    A 16 Correct Answer Incorrect Answer
    B 5 Correct Answer Incorrect Answer
    C 3 Correct Answer Incorrect Answer
    D 10 Correct Answer Incorrect Answer

    Solution

    According to the question,
    {(x + 6) × 8 × 5}/0.40 = {(x + 2) × 16 × 5}/0.60
    Or, 3x + 18 = 4x + 8
    Or, x = 10
    Hence, value of x is 10.
