As per the given bar graph , we have
Total sale of branches B1, B2 and B3 in 2001 = 105 +65 + 110 = 280 thousands
Number of given branches = 3Average sale of branches B1, B2 and B3 in 2001 = 105 +65 + 110 3 Average sale of branches B1, B2 and B3 in 2001 = 280 thousand 3
Total sale of branches B1, B3 and B6 in 2000 = 80 + 95 + 70 = 245 thousands
Number of given branches = 3Average sale of branches B1, B3 and B6 in 2000 = 
80 + 95 + 70 
Thousand 3 Average sale of branches B1, B3 and B6 in 2000 = 245 Thousand 3

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 yearsCorrect 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
