  • Question
  • A train Meerut at 6 a.m. and reaches Delhi at 10 a.m. another train leaves Delhi at 8 a.m. and reaches Meerut at 11:30 a.m. at what time do trains cross one another?


  • Options
  • A. 9.26 a.m.
  • B. 9 a.m.
  • C. 8:36 a.m.
  • D. 8:56 a.m.

  • Correct Answer
  • 8:56 a.m. 

    Explanation

    Let the distance between Meerut and Delhi be y km.
    Average speed of the train leaving Meerut = y/4 km/hr.
    Average speed of the train leaving Delhi = 2y/7 km/hr.

    suppose they meet x hrs. after 6 a.m
    then, xy/4 + 2y (x-2)/7 = y
    ? x/4 + 2x-4/7 = 1
    ? 15x = 44

    ? x = 44/15 = 2 hrs. 56 min
    So, the train meet at 8:56 a.m
