    According to given pie chart in question , Corresponding angle for expenditure on electricity = 72°
    Total angle for expenditure = 360°
    Total percent for expenditure = 100%
    ⇒ 360° ≡ 100%
    We know that ,

    ∴ Required percent =
    Total percent for expenditure
    		 × Corresponding angle for expenditure on electricity
    Total angle for expenditure

    Correct Option: D

    According to given pie chart in question , Corresponding angle for expenditure on electricity = 72°
    Total angle for expenditure = 360°
    Total percent for expenditure = 100%
    ⇒ 360° ≡ 100%
    We know that ,

    ∴ Required percent =
    Total percent for expenditure
    		 × Corresponding angle for expenditure on electricity
    Total angle for expenditure

    ∴ Required percent = 72° ≡
    100
    		× 72 = 20%
    360

Direction: Study the Pie chart carefully and answer the questions.

    As per the given pie chart in question ,
    Percent of non - members = 5%
    Number of members of non - members = 40
    ∴ 5% ≡ 40
    Percent of members of both the clubs = 75%

    Correct Option: D

    As per the given pie chart in question ,
    Percent of non - members = 5%
    Number of members of non - members = 40
    ∴ 5% ≡ 40
    Percent of members of both the clubs = 75%

    ∴ 75% ≡
    40
    		× 75 = 600
    5

    Hence , Number of members of both the clubs is 600

    From given above pie chart ,
    Percent of cricket club only = 5%
    Percent of football club only = 15%
    Required ratio = Percent of cricket club only : Percent of football club only

    Correct Option: A

    From given above pie chart ,
    Percent of cricket club only = 5%
    Percent of football club only = 15%
    Required ratio = Percent of cricket club only : Percent of football club only
    ∴ Required ratio = 5 : 15 = 1 : 3

  1. Number of students who are members of cricket club only :

    From given above pie chart ,
    Percent of Non–members = [ 100 – ( 75 + 15 + 5 ) ]% = 5%
    Number of Non–members = 40
    ⇒ 5% = 40 ........( 1 )
    Percent of cricket club only = 5%
    ⇒ Members of cricket club only = 40 { From ( 1 ) }

    Correct Option: B

    From given above pie chart ,
    Percent of Non–members = [ 100 – ( 75 + 15 + 5 ) ]% = 5%
    Number of Non–members = 40
    ⇒ 5% = 40 ........( 1 )
    Percent of cricket club only = 5%
    ⇒ Members of cricket club only = 40 { From ( 1 ) }
    Hence , Number of students who members of cricket club only are 40.
