Two trains 120 meters and 150 meters long are running in the same direction with speeds of 92 km/hr, 56km/hr. In how much time will the first train cross the second Choose the most appropriate option
A) 37 sec  B) 22 sec  C) 27 sec  D) 35 sec  E) 36 sec
Explanation:   Relative speed of the trains = (92 - 56) km/hr = 36 km/hr   = (36× 5/18) m/sec = 10 m/sec.   Time taken by the trains to cross each other   = Time taken to cover (120 + 150) m at 10 m /sec = (270/10)=
