    Subtracting 30 from 14 times a number gives a result

    which is 50 more than 9 times the number. What is the number?
    A 66 Correct Answer Incorrect Answer
    B 42 Correct Answer Incorrect Answer
    C 28 Correct Answer Incorrect Answer
    D 16 Correct Answer Incorrect Answer

    Solution

    Let the number be ‘x’
    Then, according to the question,
    (14x – 30) = 9x + 50
    Or, 14x – 9x = 50 + 30
    Or, 5x = 80
    So, x = (80/5) = 16
