  • Question
  • The ratio of present ages of two brothers is 1 : 2 and 5 years ago the ratio was 1: 3. What will be the ratio of their ages after 5 years?


  • Options
  • A. 1 : 4
  • B. 2 : 3
  • C. 3 : 5
  • D. 5 : 6

  • Correct Answer
  • 3 : 5 

    Explanation

    Let us assume their present ages be x and 2x years; then
    5 years ago ages of the brothers was x - 5 and 2x - 5 years.
    According to question, 5 years ago the ratio was 1: 3
    ( x - 5)/(2x - 5) = 1/3
    ? 3x-15 = 2x -5
    ? x = 10
    Hence, their present ages 10 years and 20 years.
    Ages after 5 years will be 10 +5 and 20 + 5 Years
    Required ratio = 10+5/20 + 5 = 15/25 = 3/5 = 3 : 5
