Sales of B1 for both years = 80 + 105 = 185
Sales of B2 for both years =Â 75 + 65 = 140
Sales of B3 for both years =Â 95 + 110 = 205
Sales of B4 for both years = 85 + 95 = 180
Sales of B5 for both years =Â 75 + 95 = 170
Sales of B6 for both years =Â 70 + 80 = 150
Total sales for both years = 185 + 140 + 205 + 180 + 170 + 150 = 1030
Avg. sales for both years = $$\frac {1030}{6} = 171.666$$
