    On the basis of given graph in question ,
    The production of food grains in the year 1984 = 15 thousand tonnes
    The production of food grains in the year 1985 = 30 thousand tonnes
    Increase = 30 - 15 = 15 thousand tonnes

    Percentage increase =
    Increase
    		 × 100
    The production of food grains in the year 1984

    Correct Option: D

    On the basis of given graph in question ,
    The production of food grains in the year 1984 = 15 thousand tonnes
    The production of food grains in the year 1985 = 30 thousand tonnes
    Increase = 30 - 15 = 15 thousand tonnes

    Percentage increase =
    Increase
    		 × 100
    The production of food grains in the year 1984

    Percentage increase =
    15
    		 × 100 = 100%
    15

  1. The difference between the production of food grains in the years 1981 and 1985 is

    As per the given bar graph , we have
    The production of food grains in the year 1981 = 35 thousand tonnes
    And the production of food grains in the year 1985 = 30 thousand tonnes
    Required difference = The production of food grains in the year 1981 - The production of food grains in the year 1985

    Correct Option: C

    As per the given bar graph , we have
    The production of food grains in the year 1981 = 35 thousand tonnes
    And the production of food grains in the year 1985 = 30 thousand tonnes
    Required difference = The production of food grains in the year 1981 - The production of food grains in the year 1985 = 35 - 30 = 5 thousand tonnes
    Required difference = 5000 tonnes

  1. The sum of the production of food grains in the years 1982 and 1984 is equal to that in the year :

    According to given bar graph , we have
    The production of food grains in the year 1982 = 20 thousand tonnes
    And the production of food grains in the year 1984 = 15 thousand tonnes
    Total foodgrain production in 1982 and 1984 = (20 + 15) thousand tonnes = 35 thousand tonnes = Production in 1981

    Correct Option: B

    According to given bar graph , we have
    The production of food grains in the year 1982 = 20 thousand tonnes
    And the production of food grains in the year 1984 = 15 thousand tonnes
    Total foodgrain production in 1982 and 1984 = (20 + 15) thousand tonnes = 35 thousand tonnes = Production in 1981
    Hence , required answer is 1981 .

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 absolute difference in FDI to India between 1996 and 1997 is








  1. View Hint View Answer Discuss in Forum

    As per the given bar graph ,
    FDI in 1997 = 31.36 billion
    and FDI in 1996 = 24.23 billion
    Required difference = FDI in 1997 - FDI in 1996

    Correct Option: B

    As per the given bar graph ,
    FDI in 1997 = 31.36 billion
    and FDI in 1996 = 24.23 billion
    Required difference = FDI in 1997 - FDI in 1996
    Required difference = $ (31.36 – 24.23) billion = $ 7.13 billion

  1. The ratio of investment in 1997 to the average investment is








  1. View Hint View Answer Discuss in Forum

    On the basis of given graph in question ,
    Sum of investment in 1992 - 1992 = 5.7 + 10.15 + 20.16 + 10.22 + 24.23 + 31.36
    Number of given years = 6

    Average investment = 5.7 + 10.15 + 20.16 + 10.22 + 24.23 + 31.36 billion
    6

    Correct Option: A

    On the basis of given graph in question ,
    Sum of investment in 1992 - 1992 = 5.7 + 10.15 + 20.16 + 10.22 + 24.23 + 31.36
    Number of given years = 6

    Average investment = 5.7 + 10.15 + 20.16 + 10.22 + 24.23 + 31.36 billion
    6

    Average investment = 101.82 = 16.97 billion
    6

    ∴ Required ratio = 31.36 : 16.97
    ∴ Required ratio ≈ 2 : 1
