    From the given pie chart in question ,
    Corresponding angle for expenses on education = 36°
    Corresponding angle for expenses on rent = 81°
    Difference between the respective angles for rent and education = 81 – 36 = 45°

    Correct Option: D

    From the given pie chart in question ,
    Corresponding angle for expenses on education = 36°
    Corresponding angle for expenses on rent = 81°
    Difference between the respective angles for rent and education = 81 – 36 = 45°

    ∴ Required answer = $ 45 × 16000 = $ 2000
    360

  1. The amount he spends on education is:

    From the given pie chart in question ,
    Corresponding angle for expenses on education = 36°
    ∵ 360° ≡ $ 16000

    ∴
    1° =
    16000
    360

    Correct Option: B

    From the given pie chart in question ,
    Corresponding angle for expenses on education = 36°
    ∵ 360° ≡ $ 16000

    ∴
    1° =
    16000
    360

    ∴ 36° ≡
    16000 × 36
    		= $ 1600
    360

    According to given pie chart in question ,
    Corresponding angle for food expenditure = 135°
    Corresponding angle for rent expenditure = 81°
    Required ratio = Corresponding angle for food expenditure : Corresponding angle for rent expenditure

    Correct Option: A

    According to given pie chart in question ,
    Corresponding angle for food expenditure = 135°
    Corresponding angle for rent expenditure = 81°
    Required ratio = Required ratio = Corresponding angle for food expenditure : Corresponding angle for rent expenditure
    Required ratio = 135° : 81° = 5 : 3

    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
