## Introduction to Data Interpretation

#### Data Interpretation

Direction: The bar diagram below shows the production of potatoes (in quintals) from the year 2000 to 2006. Study the diagram and answer the following questions. 1. Considering the average production during this period, the number of years in which the production is above average is :

1. As per the given bar graph ,
Sum of the production of potatoes = 1244 + 1085 + 720 + 1640 + 1240 + 1345 + 1560 = 8834
Number of given years = 7

 Average production = Sum of the production of potatoes Number of given years

##### Correct Option: C

As per the given bar graph ,
Sum of the production of potatoes = 1244 + 1085 + 720 + 1640 + 1240 + 1345 + 1560 = 8834
Number of given years = 7

 Average production = Sum of the production of potatoes Number of given years

 Average production = 8834 = 1262 quintals 7

Years of more than average production = 2003, 2005 and 2006 .
Hence , required answer is 3.

Direction: The graph shows the production of wheat in different years of a particular State. Study the graph and answer questions. 1. The total production from the year 1995 to 1998 (in quintals) is

1. On the basis of given graph in question , we find total production from the year 1995 to 1998 :
Required total production = (1200 + 600 + 500 + 1000) quintals

##### Correct Option: D

On the basis of given graph in question , we find total production from the year 1995 to 1998 :
Required total production = (1200 + 600 + 500 + 1000) quintals = 3300 quintals

1. The year which had the percentage of decrease vis-a-vis its previous year in production as 131/3 % is

1. According to given bar graph , we have
Production in 1999 = 1500 quintal
Production in 2000 = 1300 quintal
Decrease = Production in 1999 - Production in 2000 = 1500- 1300 = 200 quintal

 Percentage decrease = Decrease × 100 Production in 1999

 Percentage decrease = 200 × 100 1500

##### Correct Option: C

According to given bar graph , we have
Production in 1999 = 1500 quintal
Production in 2000 = 1300 quintal
Decrease = Production in 1999 - Production in 2000 = 1500- 1300 = 200 quintal

 Percentage decrease = Decrease × 100 Production in 1999

 Percentage decrease = 200 × 100 1500

 Percentage decrease = 40 = 13 1 % 3 3

1. The percentage increase in production of wheat from 1997-1998 is

1. As per the given bar graph ,
The production of wheat in year 1997 = 500
The production of wheat in year 1998 = 1000
Increase = The production of wheat in year 1998 - The production of wheat in year 1997 = 1000 - 500 = 500

 Percentage increase = Increase × 100 The production of wheat in year 1997

##### Correct Option: A

As per the given bar graph ,
The production of wheat in year 1997 = 500
The production of wheat in year 1998 = 1000
Increase = The production of wheat in year 1998 - The production of wheat in year 1997 = 1000 - 500 = 500

 Percentage increase = Increase × 100 The production of wheat in year 1997

 Percentage increase = 500 × 100 = 100% 500

1. The year in which the production reached maximum is

1. On the basis of given graph in question ,
The production reached maximum is 1500 quintals in years 1999 .

##### Correct Option: C

On the basis of given graph in question ,
The production reached maximum is 1500 quintals in years 1999 . Hence , correct answer is option C .
