      Question

      When 42 is taken away from 12 times a number, the result

      is 66 more than 5 times the number. What is the approximate number?
      A 66 Correct Answer Incorrect Answer
      B 42 Correct Answer Incorrect Answer
      C 28 Correct Answer Incorrect Answer
      D 15 Correct Answer Incorrect Answer

      Solution

      Let the number be β€˜x’
      Then, according to the question,
      (12x – 42) = 5x + 66
      Or, 12x – 5x = 66 + 42
      Or, 7x = 108
      So, x = (108/7) = 15.43 or approx 15
