Correct option (C) 10 : 26 am
Explanation:
First train from Pune to Mumbai takes 4hrs.
Second train from Mumbai to Pune takes 3.5hrs.
Speed of train from Pune to Mumbai is V1 = d/4
Speed of train from Mumbai to Pune is V2 = d/3.5
Distance traveled by first train till 9:30 is x = d/4 x 2 = d/2
Say now both trains meet after time from 9:30
Then both train meet at 9.30 + 56 min = 10 : 26 am
