    A.

    128

    B.

    150

    C.

    182

    D.

    112

    Correct option is A

    Given:

    LCM of two numbers = 1920

    HCF of two numbers = 16

    One number = 240

    Formula Used:

    LCM × HCF = Product of the two numbers

    Solution:

    1920 × 16 = 240 × x

    192 × 2 = 3 × x

    64 × 2 = x

    x = 128
