## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following graph shows the production of cotton bales of 100 kg each (in lakhs) by different states A, B, C, D and E over the years. Study the graph and answer the following Questions. 1. In which State(s) is there a steady increase in the production of cotton during the given period?

1. From the given bar diagram , we see there is a steady increase in the production of cotton during the given period in states A and C .

##### Correct Option: C

From the given bar diagram , we see there is a steady increase in the production of cotton during the given period in states A and C . Hence , required answer is option C.

1. The production of State C in 2003- 2004 is how many times its production in 2005-2006?

1. According to given bar graph , we have
The production of State C in 2003- 2004 = 6
The production of State C in 2005- 2006 = 15

 Required answer = The production of State C in 2003- 2004 The production of State C in 2005- 2006

##### Correct Option: D

According to given bar graph , we have
The production of State C in 2003- 2004 = 6
The production of State C in 2005- 2006 = 15

 Required answer = The production of State C in 2003- 2004 The production of State C in 2005- 2006

 Required answer = 6 = 0.4 15

Direction: Study the following graph and answer the questions. Number on the top of a bar is the number of TVs. 1. What is the ratio of average demand to average production of companies B and D?

1. On the basis of given graph in question ,
Sum of demand of companies B and D = 1200 + 600 = 1800
Number of companies = 2

 Average demand of companies B and D = Sum of demand of companies B and D = 1800 = 900 Number of companies 2

Sum of production of companies B and D = 2700 + 1800 = 4500
Number of companies = 2
 Average production of companies B and D = Sum of production of companies B and D Number of companies

##### Correct Option: B

On the basis of given graph in question ,
Sum of demand of companies B and D = 1200 + 600 = 1800
Number of companies = 2

 Average demand of companies B and D = Sum of demand of companies B and D = 1800 = 900 Number of companies 2

Sum of production of companies B and D = 2700 + 1800 = 4500
Number of companies = 2
 Average production of companies B and D = Sum of production of companies B and D Number of companies

 Average production of companies B and D = 4500 = 2250 2

∴ Required ratio = 900 : 2250 = 2 : 5

1. Demand of company D is approximately what percent of demand of company E ?

1. According to given bar graph , we have
Demand of company D = 600
Demand of company E = 2500

 Required percentage = Demand of company D × 100 Demand of company E

##### Correct Option: C

According to given bar graph , we have
Demand of company D = 600
Demand of company E = 2500

 Required percentage = Demand of company D × 100 Demand of company E

 Required percentage = 600 × 100 = 24% 2500

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

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

 Average demand = 3300 + 1200 + 3000 + 600 + 2500 5

 Average demand = 10600 = 2120 5

Total production = 2200 + 2700 + 1500 + 1800 + 1000
Number of companies = 5
 Average production = 2200 + 2700 + 1500 + 1800 + 1000 5

##### Correct Option: C

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

 Average demand = 3300 + 1200 + 3000 + 600 + 2500 5

 Average demand = 10600 = 2120 5

Total production = 2200 + 2700 + 1500 + 1800 + 1000
Number of companies = 5
 Average production = 2200 + 2700 + 1500 + 1800 + 1000 5

 Average production = 9200 = 1840 5

&there; Required difference = Average demand : Average production
&there; Required difference = 2120 – 1840 = 280
