    As we know that , 100% ≡ 360°

    ∴ 1% ≡
    360
    100

    ∴ 25% ≡
    360
    		× 25 = 90°
    100

    Correct Option: D

    As we know that , 100% ≡ 360°

    ∴ 1% ≡
    360
    100

    ∴ 25% ≡
    360
    		× 25 = 90°
    100

    Angle of Art and Craft = 90°
    From given pie chart in question it is clear that Art and Craft uses 25% of the funds.

    As per the given in pie chart ,
    The corresponding angle of expenditure on library = 60°
    Total expenditure = 360°

    ∴ Required percent =
    The corresponding angle of expenditure on library
    		 × 100
    Total expenditure

    ∴ Required percent =
    60
    		× 100
    360

    Correct Option: D

    As per the given in pie chart ,
    The corresponding angle of expenditure on library = 60°
    Total expenditure = 360°

    ∴ Required percent =
    The corresponding angle of expenditure on library
    		 × 100
    Total expenditure

    ∴ Required percent =
    60
    		× 100
    360

    Required percent =
    50
    		= 16.67%
