    ∵ 100% ≡ 360°

    ∴ 1% ≡
    360°
    100

    According to given pie chart in question ,
    Corresponding angle for clothing, transportation and entertainment = 18° + 14° + 13° = 45°
    ∵ 360° ≡ 100%

    ∴
    1° =
    100
    360

    Correct Option: D

    According to given pie chart in question ,
    Corresponding angle for clothing, transportation and entertainment = 18° + 14° + 13° = 45°
    ∵ 360° ≡ 100%

    ∴
    1° =
    100
    360

    ∴ 45° ≡
    100
    		× 45 =
    25
    		 = 12.5%

    On the basis of given pie chart in question ,
    Corresponding angle for rent = 54°
    Total income of Mr. Rao = $72000
    ∵ 360° ≡ $ 72000

    ∴
    1° =
    72000
    360


    Correct Option: C

    On the basis of given pie chart in question ,
    Corresponding angle for rent = 54°
    Total income of Mr. Rao = $72000
    ∵ 360° ≡ $ 72000

    ∴
    1° =
    72000
    360

    ∴ 54° ≡ $72000 × 54 = $ 10800

  1. The amount spent on food exceeds the total amount spent on education and clothing by










  1. View Hint View Answer Discuss in Forum

    According to given pie chart in question ,
    Corresponding central angle :-
    Food ⇒ 90°
    Education + Clothing ⇒ 27 + 18 = 45°
    Change in angle = 90° - 45° = 45°

    ∴ Required percent =
    Change in angle
    		× 100
    Corresponding central angle of ( Education + Clothing )


    Correct Option: E

    According to given pie chart in question ,
    Corresponding central angle :-
    Food ⇒ 90°
    Education + Clothing ⇒ 27 + 18 = 45°
    Change in angle = 90° - 45° = 45°

    ∴ Required percent =
    Change in angle
    		× 100
    Corresponding central angle of ( Education + Clothing )

    ∴ Required percent =
    45°
    		 × 100 = 100%
    45
