      that the resulting numbers are in the ratio of 7:5?
      A 12 Correct Answer Incorrect Answer
      B 6 Correct Answer Incorrect Answer
      C 10 Correct Answer Incorrect Answer
      D 8 Correct Answer Incorrect Answer

      Solution

      Let the required number be 'y'.

      ATQ, (36 - y) :(28 - y) = 7:5

      Or, 5 X (36 - y) = 7 X (28 - y)

      Or, 180 - 5y = 196 - 7y

      Or, 2y = 16

      So, 'y' = 8
