Two trains 150 meters and 180 meters long are running in the same direction with speeds of 102 km/hr, 66km/hr. In how much time will the first train cross the second  Options:
A) 37 sec
B) 22 sec
C) 27 sec
D) 35 sec
E) 33 sec
Explanation:   Relative speed of the trains = (102 - 66) km/hr = 36 km/hr   = (36Ã— 5/18) m/sec = 10 m/sec.   Time taken by the trains to cross each other   = Time taken to cover (150 + 180) m at 10 m /sec = (330/10)=
