    We have , 10% ≡
    360
    		 × 10 = 36°
    100

    As per the given pie chart in question ,
    Percentage of printing charge = 35%
    Percentage of advertisement charge = 18%
    Difference of percentage charges on printing and advertisement = 35 – 18 = 17%
    As we know that , 100% ≡ 360°

    ∴ 1% =
    360°
    100

    Correct Option: B

    As per the given pie chart in question ,
    Percentage of printing charge = 35%
    Percentage of advertisement charge = 18%
    Difference of percentage charges on printing and advertisement = 35 – 18 = 17%

    ∴ 1% =
    360°
    100

    Now , we have 17% ≡
    360
    		× 17 = 61.2°
