    According to given bar graph , we have
    Sum of the per acre yield = 80 + 120 + 132 + 120 + 160 + 200 = 812
    Number of countries = 6

    Required average =
    Sum of the per acre yield
    Number of countries

    Required average = 80 + 120 + 132 + 120 + 160 + 200 kg.
    6

    Correct Option: D

    According to given bar graph , we have
    Sum of the per acre yield = 80 + 120 + 132 + 120 + 160 + 200 = 812
    Number of countries = 6

    Required average =
    Sum of the per acre yield
    Number of countries

    Required average = 80 + 120 + 132 + 120 + 160 + 200 kg.
    6

    Required average =
    812
    =

Direction: Study the following bar graph carefully to answer the questions.

  1. The yield per acre produced by Bangladesh is what per cent of the total yield per acre produced by all countries?

    On the basis of given graph in question ,
    Total product per acre = 490 + 322 = 812 quintal
    The yield per acre produced by Bangladesh = 120

    ∴ Required percent =
    The yield per acre produced by Bangladesh
    × 100
    Total product per acre

    Correct Option: C

    On the basis of given graph in question ,
    Total product per acre = 490 + 322 = 812 quintal
    The yield per acre produced by Bangladesh = 120

    ∴ Required percent =
    The yield per acre produced by Bangladesh
    × 100
    Total product per acre

    Required percent =
    120
    × 100 ≈ 14.8%
    812


  1. If the yield per acre is arranged in ascending order, then what is the difference between the yield per acre of first three countries and last three countries?

    From the given bar diagram , we see
    Ascending order of yield per acre : 82, 120, 120, 130, 160, 200
    The yield per acre of first three countries = 130 + 160 + 200 = 490
    The yield per acre of last three countries = 82 + 120 + 120 = 322
    ∴ Required difference = The yield per acre of first three countries – The yield per acre of last three countries

    Correct Option: A

    From the given bar diagram , we see
    Ascending order of yield per acre : 82, 120, 120, 130, 160, 200
    The yield per acre of first three countries = 130 + 160 + 200 = 490
    The yield per acre of last three countries = 82 + 120 + 120 = 322
    ∴ Required difference = The yield per acre of first three countries – The yield per acre of last three countries
    Required difference = (490 – 322) quintals = 168 quintals


  1. The yield per acre of India is what percent more than that of Pakistan?

    According to given bar graph , we have
    The yield per acre of India = 200
    The yield per acre of Pakistan = 160
    Total Change = 200 - 160 = 40

    Required percent =
    Total Change
    × 100
    The yield per acre of Pakistan

    Correct Option: A

    According to given bar graph , we have
    The yield per acre of India = 200
    The yield per acre of Pakistan = 160
    Total Change = 200 - 160 = 40

    Required percent =
    Total Change
    × 100
    The yield per acre of Pakistan

    Required percent =
    40
    × 100 = 25%
    160

    From the given bar diagram , we see
    Total students in year 2006 = 170
    Students who passed in year 2006 = 140

    Pass percentage :Year 2006 ⇒
    140
    × 100 ≈ 82.35 ;
    170

    Total students in year 2007 = 190
    Students who passed in year 2007 = 150
    Pass percentage : Year 2007 ⇒
    150
    × 100 ≈ 78.94 ;
    190

    Correct Option: C

    From the given bar diagram , we see
    Total students in year 2006 = 170
    Students who passed in year 2006 = 140

    Pass percentage :Year 2006 ⇒
    140
    × 100 ≈ 82.35 ;
    170

    Total students in year 2007 = 190
    Students who passed in year 2007 = 150
    Pass percentage : Year 2007 ⇒
    150
    × 100 ≈ 78.94 ;
    190

    Total students in year 2008 = 240
    Students who passed in year 2008 = 180
    Pass percentage : Year 2008 ⇒
    180
    × 100 = 75%
    240

    Hence , correct answer is 2007 year .
