Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is:  Choose the correct choice from the following options.
A) 50 B) 55 C) 100 D) 25 E) 52
Let the length of each train be x metres.   Then, distance covered = 2x metres.   Relative speed = (46 - 36) km/hr   =10 x5/18	m/sec   =25/9m/sec   2 x/36=25/9   2x = 100   x = 50.   50nswer 50
