  • Question
  • A boy on being asked 13/14 of a certain fraction had made the mistake of dividing the fraction by 14/13 and so got an answer that exceeded the correct answer by 3/65. The correct fraction is?


  • Options
  • A. 14/45
  • B. 12/65
  • C. 13/45
  • D. 2/7

  • Correct Answer
  • 13/45 

    Explanation

    Let the fraction be N.
    Then, N / (13/14) - (13/14) x N = 3/65
    ? 14N/13 - 13N/14 = 3/65
    ? (196N - 169N)/182 = 3/65
    ? 27N/182 = 3/65
    ? N = (3 x 182) / (27 x 65) = 14/45
    So, correct answer will be (13/14) x (14/45) = 13/45
