## Introduction to Data Interpretation

#### Data Interpretation

Direction: Sutdy the following bar graph and answer the questions.

1. The average production of 1996 and 1997 is exactly equal to the average production of the years

1. As per the given bar graph , we see
Total production in 1996 and 1997 = 40 + 60 = 100 ten thousand tonnes
Total production in 1995 and 2001 = 25 + 75 = 100 ten thousand tonnes

##### Correct Option: A

As per the given bar graph , we see
Total production in 1996 and 1997 = 40 + 60 = 100 ten thousand tonnes
Total production in 1995 and 2001 = 25 + 75 = 100 ten thousand tonnes
Hence , correct answer is option A .

1. The number of years, the production of fertilizers was more than average production of the given years is :

1. On the basis of given graph in question ,
Sum of the production of fertilizers = 25 + 40 + 60 + 45 + 65 + 50 + 75 + 80 = 440
Number of given years = 8

 Average production = Sum of the production of fertilizers Number of given years

 Average production = 25 + 40 + 60 + 45 + 65 + 50 + 75 + 80 ten thousand tonnes 8

##### Correct Option: A

On the basis of given graph in question ,
Sum of the production of fertilizers = 25 + 40 + 60 + 45 + 65 + 50 + 75 + 80 = 440
Number of given years = 8

 Average production = Sum of the production of fertilizers Number of given years

 Average production = 25 + 40 + 60 + 45 + 65 + 50 + 75 + 80 ten thousand tonnes 8

 Average production = 440 = 55 ten thousand tonnes 8

Required years ⇒ 1997, 1999, 2001 and 2002

Direction: The following table shows the worldwide production of steel in 1920–1927. Study the table and answer the questions.

1. The average production of steel is (in million tonnes)

1. According to given bar graph , we have
Average production of steel = 77.1 million tonnes

##### Correct Option: C

According to given bar graph , we have
Average production of steel = 77.1 million tonnes
Hence , required answer is 77.1 million tonnes .
