    A 10,508 Correct Answer Incorrect Answer
    B 10,000 Correct Answer Incorrect Answer

    D 10,024 Correct Answer Incorrect Answer

    Solution

    ATQ,

    LCM of 14, 21, 35 and 42 = 420

    Least 5-digit number = 10000

    So, 10000 ÷ 420 = 23.80

    Therefore, we should multiply 24 and 420 to get the required 5-digit number

    So, required number = 10,080
