    On the basis of given pie chart in question ,
    Percentage expense on royalty = 15%
    Percent of total expenditure = 100%
    Corresponding angle for total expenditure = 360°
    ∵ 100% ≡ 360°

    ∴ Required angle =
    Corresponding angle for total expenditure
    × Percentage expense on royalty = 54°
    Percent of total expenditure

    Correct Option: C

    On the basis of given pie chart in question ,
    Percentage expense on royalty = 15%
    Percent of total expenditure = 100%
    Corresponding angle for total expenditure = 360°
    ∵ 100% ≡ 360°

    ∴ Required angle =
    Corresponding angle for total expenditure
    × Percentage expense on royalty = 54°
    Percent of total expenditure

    ∴ Required angle =
    360
    × 15 = 54°

    On the basis of given pie chart in question ,
    Corresponding angle for raw materials = 90°
    Percent of total expenditure = 100%
    Corresponding angle for total expenditure = 360°
    we know that , 360° ≡ 100%

    Correct Option: A

    On the basis of given pie chart in question ,
    Corresponding angle for raw materials = 90°
    Percent of total expenditure = 100%
    Corresponding angle for total expenditure = 360°
    we know that , 360° ≡ 100%

    ∴ Required percent = 90° ≡
    100
    × 90 = 25%
    360

    According to given pie chart in question ,
    Percent of royalty cost = 20%
    Percent of printing cost = 15%
    Change in cost = 20 - 15 = 5%

    Required percent = Change in cost × 100 %
    Percent of royalty cost

    Correct Option: C

    According to given pie chart in question ,
    Percent of royalty cost = 20%
    Percent of printing cost = 15%
    Change in cost = 20 - 15 = 5%

    Required percent = Change in cost × 100 %
    Percent of royalty cost

    Required percent = 20 - 15× 100 %
    20

    Required percent = 5× 100 % = 25%
    20


Direction: The following pie–chart shows the monthly expenditure of a family on various items. If the family spends $ 825 on clothing, answer the questions.

    On the basis of given pie chart in question ,
    Given that , Expenditure on clothes = Rs. 825.
    The corresponding angle of total expenditure = 360°
    The corresponding angle of expenditure on clothes = 36°
    ∵ 36° ≡ $ 825

    ∴ Total monthly income =
    Expenditure on clothes
    × The corresponding angle of total expenditure
    The corresponding angle of expenditure on clothes

    Correct Option: B

    On the basis of given pie chart in question ,
    Given that , Expenditure on clothes = Rs. 825.
    The corresponding angle of total expenditure = 360°
    The corresponding angle of expenditure on clothes = 36°
    ∵ 36° ≡ $ 825

    ∴ Total monthly income =
    Expenditure on clothes
    × The corresponding angle of total expenditure
    The corresponding angle of expenditure on clothes

    ∴ Total monthly income =
    825
    × 360 = & 8250
    36

    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
