Correct Answer: 280
Solution :
As per the graph,
The number of given companies = 5
The total demand of the five companies = 3000 + 600 + 2500 + 1200 + 3300 = 10600
The average demand of the five companies = $\frac{10600}{5}$ = 2120
The total production of the five companies = 1500 + 1800 + 1000 + 2700 + 2200 = 9200
The average demand of the five companies = $\frac{9200}{5}$ = 1840
The required difference = 2120 – 1840 = 280
Hence, the correct answer is 280.
