    x=60

    Step-by-step explanation:

    Given that,

    HCF of 140 and x=20,

    LCM of 140 and x = 420.

    Solution:

    It is known that the product of two numbers is equal to the product of their HCF and LCM, i-e:

    140*x = HCF*LCM

    Putting in the values provided,

    140*x=20*420

    140*x=8400

    x=8400/140

    x=60

    Hence the variable x is 60.
