    The corresponding angle of expenditure on food = 150°
    The corresponding angle of expenditure on clothes = 30°
    Required ratio = The corresponding angle of expenditure on food : The corresponding angle of expenditure on clothes

    Correct Option: C

    As per the given pie chart in question ,
    The corresponding angle of expenditure on food = 150°
    The corresponding angle of expenditure on clothes = 30°
    Required ratio = The corresponding angle of expenditure on food : The corresponding angle of expenditure on clothes
    Required ratio = 150° : 30°= 5 : 1

    As per the given pie chart in question ,
    The corresponding angle of expenditure on food = 150°
    The corresponding angle of expenditure on house rent = 120°
    Change in expenditure = The corresponding angle of expenditure on food - The corresponding angle of expenditure on house rent = 150 - 120 = 30°

    Required percent =
    Change in expenditure
    		 × 100
    The corresponding angle of expenditure on house rent

    Correct Option: A

    As per the given pie chart in question ,
    The corresponding angle of expenditure on food = 150°
    The corresponding angle of expenditure on house rent = 120°
    Change in expenditure = The corresponding angle of expenditure on food - The corresponding angle of expenditure on house rent = 150 - 120 = 30°

    Required percent =
    Change in expenditure
    		 × 100
    The corresponding angle of expenditure on house rent

    Required percent =
    30
    		× 100 = 25%

Direction: The following pie-chart shows the percentage distribution of the expenditure incurred in publishing a book. Read the pie-chart and answer the questions.

  1. If for a certain quantity of books, the publisher has to pay $ 30600 as printing cost, then the amount of royalty cost to be paid for these books is :

    According to given pie chart in question ,
    Percentage of printing cost = 20%
    Percentage of Royalty cost = 15%
    Printing cost = $ 30600
    ∵ 20% ≡ $ 30600

    ∴ 1% ≡
    30600
    20

    ∴ Required paid amount =
    Printing cost
    		 × Percentage of Royalty cost
    Percentage of printing cost

    Correct Option: C

    According to given pie chart in question ,
    Percentage of printing cost = 20%
    Percentage of Royalty cost = 15%
    Printing cost = $ 30600
    ∵ 20% ≡ $ 30600

    ∴ 1% ≡
    30600
    20

    ∴ Required paid amount =
    Printing cost
    		 × Percentage of Royalty cost
    Percentage of printing cost

    ∴ Required paid amount =
    30600
    		× 15 = $ 22950
    20


  1. If 5500 copies are published and the transportation cost on them amount to $ 82500 then the selling price of the book so that the publisher can earn a profit of 25% is :

    As per the given pie chart in question ,
    Total number of published copies = 5500
    Transportation cost = 10%
    Transportation cost = $ 82500
    ∵ 10% ≡ $ 82500
    ∴ 100% ≡ $ 825000

    ∴ Cost for publishing 1 book =
    825000
    		= $ 150
    5500

    Correct Option: B

    As per the given pie chart in question ,
    Total number of published copies = 5500
    Transportation cost = 10%
    Transportation cost = $ 82500
    ∵ 10% ≡ $ 82500
    ∴ 100% ≡ $ 825000

    ∴ Cost for publishing 1 book =
    825000
    		= $ 150
    5500

    For a profit of 25% ,
    ∴ Required S.P. =
    150 × 125
    		 = $ 187.50
