Direction: The following table shows the worldwide production of steel in 1920–1927. Study the table and answer the questions.
-
The number of years during which the company has its production less than the average production during 1920–1927 is approximately
-
- 6
- 4
- 3
- 2
Correct Option: B
On the basis of given graph in question ,
Sum of production during 1920–1927 = 71.30 + 43.51 + 67.66 + 76.23 + 77.23 + 88.93 + 91.75 + 100.17
Number of given years = 8
| Average production during 1920 – 1927 = | Number of given years |
| Average production during 1920 – 1927 = |  | 71.30 + 43.51 + 67.66 + 76.23 + 77.23 + 88.93 + 91.75 + 100.17 |  | million tonnes | |
| 8 |
| Average production during 1920 – 1927 = | = 77.1 million tonnes | 8 |
∴ Required years = 1920, 1921, 1922 and 1923
