    4.
    A 6 Correct Answer Incorrect Answer
    B 4 Correct Answer Incorrect Answer
    C 7 Correct Answer Incorrect Answer
    D None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Check last 3 digits: 1x8

    Try x = 2 ⇒ 128 ÷ 8 = 16 (divisible)

    Try x = 5 ⇒ 158 ÷ 8 = 19.75 (not divisible)

    Try x = 6 ⇒ 168 ÷ 8 = 21 (divisible)

    So x = 2 or 6

    x > 4,

    x = 6
