    According to given bar graph , we have
    The total sales of branch B2 for both years = 75 + 65 = 140 thousands
    The total sales of branch B4 for both years = 85 + 95 = 180 thousands
    Required ratio = The total sales of branch B2 for both years : The total sales of branch B4 for both years

    Correct Option: D

    According to given bar graph , we have
    The total sales of branch B2 for both years = 75 + 65 = 140 thousands
    The total sales of branch B4 for both years = 85 + 95 = 180 thousands
    Required ratio = The total sales of branch B2 for both years : The total sales of branch B4 for both years
    Required ratio = 140 : 180 = 7 : 9


  1. Total sale of branches B1, B3 and B5 together for both the years (in thousand) is

    From the given bar diagram , we see
    Total sale of branches B1, B3 and B5 together for both the years = (80 + 105 + 95 +110 + 75 + 95) thousands

    Correct Option: D

    From the given bar diagram , we see
    Total sale of branches B1, B3 and B5 together for both the years = (80 + 105 + 95 +110 + 75 + 95) thousands = 560 thousands
    Hence , required answer is option D.
