## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following graph shows the production of wheat flour (in 1000 tonnes) by three companies X, Y and Z over the years. Study the graph and answer the questions. 1. What is the percentage increase in the production of company Y from 2002 to 2003?

1. On the basis of given graph in question ,
The production of company Y in 2002 = 350 (in 1000 tonnes )
The production of company Y in 2003 = 450 (in 1000 tonnes )
Increase = 450 - 350 = 100 (in 1000 tonnes )

 Required percentage increase = Increase × 100 = 100 % The production of company Y in 2002 7

##### Correct Option: A

On the basis of given graph in question ,
The production of company Y in 2002 = 350 (in 1000 tonnes )
The production of company Y in 2003 = 450 (in 1000 tonnes )
Increase = 450 - 350 = 100 (in 1000 tonnes )

 Required percentage increase = Increase × 100 = 100 % The production of company Y in 2002 7

 Required percentage increase = 14 2 % 7

1. What is the ratio of the average production of company X in the period 2002-2004 to the average production of company Y in the same period?

1. From the given bar diagram , we see
Total production of company X in the period 2002-2004 = 250 + 500 + 400 = 1150
Total production of company Y in the period 2002-2004 = 350 + 400 + 500 = 1250
Number of given years = 3

 Required ratio = 250 + 500 + 400 : 350 + 400 + 500 3 3

##### Correct Option: C

From the given bar diagram , we see
Total production of company X in the period 2002-2004 = 250 + 500 + 400 = 1150
Total production of company Y in the period 2002-2004 = 350 + 400 + 500 = 1250
Number of given years = 3

 Required ratio = 250 + 500 + 400 : 350 + 400 + 500 3 3

Required ratio = 1150 : 1250 = 23 : 25

1. What is the difference between the production of company Z in 2004 and company Y in 2000 (in thousand tonnes)?

1. According to given bar graph , we have
The production of company Z in 2004 = 350 × thousand tonnes
And The production of company Y in 2000 = 250 × thousand tonnes
Required difference = (350 – 250) × thousand tonnes

##### Correct Option: A

According to given bar graph , we have
The production of company Z in 2004 = 350 × thousand tonnes
And The production of company Y in 2000 = 250 × thousand tonnes
Required difference = (350 – 250) × thousand tonnes
Required difference = 100 thousand tonnes

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. The number of States for which the production of cotton in 2005- 2006 is less than or equal to the preceding year is

1. From the given bar diagram , we see
The production of cotton in state B in 2005- 2006 = 21 lakh
The production of cotton in state B in 2005- 2006 = 7 lakh

##### Correct Option: B

From the given bar diagram , we see
The production of cotton in state B in 2005- 2006 = 21 lakh
The production of cotton in state B in 2005- 2006 = 7 lakh
Hence , Required states are B and E.

1. How many kg of cotton was produced by State C during the given period?

1. According to given bar graph , we have
Cotton production in State C in 2003 - 04 = 6 lakhs
Cotton production in State C in 2004 - 05 = 11 lakhs
Cotton production in State C in 2005 - 06 = 15 lakhs
Total cotton production in State C = (6 + 11 + 15) lakhs × 100 kg

##### Correct Option: A

According to given bar graph , we have
Cotton production in State C in 2003 - 04 = 6 lakhs
Cotton production in State C in 2004 - 05 = 11 lakhs
Cotton production in State C in 2005 - 06 = 15 lakhs
Total cotton production in State C = (6 + 11 + 15) lakhs × 100 kg = 320000000 kg
