Direction: Read the graph and answer the following questions.
-
What is the difference between average demand and average production of computers of the five months taken together?
-
- 400
- 700
- 540
- 260
Correct Option: D
As per the given bar graph , we have
Total demand of computers of the five months = 2500 + 100 + 2000 + 700 + 2800 = 8100
Number of months = 5
| Average demand = | = 1620 | 5 |
Total production of computers of the five months = 1000 + 1300 + 500 + 2200 + 1800 = 6800
Number of months = 5
| Average production = | = 1360 | 5 |
Required difference = Average demand - Average production
∴ Required difference = 1620 – 1360 = 260
