  • Question
  • Ten years ago, Karan was thrice as old as Shiva was but 10 years hence, he will be only twice as old. Find Shiva?s present age ?


  • Options
  • A. 70 years
  • B. 30 years
  • C. 60 years
  • D. 40 years

  • Correct Answer
  • 30 years 

    Explanation

    Let Karan?s present age be x years and Shiva?s present age be y years.
    Then, according to the first condition,
    x - 10 = 3(y - 10) or x - 3y = - 20 ..(1)
    Now, Karan?s age after 10 years = (x + 10) years
    Shiva?s age after 10 years = (y + 10)
    (x + 10) = 2 (y + 10) or x - 2y = 10 ..(2)
    Solving (1) and (2), we get x = 70 and y = 30
    Karan?s age = 70 years and Shiva?s age = 30 years.
