## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the graph and answer the following questions.

1. What is the difference between average demand and average production of the companies taken together?

1. On the basis of given graph in question ,
Total demand of the companies = 3000 + 600 + 2500 + 1200 + 3300 = 10600
Number of companies = 5

 ∴ Average demand = Total demand of the companies Number of companies

 ∴ Average demand = 10600 = 2120 5

Total production of the companies = 1500 + 1800 + 1000 + 2700 + 2200 = 9200
 ∴ Average production = Total production of the companies Number of companies

##### Correct Option: C

On the basis of given graph in question ,
Total demand of the companies = 3000 + 600 + 2500 + 1200 + 3300 = 10600
Number of companies = 5

 ∴ Average demand = Total demand of the companies Number of companies

 ∴ Average demand = 10600 = 2120 5

Total production of the companies = 1500 + 1800 + 1000 + 2700 + 2200 = 9200
 ∴ Average production = Total production of the companies Number of companies

 ∴ Average production = 10600 = 1840 5

Required difference = Average demand : Average production
Required difference = 2120 – 1840 = 280

1. What percent of the demand of company C is that of the company B?

1. According to given bar graph , we have
The demand of company C = 2500 units
The demand of company B = 600 units

 Required percentage = The demand of company B × 100 The demand of company C

##### Correct Option: C

According to given bar graph , we have
The demand of company C = 2500 units
The demand of company B = 600 units

 Required percentage = The demand of company B × 100 The demand of company C

 Required percentage = 600 × 100 = 24% 2500

1. Which of the above States is the largest producer of wheat?

1. As per the given bar graph , we have
Uttar Pradesh (UP) produces 16 million tonnes of wheat that is largest.

##### Correct Option: D

As per the given bar graph , we have
Uttar Pradesh (UP) produces 16 million tonnes of wheat that is largest. Hence , required answer is Uttar Pradesh (UP) .

1. In which of the above states the total production of rice and wheat is the least?

1. According to given bar graph , we have
Production of rice least in Maharashtra = 3 million tonnes
Production of wheat least in Maharashtra = 2 million tonnes

##### Correct Option: C

According to given bar graph , we have
Production of rice least in Maharashtra = 3 million tonnes
Production of wheat least in Maharashtra = 2 million tonnes
Total production of rice and wheat is least in Maharashtra 5 million tonnes .Hence , required answer is Maharashtra .

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
