Total sales of branch B6 for both years is what percent of the total sales of branch B3 for both years?
Answer: A
Total sales of branch B6 = 70 + 80 = 150 thousand.
Total sales of branch B3 = 95 + 110 = 205 thousand.
Required percentage = \(\frac{\text{Sales of B6}}{\text{Sales of B3}} \times 100\)
= \(\frac{150}{205} \times 100 \approx 73.17\)%.
