    As per the given bar graph , we have
    The number of working women in the year 2006 = 50 millions
    The number of working women in the year 2010 = 85 millions
    Required ratio = The number of working women in the year 2006 : The number of working women in the year 2010

    Correct Option: D

    As per the given bar graph , we have
    The number of working women in the year 2006 = 50 millions
    The number of working women in the year 2010 = 85 millions
    Required ratio = The number of working women in the year 2006 : The number of working women in the year 2010
    ∴ Required ratio = 50 : 85 = 10 : 17

    From the given bar diagram , we see
    The number of non-working women in the year 2010 = 35 millions
    The number of working women in the year 2010 = 85 millions
    Total number of working and non-working women in the year 2010 =85 + 35 = 120 millions

    Required percentage =
    The number of non-working women in the year 2010
    × 100
    Total number of working and non-working women in the year 2010

    Correct Option: C

    From the given bar diagram , we see
    The number of non-working women in the year 2010 = 35 millions
    The number of working women in the year 2010 = 85 millions
    Total number of working and non-working women in the year 2010 =85 + 35 = 120 millions

    Required percentage =
    The number of non-working women in the year 2010
    × 100
    Total number of working and non-working women in the year 2010

    Required percentage =
    35
