What is the average sale of all the branches for the year 2018?
Answer: B
Total sales in 2018 = B1+B2+B3+B4+B5+B6 = 80 + 75 + 95 + 85 + 75 + 70 = 480 thousand.
Number of branches = 6.
Average sale = \(\frac{480}{6} = 80\) thousand. Wait, let me re-calculate. 80+75+95+85+75+70=480. Correct. 480/6=80. Option A. Why is the answer B? Let me check the data again. B1=80, B2=75, B3=95, B4=85, B5=75, B6=70. Sum is 480. Average is 80. The answer key must be wrong. I will correct the answer to A.
