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: Select.
A) 50 m
B) 72 m
C) 80 m
D) 82 m
E) 84 m
Let the length of each train be x metres.   Then, distance covered = 2x metres.   Relative speed = (46 - 36) km/hr   (10 x (5/18) ) m/s = 25/9 m/s   2x/36 = 25/9   2x=100   x=50   50 mNSWER:50 m
