    Question

    The LCM of two numbers is 5400 while their HCF is 90.

    If one of the numbers is 900, then the other number is:
    A 600 Correct Answer Incorrect Answer
    B 900 Correct Answer Incorrect Answer
    C 1200 Correct Answer Incorrect Answer
    D 540 Correct Answer Incorrect Answer

    Solution

    Given:
    - LCM of two numbers = 5400
    - HCF of two numbers = 90
    - One number = 900

    Since,
    HCF of two numbers × LCM of two numbers = First number × Second number
    Second number = (90 × 5400)/900 = 486000/900 = 540
    So, the other number is 540.
