  • Question
  • A train P start from Mokama at 5:00 pm reached Hazipur at 6:00 pm. An another train Q starts from Hazipur at 5:00 pm and reaches Mokama at 6:30 pm. At what time, two trains will cross each other?


  • Options
  • A. 5 : 36 pm
  • B. 4 : 36 pm
  • C. 6 : pm
  • D. 7 : 00 pm

  • Correct Answer
  • 5 : 36 pm 

    Explanation

    Let the distance between Mokama and Hazipur be D km
    Time taken by train P to cover D km = 1 h
    Time taken by Q to cover D km = 3/2 h
    ? Speed of train P = D km/h
    Speed of train Q = 2D/3 km/h .
    Let they cross each other T h after 5 : 00 pm.
    Then, DT + 2DT/ 3 = D
    ? T + 2T/3 = 1
    ? T(1 + 2/3) = 1
    ? T = 3/5h = (3/5) x 60 = 3 x 12 = 36 min.

    Hence, the two trains meet 36 min after 5 : 00 pm.
    ? Meeting time = 5:36 pm
