Question 148

What is the difference (in tonnes) between average demand and average production of the five companies taken together?

Solution

average demand = $$\frac{3000+600+2400+1200+3300}{5}=\frac{10500}{5}=2100$$

average production = $$\frac{1500+1800+900+2700+1500}{5}=\frac{8400}{5}=1680$$

difference = 2100 - 1680 = 420

so the answer is option B.
