    According to given table, we have
    Total production of Rice in given years = 270 + 420 + 350 + 400 + 560 = 2000
    Number of given years = 5
    Total production of barley in given years = 250 + 440 + 320 + 380 + 410 = 1800
    Number of given years = 5

    Required difference =
    2000
    -
    1800
    = 400 – 360
    55

    Correct Option: D

    According to given table, we have
    Total production of Rice in given years = 270 + 420 + 350 + 400 + 560 = 2000
    Number of given years = 5
    Total production of barley in given years = 250 + 440 + 320 + 380 + 410 = 1800
    Number of given years = 5

    Required difference =
    2000
    -
    1800
    = 400 – 360
    55

    Required difference = 40 million tonnes


  1. In the year 2003 – 2004, the increase in production was maximum over the previous year for :

    On the basis of given table in question ,
    Production of Rice in 2003 – 2004 = 560 million tonnes
    Production of Rice in 2002 – 2003 = 400 million tonnes
    Increase = 560 - 400 = 160 million tonnes

    Percentage increase in Rice =
    160
    × 100 = 40%
    400

    Production of Cereals in 2003 – 2004 = 690 million tonnes
    Production of Cereals in 2002 – 2003 = 500 million tonnes
    Increase = 690 - 500 = 190 million tonnes

    Correct Option: A

    On the basis of given table in question ,
    Production of Rice in 2003 – 2004 = 560 million tonnes
    Production of Rice in 2002 – 2003 = 400 million tonnes
    Increase = 560 - 400 = 160 million tonnes

    Percentage increase in Rice =
    160
    × 100 = 40%
    400

    Production of Cereals in 2003 – 2004 = 690 million tonnes
    Production of Cereals in 2002 – 2003 = 500 million tonnes
    Increase = 690 - 500 = 190 million tonnes
    Percentage increase in Cereals =
    190
    × 100 = 38%
    500

    Hence , required answer is Rice .



  1. During the period 1999 - 2000 to 2003 – 2004, x percent of the total production is production of wheat. The value of x is about :

    As per the given above table , we see
    Total production :
    Wheat ⇒ 3700 million tonnes
    Rice ⇒ 2000 million tonnes
    Barley ⇒ 1800 million tonnes
    Other cereals ⇒ 2400 million tonnes
    Total productions of food- grains = 3700 + 2000 + 1800 + 2400 = 9900 million tonnes
    According to question ,
    x% of the total production = Production of wheat
    ⇒ x% × 9900 = 3700

    Correct Option: B

    As per the given above table , we see
    Total production :
    Wheat ⇒ 3700 million tonnes
    Rice ⇒ 2000 million tonnes
    Barley ⇒ 1800 million tonnes
    Other cereals ⇒ 2400 million tonnes
    Total productions of food- grains = 3700 + 2000 + 1800 + 2400 = 9900 million tonnes
    According to question ,
    x% of the total production = Production of wheat
    ⇒ x% × 9900 = 3700

    ∴ x =
    3700
    × 100 = 37.4
    9900


  1. In 2002 – 2003, the percentage increase in the production of barley as compared to the previous year was :

    According to given table, we have
    Production of barley in 2002-2003 = 380 million tonnes
    Production of barley in 2001-2002 = 320 million tonnes
    Increase in production = 380 - 320 = 60 million tonnes

    Percent increase =
    Increase in production
    × 100
    Production of barley in 2001-2002

    Correct Option: C

    According to given table, we have
    Production of barley in 2002-2003 = 380 million tonnes
    Production of barley in 2001-2002 = 320 million tonnes
    Increase in production = 380 - 320 = 60 million tonnes

    Percent increase =
    Increase in production
    × 100
    Production of barley in 2001-2002

    Percent increase =
    60
    × 100 = 18.75%
    320

    As per the given above table , we see
    Total number of people who have monthly income below ₹ 5000 = 162 + 271 + 123 + 52 = 608
    Total number of people who have monthly income between ₹ 5000 - ₹ 10000 = 13 + 285 + 206 + 82 = 586
    Total number of people who have monthly income above ₹ 10000 = 21 + 209 + 325 + 187 = 742
    ∴ Total number of people surveyed = Total number of people who have monthly income below ₹ 5000 + Total number of people who have monthly income between ₹ 5000 - ₹ 10000 + Total number of people who have monthly income above ₹ 10000

    Correct Option: D

    As per the given above table , we see
    Total number of people who have monthly income below ₹ 5000 = 162 + 271 + 123 + 52 = 608
    Total number of people who have monthly income between ₹ 5000 - ₹ 10000 = 13 + 285 + 206 + 82 = 586
    Total number of people who have monthly income above ₹ 10000 = 21 + 209 + 325 + 187 = 742
    ∴ Total number of people surveyed = Total number of people who have monthly income below ₹ 5000 + Total number of people who have monthly income between ₹ 5000 - ₹ 10000 + Total number of people who have monthly income above ₹ 10000
    Total number of people surveyed = 608 + 586 + 742 = 1936
