    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

    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

  1. The total money spent on clothes and miscellaneous is :

    On the basis of given pie chart in question ,
    The corresponding angle for expenditure on clothes = 30°
    The corresponding angle for expenditure on miscellaneous = 60°
    Since total amount of expenditure is not given.

    Correct Option: A

    On the basis of given pie chart in question ,
    The corresponding angle for expenditure on clothes = 30°
    The corresponding angle for expenditure on miscellaneous = 60°
    Since total amount of expenditure is not given.
    Hence , option A is correct answer .

  1. The percentage of money spent on food compared to house rent is

    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%
    120

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 :








  1. View Hint View Answer Discuss in Forum

    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


Direction: The Expenditure of a family in a month is represented by a Pie-chart. Read it carefully to answer the questions.

  1. If the total amount spent is $ 7,200, find the amount spent on food :








  1. View Hint View Answer Discuss in Forum

    On the basis of given pie chart in question , Corresponding angle for expense on food = 150°
    Total expenditure amount = $ 7200
    Corresponding angle for total expenditure = 360°
    ∵ 360° ≡ $ 7200

    ∴ Expenditure on food = $Total expenditure amount × Corresponding angle for expense on food
    Corresponding angle for total expenditure

    Correct Option: D

    On the basis of given pie chart in question , Corresponding angle for expense on food = 150°
    Total expenditure amount = $ 7200
    Corresponding angle for total expenditure = 360°
    ∵ 360° ≡ $ 7200

    ∴ Expenditure on food = $Total expenditure amount × Corresponding angle for expense on food
    Corresponding angle for total expenditure

    ∴ Expenditure on food = 150° ≡ $7200× 150 = $ 3000
    360
