    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°
    100


  1. Royalty on the book is less than the printing cost by :

    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: Study the pie chart and answer the given questions. The total expenditure of a company for a particular month is Rs. 60000. The various heads of expenditure I to IV are indicated in a pie chart given below. These heads are :
I. Raw materials
II. Conveyance
III. Electricity
IV. Overhead expenses

  1. What percentage of total expenditure is on raw materials?

    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


  1. What is the amount spent on overhead expenses?

    According to given pie chart in question ,
    Corresponding angle for overhead expenses = 108°
    Total expenditure = $ 60000
    ⇒ 360° ≡ $ 60000

    ∴ Required amount =
    Total expenditure
    × Corresponding angle for overhead expenses
    Total angle for expenditure

    Correct Option: C

    According to given pie chart in question ,
    Corresponding angle for overhead expenses = 108°
    Total expenditure = $ 60000
    ⇒ 360° ≡ $ 60000

    ∴ Required amount =
    Total expenditure
    × Corresponding angle for overhead expenses
    Total angle for expenditure

    ∴ Required amount = 108° ≡
    60000
    × 108 = $ 18000
    360


  1. Total expenditure on conveyance is :

    As per the given pie chart in question ,
    Corresponding angle for conveyance = 90°
    Total expenditure = 360° ≡ $ 60000

    ∴ Total expenditure on conveyance = 90° ≡
    Total expenditure
    × Corresponding angle for conveyance
    360

    Correct Option: B

    As per the given pie chart in question ,
    Corresponding angle for conveyance = 90°
    Total expenditure = 360° ≡ $ 60000

    ∴ Total expenditure on conveyance = 90° ≡
    Total expenditure
    × Corresponding angle for conveyance
    360

    Total expenditure on conveyance =
    60000
    × 90 = $ 15000
    360
