    From the given bar diagram , we see
    Sales of branches B1 in both years = 80 + 105 = 185 thousand
    Sales of branches B3 in both years = 95 + 110 = 205 thousand
    Sales of branches B5 in both years = 75 + 95 = 170 thousand

    Correct Option: D

    From the given bar diagram , we see
    Sales of branches B1 in both years = 80 + 105 = 185 thousand
    Sales of branches B3 in both years = 95 + 110 = 205 thousand
    Sales of branches B5 in both years = 75 + 95 = 170 thousand
    Total sales of branches B1, B3 and B5 for both the years = ( 185 + 205 + 170 ) thousand = 560 thousand

    According to given bar graph , we have
    Total sales of all the branches in 2009 = 80 + 75 + 95 + 85 + 75 + 70 = 480
    Number of given branches = 6

    Required Average =
    Total sales of all the branches in 2009
    Number of given branches

    Correct Option: C

    According to given bar graph , we have
    Total sales of all the branches in 2009 = 80 + 75 + 95 + 85 + 75 + 70 = 480
    Number of given branches = 6

    Required Average =
    Total sales of all the branches in 2009
    Number of given branches

    Average sales of all the branches in 2009 =
    480
    		 = 80 thousand

    From the given bar diagram , we see
    Total sales of branch B6 for both the years = 70 + 80 = 150 thousand
    Total sales of branch B3 for both the years = 95 + 110 = 205 thousand
    According to question ,
    x% of Total sales of branch B3 for both the years = Total sales of branch B6 for both the years

    ∴ 205 ×
    x

    Correct Option: B

    From the given bar diagram , we see
    Total sales of branch B6 for both the years = 70 + 80 = 150 thousand
    Total sales of branch B3 for both the years = 95 + 110 = 205 thousand
    According to question ,
    x% of Total sales of branch B3 for both the years = Total sales of branch B6 for both the years

    ∴ 205 ×
    x
    		 = 150
