    On the basis of given pie chart in question ,
    The corresponding angle of total smoking person = 360°
    The corresponding angle of without smoking people = 18°

    Correct Option: B

    On the basis of given pie chart in question ,
    The corresponding angle of total smoking person = 360°
    The corresponding angle of without smoking people = 18°

    Percentage of people without smoking habits =
    18 × 100
    		 = 5 %
    360

  1. The number of Cigarette smoking people is greater than the number of Pipe smoking people by :

    As per the given pie chart in question ,
    Difference between corresponding angles for cigarette and pipe users = 180° – 36° = 144°
    ∵ 360° ≡ 119060

    ∴ 1deg; =
    119060
    360

    Correct Option: B

    As per the given pie chart in question ,
    Difference between corresponding angles for cigarette and pipe users = 180° – 36° = 144°
    ∵ 360° ≡ 119060

    ∴ 1deg; =
    119060
    360

    ∴ 144° ≡
    119060
    		× 144 = 47624
    360

  1. The number of people preferring Bidi is :

    As per given pie chart in question ,
    Number of smoking people of tabacco = 119060
    The corresponding angle for Bidi = 90°
    We know that , 360° ≡ 119060

    ∴ 1deg; =
    119060
    360

    Correct Option: B

    As per given pie chart in question ,
    Number of smoking people of tabacco = 119060
    The corresponding angle for Bidi = 90°
    We know that , 360° ≡ 119060

    ∴ 1deg; =
    119060
    360

    ∴ 90° ≡
    119060
    		× 90 = 29765
    360

  1. The number of people smoking Cigarettes is :

    According to given pie chart in question ,
    Number of smoking people of tabacco = 119060
    The corresponding angle for Cigarettes = 180°
    ∵ 360° ≡ 119060

    ∴ 1deg; ≡
    119060
    360

    ∴ 1° ≡
    119060
    360

    Correct Option: C

    According to given pie chart in question ,
    Number of smoking people of tabacco = 119060
    The corresponding angle for Cigarettes = 180°
    ∵ 360° ≡ 119060

    ∴ 1deg; ≡
    119060
    360

    ∴ 1° ≡
    119060
    360

    ∴ 180° ≡
    119060 × 180
    		 = 59530
    360

  1. Let P be the percentage of people using Cigarettes, Pipe and Bidi as their smoking means and Q be the percentage of people using other means as their smoking habits. Then P is more than Q by :

    As per the given pie chart in question ,
    Corresponding angle for cigarette, pipe and bidi users = 180° + 36° + 90° = 306°
    Corresponding angle for other product consumers = 36°
    Difference = Corresponding angle for cigarette, pipe and bidi users - Corresponding angle for other product consumers = 306 – 36 = 270°
    As we know that , 360° ≡ 100%

    Correct Option: D

    As per the given pie chart in question ,
    Corresponding angle for cigarette, pipe and bidi users = 180° + 36° + 90° = 306°
    Corresponding angle for other product consumers = 36°
    Difference = Corresponding angle for cigarette, pipe and bidi users - Corresponding angle for other product consumers = 306 – 36 = 270°
    As we know that , 360° ≡ 100%

    ∴ 270° ≡
    100
    		× 270 = 75%
    360
