  • Question
  • The ratio between the present ages of A and B is 5 : 3 respectively. The ratio between A's age 4 years ago and B's age 4 years hence is 1 : 1. The ratio between A's age 4 years hence and B's age 4 year ago is:


  • Options
  • A. 4 : 1
  • B. 3 : 1
  • C. 2 : 1
  • D. 1 : 3

  • Correct Answer
  • 3 : 1 

    Explanation

    Let the present ages of A and B are 5x and 3x years respectively. Then
    A's age 4 years ago = 5x - 4
    B's age 4 years hence = 3x + 4
    According to question,
    The ratio between A's age 4 years ago and B's age 4 years hence is 1 : 1
    (5x - 4)/(3x + 4) = 1 : 1 = 1
    ? 5x - 4 = 3x + 4
    ? 2x = 8
    ? x = 4
    present ages of A and B are 20 and 12 years.
    The ratio between A's age 4 years hence and B's age 4 year ago is:
    Hence, required ratio = (20 + 4) : (12 - 4) = 24 : 8 = 3: 1
