  • Question
  • A is twice as fast as B and B is thrice as fast as C. The journey covered by C in 56 min will be covered by A in?


  • Options
  • A. 51/3 min
  • B. 21/3 min
  • C. 71/3 min
  • D. 91/3 min

  • Correct Answer
  • 91/3 min 

    Explanation

    Let time taken by A = Y
    Let speed of C = x
    Then, speed of B = 3x
    ? speed of A = 6x
    Now, ratio of speeds of A and C = Ratio of time taken by C and A
    6x : x = 56 : y
    ? 6x/x = 56/y
    ? y = 56/6 = 92/6
    = 91/3 min
