      Solution

      Let the time period of A, B and C be 4a, 3a and 6a respectively.
      Profit sharing ratio of A, B and C = 15X × 4a : (3X + 26) × 3a : (1000 – 6X) × 6a
      ATQ,
      (15X Ă— 4a)/((3X + 26) Ă— 3a) = 5/4
      => (60X)/(9X + 78) = 5/4

      4 Ă— 60X = 5(9X + 78)
      240X = 45X + 390
      195X = 390
      X = 2
      Required value = 20 Ă— 2 = 40
