    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

    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

    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

    According to given graph and pie chart in question ,
    Percent of Engineering colleges in 80’s = 15%
    Number of colleges in 80’s = 20000
    Percent of Engineering colleges in 90’s = 40%
    Number of colleges in 90’s = 40000

    Number of Engineering colleges in 80’s =
    20000 × 15
    		 = 3000
    100

    Correct Option: A

    According to given graph and pie chart in question ,
    Percent of Engineering colleges in 80’s = 15%
    Number of colleges in 80’s = 20000
    Percent of Engineering colleges in 90’s = 40%
    Number of colleges in 90’s = 40000

    Number of Engineering colleges in 80’s =
    20000 × 15
    		 = 3000
    100

    Number of Engineering colleges in 90°s =
    40000 × 40
    		 = 16000
    100

    Required difference = 16000 – 3000 = 13000
