    From the given pie chart in question ,
    The cost of cement = $ 5000
    Corresponding angle for cement = 72°
    Corresponding angle for labour expenses = 90°
    ∵ 72° ≡ $ 5000


    1° =
    5000
    72

    Correct Option: B

    From the given pie chart in question ,
    The cost of cement = $ 5000
    Corresponding angle for cement = 72°
    Corresponding angle for labour expenses = 90°
    ∵ 72° ≡ $ 5000


    1° =
    5000
    72

    ∴ 90% ≡ $5000 × 90° = $ 6250
    72°


  1. The ratio of cement and bricks used in the construction is :

    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


  1. The percentage of steel used in the construction of the house is

    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


Direction: Study the pie-chart and answer the questions. The pie-chart given below shows the expenditure incurred in bringing out a book by a publisher.

  1. If miscellaneous expenditures amount to $ 12000, the expenditure on canvassing will be

    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%
