Total sales of branch B6 for both years
= 70 + 80
= 150
Total sales of branch B3 for both years
= 95 + 110
= 205
∴ Required percentage
= $$\frac{150}{205} × 100$$
= 73.17%

Total sales of branches B1, B3 and B5 for both the years (in thousands numbers)
= (80 + 105) + (95 + 110) + (75 + 95)
= 560

Required ratio
$$=\frac{\text{Total sales of branch B2 for both years}}{\text{Total sales of branch B4 for both years}}$$
$$\eqalign{ & = \frac{75+65}{85+95} \cr & = \frac{140}{180} \cr & = \frac{7}{9} \cr & = 7:9 \cr} $$

Total sales (in thousand numbers) of branches B1, B3 and B6 in 2000
= 80 + 95 + 70
= 245
Average sales (in thousands number) of branches B1, B3 and B6 in 2000
= $$\frac{245}{3}$$
Total sales (in thousands number) of branches B1, B2 and B3 in 2001
= 105 + 65 + 110
= 280
Average sales (in thousand number) of branches B1, B2 and B3 in 2001
$$\eqalign{ & = \frac{280}{3} \cr & \text{So,Required percentage} \cr & = \frac{\frac{245}{3}}{\frac{280}{3}}\times100\% \cr & = \frac{245}{280}\times100 \cr & = 87.5\% \cr} $$

Total sales of all the six branches (in thousand numbers) for the year 2000
= 80 + 75 + 95 + 85 + 75 + 70
= 480
Average sales of all the six branches (in thousand numbers) for the year 2000
$$\eqalign{ & = \frac{480}{6} \cr & = 80 \cr} $$
