    On the basis of given graph in question , we have
    The total production of fertilizers in the year 1998 and 2000 = ( 90 + 60 ) = 150
    The total production in the years 1997 and 1999 = ( 80 + 75 ) = 155

    As per the given bar graph in question ,
    Total production of fertilizers in the year 1995, 1997 and 1999 = 70 + 90 + 60 = 220
    Total production of fertilizers in the year 1996, 1998 and 2000 = 80 + 80 + 75 = 235
    Required ratio = Total production of fertilizers in the year 1995, 1997 and 1999 : Total production of fertilizers in the year 1996, 1998 and 2000

    Correct Option: C

    As per the given bar graph in question ,
    Total production of fertilizers in the year 1995, 1997 and 1999 = 70 + 90 + 60 = 220
    Total production of fertilizers in the year 1996, 1998 and 2000 = 80 + 80 + 75 = 235
    Required ratio = Total production of fertilizers in the year 1995, 1997 and 1999 : Total production of fertilizers in the year 1996, 1998 and 2000
    ∴ Required ratio = 220 : 235 = 44 : 47

  1. The difference of the average production of fertilizers in the first three years and the average production in the last three years (in lakh tonnes) is

    On the basis of given graph in question ,
    Production of fertilizers in 1995 = 70
    Production of fertilizers in 1996 = 80
    Production of fertilizers in 1997 = 90
    Production of fertilizers in 1998 = 80
    Production of fertilizers in 1999 = 60
    Production of fertilizers in 2000 = 75
    Sum of production of fertilizers in the first three years = 70 + 80 + 90 = 240 lakh tonnes
    Sum of production of fertilizers in the last three years = 80 + 60 + 75 = 215 lakh tonnes

    Required difference =

    Production of fertilizers in 1998 = 80
    Production of fertilizers in 1999 = 60
    Production of fertilizers in 2000 = 75
    Sum of production of fertilizers in the first three years = 70 + 80 + 90 = 240 lakh tonnes

  1. The ratio of the number of years, in which the trade deficit is above the average deficit, to those years in which the trade deficit is below the average deficit, is








  1. View Hint View Answer Discuss in Forum

    On the basis of given bar graph in question ,
    Sum of deficit from years 1987 to 1995 = 2200 + 3100 + 2100 + 2800 + 2600 + 3600 + 4200 + 2600 = 23200 millions
    Total number of years = 8

    Average deficit =
    23200
    		 = 2900 million
    8

    ∴ Required ratio = Number of years in which the trade deficit is above the average deficit : Number of years in which the trade deficit is below the average deficit

    Correct Option: A

    On the basis of given bar graph in question ,
    Sum of deficit from years 1987 to 1995 = 2200 + 3100 + 2100 + 2800 + 2600 + 3600 + 4200 + 2600 = 23200 millions
    Total number of years = 8

    Average deficit =
    23200
    		 = 2900 million
    8

    ∴ Required ratio = Number of years in which the trade deficit is above the average deficit : Number of years in which the trade deficit is below the average deficit
    ∴ Required ratio = 3 : 5
