in 1992 - Total population in 1991

    Correct Option: B

    On the basis of given table in question ,
    Total population in 1992 = 160998
    Total population in 1991 = 153922 – 5337 = 148585
    ∴ Increase in population in 1992 over 1991 = Total population in 1992 - Total population in 1991
    Increase in population in 1992 over 1991 = 160998 – 148585 = 12413

    On the basis of given table in question ,
    Total population in 1990 = 153922
    Decrease in 1991 = 5337
    Total population in 1991 = Total population in 1990 - Decrease in 1991 = 153922 – 5337 = 148585
    Total population of men and children in 1991 = 69395 + 21560 = 90955
    Number of women in 1991 = Total population in 1991 – total population of men and children in 1991

    Correct Option: A

    On the basis of given table in question ,
    Total population in 1990 = 153922
    Decrease in 1991 = 5337
    Total population in 1991 = Total population in 1990 - Decrease in 1991 = 153922 – 5337 = 148585
    Total population of men and children in 1991 = 69395 + 21560 = 90955
    Number of women in 1991 = Total population in 1991 – total population of men and children in 1991 = 148585 – 90955 = 57630

    Number of children in 1989 = Total population in 1989 – Total population of men and women

    Correct Option: A

    According to given table, we have
    Total population in 1989 = 158577
    Total population of men and women = 70391 + 62516 = 132907
