Question

    If a number is decreased by 30 and divided by 12, the result is 20. What would be the result if 200 is subtracted from that number and then it is divided by 14?

    A 13 Correct Answer Incorrect Answer
    B 15 Correct Answer Incorrect Answer
    C 5 Correct Answer Incorrect Answer
    D 10 Correct Answer Incorrect Answer

    Solution

    Let the number be x ∴ (x-30)/12 = 20 ⇒ x - 30 = 20 × 12 ⇒ x = 270 Result = (270 - 200)/14 = 5
