    According to given bar graph , we have
    Number of families in daily income interval 800-900 = 40
    Number of families in daily income interval 900-1000 = 15
    Required number of families = Number of families in daily income interval 800-900 + Number of families in daily income interval 900-1000

    Correct Option: B

    According to given bar graph , we have
    Number of families in daily income interval 800-900 = 40
    Number of families in daily income interval 900-1000 = 15
    Required number of families = Number of families in daily income interval 800-900 + Number of families in daily income interval 900-1000
    Required number of families = 40 + 15 = 55

    As per the given above bar graph , we have
    Number of families who have daily income interval 0-100 = 15
    Number of families who have daily income interval 100-200 = 10
    Number of families who have daily income interval 200-300 = 40
    Number of families who have daily income interval 300-400 = 5
    Number of families who have daily income interval 400-500 = 20
    Number of families who have daily income interval 500-600 = 30
    Number of families who have daily income interval 600-700 = 15
    Number of families who have daily income 700-800 = 10
    Number of families who have daily income interval 800-900 = 40
    Number of families who have daily income interval 900-1000 = 15

    Correct Option: C

    Number of families who have daily income interval 0-100 = 15
    Number of families who have daily income interval 100-200 = 10
    Number of families who have daily income interval 200-300 = 40
