A train starts from Delhi at 6:00 am and reaches Ambala cantt. at 10am. The other train starts from Ambala cantt. at 8am and reached Delhi at 11:30 am, If the distance between Delhi and Ambala cantt is 200 km, then at what time did the two trains meet each other?

A.

8:46 am

B.

8:30 am

C.

8:56 am

D.

8:50 am

• Let t be the start time
  
  A starts at t, while B starts at (t-2)
  
  total distance covered is 200 km
  
  as they are travelling in opposite direction,
  
  relative dist covered
  
  i,e 200=((200/4)*t )+((400/7)*(t-2))
  
  t=176min
  
  i.e 2hrs 56min from start (6 am)
  
  therefore they meet at 8.56am.
