    The sum of HCF and LCM of two numbers is 450. If the LCM

    is 14 times the HCF, and one number is 42, what is the second number?
    A 100 Correct Answer Incorrect Answer
    B 260 Correct Answer Incorrect Answer
    C 300 Correct Answer Incorrect Answer
    D 350 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let HCF = x

    LCM = 14x

    x + 14x = 450

    тЗТ 15x = 450

    тЗТ x = 30

    Now,

    42 ├Ч y = 30 ├Ч 14 ├Ч 30

    тЗТ 42y = 12600

    тЗТ y = 12600 ├╖ 42 = 300
