    Let (17.28 / y) / (3.6 x 0.2) = 200
    Then,17.28 / y = 200 x 3.6 x 0.2
    ∴ y = 17.28 / (200 x 3.6 x 0.2)
    = 1728 / 200 x 36 x 2

    Correct Option: D

    Let (17.28 / y) / (3.6 x 0.2) = 200
    Then,17.28 / y = 200 x 3.6 x 0.2
    ∴ y = 17.28 / (200 x 3.6 x 0.2)
    = 1728 / 200 x 36 x 2
    = 0.12.

    Let 3420 / 19 = (y / 0.01) x 7
    Then , y = ( 3420 / 19) x (0.01 / 7)
    = 180 / 700

    Correct Option: D

    Let 3420 / 19 = (y / 0.01) x 7
    Then , y = ( 3420 / 19) x (0.01 / 7)
    = 180 / 700
    = 9/35

    Given expression = 8.32 x 0.999
    = 8.32 x (1- 0.001)
    = 8.32 - 8.32 x 0.001

    Correct Option: C

    Given expression = 8.32 x 0.999
    = 8.32 x (1-0.001)
    = 8.32 - 8.32 x 0.001
    =8.32 - .00832
    = 8.31168.
