  1. The ratio of total production of fertilizers in the year 1996 and 1997 to that of total production in the year 1995, 1998 and 2000 is








  1. View Hint View Answer Discuss in Forum

    As per the given bar graph in question ,
    Total production of fertilizers in the year 1996 and 1997 = 40 + 60 = 100
    Total production of fertilizers in the year 1995, 1998 and 2000 = 25 + 45 + 50 = 120
    Required ratio = Total production of fertilizers in the year 1996 and 1997 : Total production of fertilizers in the year 1995, 1998 and 2000

    Correct Option: A

    As per the given bar graph in question ,
    Total production of fertilizers in the year 1996 and 1997 = 40 + 60 = 100
    Total production of fertilizers in the year 1995, 1998 and 2000 = 25 + 45 + 50 = 120
    Required ratio = Total production of fertilizers in the year 1996 and 1997 : Total production of fertilizers in the year 1995, 1998 and 2000
    ∴ Required ratio = 100 : 120 = 5 : 6

  1. In which year was the percentage increase in production as compared to the previous year, the maximum?

    On the basis of given bar graph in question , we see
    The production of fertilizer in year 1995 = 25
    The production of fertilizer in year 1996 = 40
    Increase = 40 - 25 = 15
    ⇒ In Year 1996 ,

    Percentage increase =
    15
    		 × 100 = 60%
    25

    The production of fertilizer in year 1996 = 40
    The production of fertilizer in year 1997 = 60
    Increase = 60 - 40 = 20
    ⇒ In Year 1997 ,

    Correct Option: C

    On the basis of given bar graph in question , we see
    The production of fertilizer in year 1995 = 25
    The production of fertilizer in year 1996 = 40
    Increase = 40 - 25 = 15
    ⇒ In Year 1996 ,

    Percentage increase =
    15
    		 × 100 = 60%
    25

    The production of fertilizer in year 1996 = 40
    The production of fertilizer in year 1997 = 60
    Increase = 60 - 40 = 20
    ⇒ In Year 1997 ,
    Percentage increase =
    60 - 40
    		 × 100 = 50%
    40

    Therefore , % increase is maximum in 1996 .

  1. In how many years was the production of fertilizers more than the average production of the given years?

    As per the given bar graph in question ,
    Total production of fertilizers years from 1995-2002 = 25 + 40 + 60 + 45 + 65 + 50 + 75 + 80 = 4400000 tonnes
    Total number of given years = 8

    Average production =
    Total production of fertilizers years from 1995-2002
    Total number of given years

    Correct Option: D

    As per the given bar graph in question ,
    Total production of fertilizers years from 1995-2002 = 25 + 40 + 60 + 45 + 65 + 50 + 75 + 80 = 4400000 tonnes
    Total number of given years = 8

    Average production =
    Total production of fertilizers years from 1995-2002
    Total number of given years

    Average production =
    4400000
    		 tonnes = 550000 tonnes
    8

    ∴ Required years = 1997, 1999, 2001 and 2002.

  1. What was the percentage decline in the production of fertilizers from 1997 to 1998?

    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

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

    Correct Option: C

    The production of fertilizer in year 1997 = 60
    The production of fertilizer in year 1998 = 45
    Decrease = 60 - 45 = 15

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

    Percentage decrease =
    15
    		 × 100 = 25%
    60

  1. In how many of the given years was the production of salt more than the average production of the given years?








  1. View Hint View Answer Discuss in Forum

    As per the given bar graph in question ,
    Total production of salt from 2001 to 2008 = 40 + 30 + 70 + 25 + 55 + 50 + 80 + 90 = 440 × 1000 tonnes = 440000
    Number of years from 2001 to 2008 = 8

    Average production =
    Total production of salt from 2001 to 2008
    		 tonnes
    Number of years from 2001 to 2008

    Average production =
    (40 + 30 + 70 + 25 + 55 + 50 + 80 + 90) × 1000
    		 tonnes
    8

    Correct Option: C

    As per the given bar graph in question ,
    Total production of salt from 2001 to 2008 = 40 + 30 + 70 + 25 + 55 + 50 + 80 + 90 = 440 × 1000 tonnes = 440000
    Number of years from 2001 to 2008 = 8

    Average production =
    Total production of salt from 2001 to 2008
    		 tonnes
    Number of years from 2001 to 2008

    Average production =
    (40 + 30 + 70 + 25 + 55 + 50 + 80 + 90) × 1000
    		 tonnes
    8

    Average production =
    440
    		 × 1000 = 55000 tonnes
    8

    Years having more production than it = 2003, 2007 and 2008
