## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the bar diagram and answer the questions. 1. The approximate percentage increase in quantity from 1997 to 1998 was

1. From the given bar diagram , we see
Quantity of sugar bags in 1997 = 130 lakhs
Quantity of sugar bags in 1998 = 150 lakhs
Increase in quantity = 150 - 130 = 20 lakhs

 Percentage increase = Increase in quantity × 100 Quantity of sugar bags in 1997

 Percentage increase = 20 × 100 130

##### Correct Option: E

From the given bar diagram , we see
Quantity of sugar bags in 1997 = 130 lakhs
Quantity of sugar bags in 1998 = 150 lakhs
Increase in quantity = 150 - 130 = 20 lakhs

 Percentage increase = Increase in quantity × 100 Quantity of sugar bags in 1997

 Percentage increase = 20 × 100 130

 Percentage increase = 200 ≈ 15.4% 13

1. Value per bag was minimum in the year

1. According to given bar graph , we have

 Value per lakh bags in year 2001 ⇒ 120 = Rs. 2.4 crores 50

 Value per lakh bags in year 1999⇒ 150 = Rs. 1.5 crores 100

 Value per lakh bags in year 1996⇒ 150 = Rs. 1.25 crores 120

##### Correct Option: C

According to given bar graph , we have

 Value per lakh bags in year 2001 ⇒ 120 = Rs. 2.4 crores 50

 Value per lakh bags in year 1999⇒ 150 = Rs. 1.5 crores 100

 Value per lakh bags in year 1996⇒ 150 = Rs. 1.25 crores 120

 Value per lakh bags in year 1997⇒ 260 = Rs. 2 crores 130

Thus , Value per bag is minimum in the year 1996 .

1. The difference between the bags exported in 1999 and 2000 was

1. On the basis of given graph in question ,
Number of the bags exported in 1999 = 100 lakhs
Number of the bags exported in 2000 = 200 lakhs
Required difference = Number of the bags exported in 2000 - Number of the bags exported in 1999

##### Correct Option: A

On the basis of given graph in question ,
Number of the bags exported in 1999 = 100 lakhs
Number of the bags exported in 2000 = 200 lakhs
Required difference = Number of the bags exported in 2000 - Number of the bags exported in 1999
Required difference = (200 – 100) lakhs = 100 lakhs = 10000000

1. Percentage fall in value from 2000 to 2001 is

1. From the given bar diagram , we see

 Value per lakh bags in year 2000 ⇒ 500 = Rs. 2.5 crore 200

 Value per lakh bags in year 2001 ⇒ 120 = Rs. 2.4 crore 50

Total Decrease = 2.5 - 2.4 = Rs. 0.1 crore
 Percentage decrease = Total Decrease × 100 Value per lakh bags in year 2000

##### Correct Option: E

From the given bar diagram , we see

 Value per lakh bags in year 2000 ⇒ 500 = Rs. 2.5 crore 200

 Value per lakh bags in year 2001 ⇒ 120 = Rs. 2.4 crore 50

Total Decrease = 2.5 - 2.4 = Rs. 0.1 crore
 Percentage decrease = Total Decrease × 100 Value per lakh bags in year 2000

 Percentage decrease = 0.1 × 100 = 4% 2.5

Direction: Study the following graph which shows the production (in thousand) of different items, and answer the questions. 1. The respective ratio between the number of CDs produced by the company in the year 2009 and the number of keyboards produced by the company in the year 2005 is

1. According to given bar graph , we have
Number of CD produced by the company in 2009 = 22500
Number of keyboards produced by the company in 2005 = 25000
Required ratio = Number of CD produced by the company in 2009 : Number of keyboards produced by the company in 2005

##### Correct Option: A

According to given bar graph , we have
Number of CD produced by the company in 2009 = 22500
Number of keyboards produced by the company in 2005 = 25000
Required ratio = Number of CD produced by the company in 2009 : Number of keyboards produced by the company in 2005
∴ Required ratio = 22500 : 25000 = 225 : 250 = 9 : 10
