    A 52 Correct Answer Incorrect Answer
    B 63 Correct Answer Incorrect Answer
    C 45 Correct Answer Incorrect Answer
    D 36 Correct Answer Incorrect Answer

    Solution

    HCF = 7, LCM = 495, a = 55 & b = ? So as we know that a × b = HCF × LCM or 55 × b = 7 × 495 or b = 7 × 495/55 = 3465/55 = 63.
