Direction: The pie chart given here shows the breakup of the cost of construction of a house on various heads. Study the chart and answer the questions.

  1. Out of the total cost ($ 15,00,000) of construction how much amount of money was spent on labour and supervision combined together?

    Corresponding angle of labour and supervision combined
    = 90° + 54° = 144°
    ∵ 360° ≡ 1500000

    ∴ 144° ≡
    1500000
    × 144
    360

    = $ 600000

    Correct Option: C

    Corresponding angle of labour and supervision combined
    = 90° + 54° = 144°
    ∵ 360° ≡ 1500000

    ∴ 144° ≡
    1500000
    × 144
    360

    = $ 600000

    Corresponding angle on the expenditure on bricks, steel and cement
    = 54 + 54 + 72 = 180°
    ∵ 360° ≡ 100%

    ∴ 180° ≡
    100
    × 180 = 50%
    360

    Correct Option: A

    Corresponding angle on the expenditure on bricks, steel and cement
    = 54 + 54 + 72 = 180°
    ∵ 360° ≡ 100%

    ∴ 180° ≡
    100
    × 180 = 50%
    360


  1. If the total cost of construction of the house is $ 15,00,000, how much amount of money was spent on labour?









  1. View Hint View Answer Discuss in Forum

    Corresponding angle of labour = 90°

    Clearly, 90° =
    1500000 × 90
    360

    = $ 375000

    Correct Option: D

    Corresponding angle of labour = 90°

    Clearly, 90° =
    1500000 × 90
    360

    = $ 375000



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