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 :

    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

    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

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








  1. View Hint View Answer Discuss in Forum

    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
