Study the following graph carefully to answer these questions given below it.
What is the difference between the average demand and the average production of the five companies taken together ?
Average demand of all companies = $$\frac{(3000+600+2500+1200+3300)}{5}=\frac{10600}{5}=2120$$
Average production of all companies = $$\frac{(1500+1800+1000+2700+2200)}{5}=\frac{9200}{5}=1840$$
=> Required difference = $$2120-1840=280$$
=> Ans - (C)
