    As per the given pie chart in question ,
    The corresponding angle for cement = 72°
    The corresponding angle for bricks = 54°
    Required ratio = The corresponding angle for cement : The corresponding angle for bricks

    Correct Option: C

    As per the given pie chart in question ,
    The corresponding angle for cement = 72°
    The corresponding angle for bricks = 54°
    Required ratio = The corresponding angle for cement : The corresponding angle for bricks
    Required ratio = 72° : 54° = 4 : 3

    On the basis of given pie chart in question ,
    Corresponding angle for steel = 36°
    ∵ 360° ≡ 100%


    1% =
    100
    360

    Correct Option: A

    On the basis of given pie chart in question ,
    Corresponding angle for steel = 36°
    ∵ 360° ≡ 100%


    1% =
    100
    360

    ∴ 36% ≡ $100 × 36° % = 10%
    360

    According to given pie chart in question ,
    Miscellaneous expenditures amount = $ 12000
    Percent of expenditure on miscellaneous = 2%
    ∵ 2% ≡ $ 12000


    1% =
    12000
    2

    Correct Option: B

    According to given pie chart in question ,
    Miscellaneous expenditures amount = $ 12000
    Percent of expenditure on miscellaneous = 2%
    ∵ 2% ≡ $ 12000


    1% =
    12000
    2

    ∴ 24% ≡ $12000× 24
    2

    Expenditure on canvassing = $ 144000


  1. Royalty on the book is less than canvassing expenditure by

    As per the given pie chart in question ,
    Percent expenditure on Royalty = 24%
    Percent expenditure on canvassing = 12%
    Change in expenditure = 24 - 12 = 12%

    Required percent =
    Change in expenditure
    × 100
    Percent expenditure on Royalty

    Correct Option: B

    As per the given pie chart in question ,
    Percent expenditure on Royalty = 24%
    Percent expenditure on canvassing = 12%
    Change in expenditure = 24 - 12 = 12%

    Required percent =
    Change in expenditure
    × 100
    Percent expenditure on Royalty

    Required percent =
    12
    × 100 = 50%
    24

    As per the given pie chart in question ,
    The cost of printing = $ 16,800
    Corresponding percentage of printing = 42%
    Corresponding percentage of royalty = 12%
    ∵ 42% ≡ $ 16800


    1% =
    16800
    42

    Correct Option: C

    As per the given pie chart in question ,
    The cost of printing = $ 16,800
    Corresponding percentage of printing = 42%
    Corresponding percentage of royalty = 12%
    ∵ 42% ≡ $ 16800


    1% =
    16800
    42

    ∴ 12% ≡ $16800 × 12 = $ 4800
