## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the Bar diagram carefully and answer the questions.
The Bar diagram shows the trends of foreign direct investment (FDI) into India from all over the World (in Rs. crores). 1. The sum of FDI of 1992 and 1993 is

1. According to given bar graph , we have
FDI in 1992 = \$ 5.7 billion
FDI in 1993 = \$ 10.15 billion
Sum of FDI of 1992 and 1993 = FDI in 1992 + FDI in 1993

##### Correct Option: B

According to given bar graph , we have
FDI in 1992 = \$ 5.7 billion
FDI in 1993 = \$ 10.15 billion
Sum of FDI of 1992 and 1993 = FDI in 1992 + FDI in 1993 = \$ (5.7 + 10.15) billion = \$ 15.85 billion.
The sum of FDI of 1992 and 1993 is \$ 15.85 billion.

Direction: Sutdy the following bar graph and answer the questions. 1. The percentage decline in the production of fertilizers from 1997 to 1998 is :

1. On the basis of given graph in question ,
The production of fertilizer in year 1997 = 60
The production of fertilizer in year 1998 = 45
Decrease = 60 - 45 = 15

 Required percentage decrease = Decrease × 100 The production of fertilizer in year 1997

 Required percentage decrease = 60 - 45 × 100 60

##### Correct Option: B

On the basis of given graph in question ,
The production of fertilizer in year 1997 = 60
The production of fertilizer in year 1998 = 45
Decrease = 60 - 45 = 15

 Required percentage decrease = Decrease × 100 The production of fertilizer in year 1997

 Required percentage decrease = 60 - 45 × 100 60

 Required percentage decrease = 1500 = 25% 60

1. The percentage increase in production as compared to previous year is maximum in year :

1. From the given bar diagram , we see
The production of fertilizers in 1997 = 60 ( in tonnes )
The production of fertilizers in 1996 = 40 ( in tonnes )
Increase = The production of fertilizers in 1997 - The production of fertilizers in 1996 = 60 - 40 = 20

 Percentage increase in 1997 = 20 × 100 = 50% 40

The production of fertilizers in 1995 = 25 ( in tonnes )
The production of fertilizers in 1996 = 40 ( in tonnes )
Increase = The production of fertilizers in 1996 - The production of fertilizers in 1995 = 40 - 25 = 15

##### Correct Option: B

From the given bar diagram , we see
The production of fertilizers in 1997 = 60 ( in tonnes )
The production of fertilizers in 1996 = 40 ( in tonnes )
Increase = The production of fertilizers in 1997 - The production of fertilizers in 1996 = 60 - 40 = 20

 Percentage increase in 1997 = 20 × 100 = 50% 40

The production of fertilizers in 1995 = 25 ( in tonnes )
The production of fertilizers in 1996 = 40 ( in tonnes )
Increase = The production of fertilizers in 1996 - The production of fertilizers in 1995 = 40 - 25 = 15
 Percentage increase in 1996 = Increase × 100 The production of fertilizers in 1995

 Percentage increase in 1996 = 15 × 00 = 60% 25

1. The percentage increase in production of fertilizers in 2002 compared to that in 1995 is :

1. According to given bar graph , we have
The production of fertilizers in 2002 = 80
The production of fertilizers in 1995 = 25
Increase = 80 - 25 = 55

 Required percentage increase = Increase × 100 The production of fertilizers in 1995

##### Correct Option: A

According to given bar graph , we have
The production of fertilizers in 2002 = 80
The production of fertilizers in 1995 = 25
Increase = 80 - 25 = 55

 Required percentage increase = Increase × 100 The production of fertilizers in 1995

 Required percentage increase = 55 × 100 = 220% 25

1. The average production of 1996 and 1997 is exactly equal to the average production of the years

1. As per the given bar graph , we see
Total production in 1996 and 1997 = 40 + 60 = 100 ten thousand tonnes
Total production in 1995 and 2001 = 25 + 75 = 100 ten thousand tonnes

##### Correct Option: A

As per the given bar graph , we see
Total production in 1996 and 1997 = 40 + 60 = 100 ten thousand tonnes
Total production in 1995 and 2001 = 25 + 75 = 100 ten thousand tonnes
Hence , correct answer is option A .
