Direction: Study the graph and answer the following questions.
-
What is the difference between average demand and average production of the companies taken together?
-
- 1400
- 400
- 280
- 138
Correct Option: C
On the basis of given graph in question ,
Total demand of the companies = 3000 + 600 + 2500 + 1200 + 3300 = 10600
Number of companies = 5
| ∴ Average demand = | Number of companies |
| ∴ Average demand = | = 2120 | 5 |
Total production of the companies = 1500 + 1800 + 1000 + 2700 + 2200 = 9200
| ∴ Average production = | Number of companies |
| ∴ Average production = | = 1840 | 5 |
Required difference = Average demand : Average production
Required difference = 2120 – 1840 = 280
