    As per the given pie chart in question ,
    Corresponding central angle for miscellaneous expenditure = 108°
    ∵ 360° ≡ 100%

    ∴ 1° ≡
    100
    %
    360

    Correct Option: D

    As per the given pie chart in question ,
    Corresponding central angle for miscellaneous expenditure = 108°
    ∵ 360° ≡ 100%

    ∴ 1° ≡
    100
    %
    360

    ∴ 108° ≡
    108 × 100
    = 30%
    360


Direction: The pie graph indicates the break-up of the cost of construction of a house. Assuming that the total cost of construction is $ 6,00,000, answer the following questions.

  1. The percentage of the total cost of construction spent on cement, steel and supervision is :

    From the given pie chart in question ,
    Corresponding angle for cement, steel and supervision = 72° + 54° + 54° = 180°

    ∴ Required percent =
    Corresponding angle for cement, steel and supervision
    × 100
    360°

    Correct Option: A

    From the given pie chart in question ,
    Corresponding angle for cement, steel and supervision = 72° + 54° + 54° = 180°

    ∴ Required percent =
    Corresponding angle for cement, steel and supervision
    × 100
    360°

    ∴ Required percent =
    180 °
    × 100 = 50%
    360°


  1. The amount spent on labour exceeds the amount spent on steel by :

    On the basis of given pie chart in question ,
    Corresponding central angles :
    Labour ⇒ 90°
    Steel ⇒ 54°
    ∴ Required excess amount = Corresponding central angle of Labour - Corresponding central angle of Steel

    Correct Option: A

    On the basis of given pie chart in question ,
    Corresponding central angles :
    Labour ⇒ 90°
    Steel ⇒ 54°
    ∴ Required excess amount = Corresponding central angle of Labour - Corresponding central angle of Steel
    ∴ Required excess amount = 90° – 54° = 36° i.e. 10% of total cost.


  1. The amount spent on labour exceeds the amount spent on supervision by :

    From the given pie chart in question ,
    Corresponding central angles :
    Labour ⇒ 90°
    Supervision ⇒ 54°
    Difference = Corresponding central angle of Labour - Corresponding central angle of Supervision
    Difference = 90° – 54° = 36°

    Correct Option: C

    From the given pie chart in question ,
    Corresponding central angles :
    Labour ⇒ 90°
    Supervision ⇒ 54°
    Difference = Corresponding central angle of Labour - Corresponding central angle of Supervision
    Difference = 90° – 54° = 36°

    ∴ Required excess amount = $ 36 × 600000 = $ 60000
    360


  1. The amount spent on timber is :

    According to given pie chart in question ,
    Corresponding central angle for the cost on timber = 36°
    Total cost of construction = $ 6,00,000
    ∵ 360° ≡ $ 600000


    1° =
    600000
    360

    Correct Option: A

    According to given pie chart in question ,
    Corresponding central angle for the cost on timber = 36°
    Total cost of construction = $ 6,00,000
    ∵ 360° ≡ $ 600000


    1° =
    600000
    360

    ∴ 36° ≡ $600000 × 36 = $ 60000
    360
