    If 18 x 10 42 -22,

    Then, 50% of 2x - 25% of x = ?

    A 26 Correct Answer Incorrect Answer
    B 32 Correct Answer Incorrect Answer
    C 42 Correct Answer Incorrect Answer
    D 19.5 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    18 + 8 = 26 26 – 16 = 10 10 + 32 = 42 42 – 64 = - 22 Hence, x = 26 Hence, 50/100 × 2 × 26 - 25/100 × 26 = 26 – 13/2 = 19.5
