  • Question
  • The ages of A and B are in the ratio of 11 : 13 respectively. After 7 years the ratio of their ages will be 20 : 23. What is the difference in years between their ages?


  • Options
  • A. 4 years
  • B. 5 years
  • C. 6 years
  • D. 7 years

  • Correct Answer
  • 6 years 

    Explanation

    Let the present ages of A and B are 11x and 13x years respectively; then
    According to question,
    After 7 years the ratio of their ages will be 20 : 23.
    (11x + 7 ) / (13x + 7) = 20/23
    ? (11x + 7 ) 23 = 20 (13x + 7)
    ? 253x + 161 = 260x + 140
    ? 7x = 21
    ? x = 3
    Hence, difference of their ages = 13x - 11x = 2x = 2 x 3 = 6 years
