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 ?

A. 40 meter

B. 45 meter

C. 50 meter

D. 55 meter

Correct Answer : C.


Let the length of each train is x meter
Distance will be x+x = 2x
Relative Speed = 46-36 = 10 km/hr
= 10*(5/18) = 25/9 m/sec
Distance = Speed*Time
2x=259×362x=100⇒x=50
So length of both the trains are 50 meters
