    Solution

    ATQ, To check divisibility by 4 and 8, we focus on the last two digits: Divisible by 4: The last two digits should be divisible by 4. Divisible by 8: The last two digits should also be divisible by 8. Check each number: 4382: Last two digits = 82 82 ÷ 4 = 20.5 (Not divisible by 4 or 8) (wrong) 3824: Last two digits = 24 24 ÷ 4 = 6 (Divisible by 4) 24 ÷ 8 = 3 (Divisible by 8) (correct) 8342: Last two digits = 42 42 ÷ 4 = 10.5 (Not divisible by 4 or 8) (wrong) 3842: Last two digits = 42 42 ÷ 4 = 10.5 (Not divisible by 4 or 8) (wrong)
