infosys - a train starts from station 1 and travels towards station 4 it reaches station 2 at 23 of its journey and station 3 at 34 of its journey the time taken to travel between station 2 and station 3 is 20 minutes and it reaches station 3 at 1015pm if it l - skillgun

Here the train reach station 2 and station 3 at 2/3 and 3/4 of its journey respectively.Distance between station 2 and 3 = 3/4 - 2/3 = 1/12
Time taken to cover 1/12 of total distance = 20 mins
Then, Time taken to complete whole journey = 20 x 12 = 240 mins (without loss of time)
Time taken to reach station 3(to covers 3/4) = 240 x 3/4 = 180 mins
It covers 3/4 journey at 10.15pm then it would have started at 10.15 pm - 180 mins = 7.15 pm
And it reach station 4 at 7.15 pm + 240 mins = 11.15pm (without loss of time)
Given that, it loses 10 mins on each station.so it starts at 7.15 pm at station1, reaches station 2 and takes 10 mins, reaches station3 and takes 10 mins and then finally reach station 4.
Thus, it reach station4 at 11.15 pm + 20 minutes = 11.35 pm.
