    Question

    In the number 862x4, if it is divisible by 56 and x > 5,

    then what is the value of x?
    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 divisibility by 8 using last 3 digits: 2x4

    Try x = 0 ⇒ 204 ÷ 8 = 25.5 (not divisible)

    Try x = 3 ⇒ 234 ÷ 8 = 29.25 (not divisible)

    Try x = 6 ⇒ 264 ÷ 8 = 33 (divisible)

    Try x = 8 ⇒ 284 ÷ 8 = 35.5 (not divisible)

    So only x = 6 makes it divisible

    Since x > 5,

    x = 6
