      The ratio of the times taken by Aman, Bharat, and Charan

      to complete a task is 3:5:7 respectively. Dev takes 4 minutes more than Aman. If the difference in time between Charan and Aman is 48 minutes, what is the ratio of Bharat’s time to Dev’s time?
      A 4:5 Correct Answer Incorrect Answer
      B 5:4 Correct Answer Incorrect Answer
      C 2:3 Correct Answer Incorrect Answer
      D 3:2 Correct Answer Incorrect Answer

      Solution

      Let the times be 3x, 5x, and 7x respectively. 
      Dev = 3x + 4
      ATQ, 
      7x - 3x = 48 
      Or, 4x = 48 
      Or, x = 12

      Bharat = 5 × 12 = 60 
      Dev = 36 + 4 = 40

      Required ratio = 60:40 = 3:2
