  • Question
  • Sum of the ages of Rajesh, Suresh, Mahesh and Dinesh is 76 years. 7 years hence, their age ratio is 7:6:5:8. Find Mahesh?s present age ?


  • Options
  • A. 17 years
  • B. 13 years
  • C. 14 years
  • D. 16 years

  • Correct Answer
  • 13 years 

    Explanation

    Given R + S + M + D = 76

    => R+7 : S+7 : M+7 : D+7 = 7:6:5:8

    => Let the ratio = x

    => M+7 = 5x

    => M = 5x-7

    => R = 7x-7

    => S = 6x-7

    => D = 8x-7

    => R + S + M + D = 76

    => 7x-7 + 6x-7 + 5x-7 + 8x-7 = 76

    => 26x - 28 = 76

    => 26x = 104

    => x = 4

    => Mahesh's present age = 5x-7 = 20 - 7 = 13 years.
