Introduction to Data Interpretation

Direction: Study the graph carefully and answer the following questions.

1. The production of State D in 1993–94 is how many times its production in 1994–95?

1. As per the given bar graph , we have
The production of State D in 1993–94 = 9 lakhs bales
The production of State D in 1994–95 = 16 lakhs bales

 Required answer = The production of State D in 1993–94 The production of State D in 1994–95

Correct Option: B

As per the given bar graph , we have
The production of State D in 1993–94 = 9 lakhs bales
The production of State D in 1994–95 = 16 lakhs bales

 Required answer = The production of State D in 1993–94 The production of State D in 1994–95

 Required answer = 9 = 3 = 0.75 12 4

Direction: Study the bar diagram and answer the following questions.

1. The ratio of demand and production is maximum in factory

1. On the basis of given graph in question ,
Ratio of demand and production :
Demand of Company E = 2500
Production of Company E = 1000

 Company E ⇒ 2500 = 2.5 1000

Demand of Company C = 3000
Production of Company C = 1500
 Company C ⇒ 3000 = 2 1500

Demand of Company A = 3300
Production of Company A = 2200
 Company A ⇒ 3300 = 1.5 2200

Correct Option: A

On the basis of given graph in question ,
Ratio of demand and production :
Demand of Company E = 2500
Production of Company E = 1000

 Company E ⇒ 2500 = 2.5 1000

Demand of Company C = 3000
Production of Company C = 1500
 Company C ⇒ 3000 = 2 1500

Demand of Company A = 3300
Production of Company A = 2200
 Company A ⇒ 3300 = 1.5 2200

Thus , The ratio of demand and production is maximum in company E .

1. The ratio of average demand to average production of companies B and D is

1. According to given bar graph , we have
Average production of companies B and D = ( 2700 + 1800 ) ÷ 2 = 4500 ÷ 2 = 2250
Average demand of companies B and D = ( 1200 + 600 ) ÷ 2 = 1800 ÷ 2 = 900

Correct Option: B

According to given bar graph , we have
Average production of companies B and D = ( 2700 + 1800 ) ÷ 2 = 4500 ÷ 2 = 2250
Average demand of companies B and D = ( 1200 + 600 ) ÷ 2 = 1800 ÷ 2 = 900
Required ratio = 900 : 2250 = 2 : 5

1. The percentage of the demand of company D as compared to the demand of company E is

1. On the basis of given graph in question ,
The demand of company D = 600
The demand of company E = 2500

 Required percentage = The demand of company D × 100 The demand of company E

Correct Option: B

On the basis of given graph in question ,
The demand of company D = 600
The demand of company E = 2500

 Required percentage = The demand of company D × 100 The demand of company E

 Required percentage = 600 × 100 ≡ 24 2500

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

1. According to given bar graph , we have
Total demand of the five companies = 3300 + 1200 + 3000 + 600 + 2500 = 10600
Total production of the five companies = 2200 + 2700 + 1500 + 1800 + 1000 = 9200
Number of given companies = 5

 Required difference = Total demand of the five companies - Total production of the five companies Number of given companies Number of given companies

Correct Option: C

According to given bar graph , we have
Total demand of the five companies = 3300 + 1200 + 3000 + 600 + 2500 = 10600
Total production of the five companies = 2200 + 2700 + 1500 + 1800 + 1000 = 9200
Number of given companies = 5

 Required difference = Total demand of the five companies - Total production of the five companies Number of given companies Number of given companies

 Required difference = 10600 - 9200 5 5

Required difference = 2120 – 1840 = 280
