These questions are based on the graph which shows the demand and production statistics of 5 T.V. companies
What is the difference between the average demand and the average production of the five companies taken together?
Total Demand= 3000+ 600+ 2500+ 1200+ 3300= 10600
So, average demand= $$^{\ \frac{\ 10600}{5}}$$= 2120.
Total Production= 1500+1800+1000+2700+2200= 9200
Average Production= $$^{\ \frac{\ 9200}{5}}$$= 1840.
Therefore difference in average production and average supply= 2120-1840= 280- Option C
