Sorry abt the deletion. Had a change of mind! :-|
The answer is, indeed, 9. One train every half hour, including the train that is about to depart when a train reaches the other station.
Can someone please double check the answer provided? I think the answer is 5.
The train cannot meet more than 5 trains. There will be a total of 10 trains on the railway when it reaches the final destination.
hey i hv 2 answers..
1. only 1-bcoz it is not mentioned here whether the rail road is single lane or double lane.may b it could be single lane also depending upon the distance b/w two stations.
2. otherwise i think ans is 5.
I have two answers even..!!
1. Assume that the train started is the 1st one of the day, then that train will meet 6 trains; along with the train which is at the other station and ready to move at the 5th hour.
2. If that train is not the 1st train, then it may meet 10 trains along with the train on the other station.
