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.
A) 48 B) 49 C) 50 D) 51 E) 52
Let the length of each train be x metres.   Then, distance covered = 2x metres.   Relative speed = (46 - 36) km/hr   = 10x5/18 m/sec   = 25/9 m/sec   = 2x/36 =25/9   2x =100   X=50   answer :50
