What is the difference between average demand and average production of the five companies taken together?
-
- 1400
- 400
- 280
- 138
Correct Option: C
On the basis of given graph in question ,
Total demand = 3300 + 1200 + 3000 + 600 + 2500
Number of companies = 5
| Average demand = | 5 |
| Average demand = | = 2120 | 5 |
Total production = 2200 + 2700 + 1500 + 1800 + 1000
Number of companies = 5
| Average production = | 5 |
| Average production = | = 1840 | 5 |
&there; Required difference = Average demand : Average production
&there; Required difference = 2120 – 1840 = 280
