## Introduction to Data Interpretation

#### Data Interpretation 1. What fraction of rice is produced by Haryana of the total production of rice by all the above States?

1. As per the given bar graph , we have
Production of Haryana of rice = 2 million tonnes
Total production of rice = 7 + 8 + 4 + 3 + 2 = 24 million tonnes

 Haryana’s share = Production of Haryana of rice Total production of rice

##### Correct Option: B

As per the given bar graph , we have
Production of Haryana of rice = 2 million tonnes
Total production of rice = 7 + 8 + 4 + 3 + 2 = 24 million tonnes

 Haryana’s share = Production of Haryana of rice Total production of rice

 Haryana’s share = 2 = 1 24 12

1. Which of the above states is the largest producer of rice?

1. On the basis of given graph in question , we see that the bar of West Bengal is the largest.

##### Correct Option: B

On the basis of given graph in question , we see that the bar of West Bengal is the largest. Hence , West Bengal is the largest producer of rice .

1. Which of the above states is least producer of wheat?

1. From the given bar diagram , we see that the bar of West Bengal (W.B.) is lowest.

##### Correct Option: B

From the given bar diagram , we see that the bar of West Bengal (W.B.) is lowest. So , West Bengal ( W.B.) state is least producer of wheat . Hence , correct answer is option B .

Direction: Student’s strength of a college in Arts, Science and Commerce from 2004-05 to 2007- 08 sessions are shown in the following bar graph. Study the graph and answer the questions. 1. The % increase in Science students in 2007-08 over 2006-07 was

1. As per the given bar graph , we have
Number of Science students in 2007-08 = 500
Number of Science students in 2006-07 = 450
Increase = 500 - 450 = 50

 Percentage increase in Science students = Increase × 100 Number of Science students in 2006-07

 Percentage increase in Science students = 50 × 100 450

##### Correct Option: B

As per the given bar graph , we have
Number of Science students in 2007-08 = 500
Number of Science students in 2006-07 = 450
Increase = 500 - 450 = 50

 Percentage increase in Science students = Increase × 100 Number of Science students in 2006-07

 Percentage increase in Science students = 50 × 100 450

 Percentage increase in Science students = 100 = 11.1% 9

1. The ratio of average number of students in Arts to the average number of students in Commerce is

1. On the basis of given graph in question ,
Total number of students in arts = 600 + 550 + 550 + 700 = 2400
Total number of students in commerce = 200 + 250 + 300 + 250 = 1000
Number of given years = 4
Required Ratio = Average number of students in Arts : Average number of students in commerce

##### Correct Option: A

On the basis of given graph in question ,
Total number of students in arts = 600 + 550 + 550 + 700 = 2400
Total number of students in commerce = 200 + 250 + 300 + 250 = 1000
Number of given years = 4
Required Ratio = Average number of students in Arts : Average number of students in commerce

 Required Ratio = 2400 : 1000 4 4

Required Ratio = 24 : 10 = 12 : 5
