    According to given pie chart in question ,
    Corresponding percentage of service = 20%
    We have relation between percentage and degree ,
    ∴ 100% ≡ 360°

    ∴ 1% ≡
    360
    100

    Correct Option: C

    According to given pie chart in question ,

    As per the given pie chart in question ,
    Total number of people = 20000
    The percent of maximum number of people involved in agriculture = 33.30%
    The percent of minimum number of people involved in trade = 6.7%
    Difference of corresponding percentages = (33.30 – 6.7)% = 26.6%
    ∴ Required answer = 26.6% of 20000

    Correct Option: D

    As per the given pie chart in question ,
    Total number of people = 20000

    According to given pie chart in question ,
    The price of gold in 2013 = $ 31,500 per 10 gram
    The corresponding angle of year 2013 = 135°
    The corresponding angle of year 2011 = 75°
    ∵ 135° ≡ $ 31500

    Correct Option: B

    According to given pie chart in question ,
    The price of gold in 2013 = $ 31,500 per 10 gram
    The corresponding angle of year 2013 = 135°
    The corresponding angle of year 2011 = 75°
    ∵ 135° ≡ $ 31500

    ∴ 75° ≡ $31500× 75 = $ 17500
    135

    On the basis of given pie chart in question ,
    The corresponding angle of year 2013 = 135°
    The corresponding angle of year 2010 = 45°
    Required ratio = The corresponding angle of year 2010 : The corresponding angle of year 2013

    Correct Option: B

    On the basis of given pie chart in question ,
    The corresponding angle of year 2013 = 135°
    The corresponding angle of year 2010 = 45°
    Required ratio = The corresponding angle of year 2010 : The corresponding angle of year 2013
    Required ratio = 45° : 135° = 1 : 3

    According to given pie chart in question ,
    The corresponding angle of year 2013 = 135°
    The corresponding angle of year 2011 = 75°
    Total Increase = 135° - 75° = 60°

    Required percentage increase =
    Total Increase
    × 100
    The corresponding angle of year 2011

    Correct Option: D

    According to given pie chart in question ,
    The corresponding angle of year 2013 = 135°
    The corresponding angle of year 2011 = 75°
    Total Increase = 135° - 75° = 60°

    Required percentage increase =
    Total Increase
    × 100
    The corresponding angle of year 2011

    Required percentage increase =
    60 × 100
    = 80%
