    ∵ 360° ≡ 810

    ∴ 1° ≡
    810
    		=
    9

    3604

    ∴ 60° ≡
    9
    		× 60 = 135

    Sum of corresponding angles of Maths and Chemistry
    = 90 + 70 = 160°
    Sum of corresponding angles of Physics and Social Science
    = 85 + 55 = 140°
    Difference = 20°
    ∵ 360° ≡ 810

    ∴ 20° ≡
    810
    		× 20 = 45
    360

    Correct Option: D

    Sum of corresponding angles of Maths and Chemistry
    = 90 + 70 = 160°
    Sum of corresponding angles of Physics and Social Science
    = 85 + 55 = 140°
    Difference = 20°
    ∵ 360° ≡ 810

    ∴ 20° ≡

    Difference of corresponding angles :
    Physics and Chemistry = 85 – 70 = 15°
    Chemistry and social science = 70 – 55 = 15°

    Correct Option: A

    Difference of corresponding angles :
    Physics and Chemistry = 85 – 70 = 15°
    Chemistry and social science = 70 – 55 = 15°

    Difference of respective angles = 144° – 43.2° = 100.8°
    ∴ Required difference

    =
    96000
    		× 100.8° = $ 26880
    360°

    Correct Option: D

    Difference of respective angles = 144° – 43.2° = 100.8°
    ∴ Required difference

    =
    96000
    		× 100.8° = $ 26880

    ∵ 360° ≡ $ 96000

    ∴ 115.2° ≡
    96000
    		× 115.2
    360°

    = $ 30720

    Correct Option: A

    ∵ 360° ≡ $ 96000

    ∴ 115.2° ≡
    96000
    		× 115.2
    360°

    = $ 30720
