A 270 metres long train running at the speed of 120 kmph crosses another train running in opposite direction at the speed of 80 kmph in 9 seconds. What is the length of the other train? Pick one:
A) 253m	B) 239m	C) 236m	D) 240m	E) 230m
Relative speed = (120 + 80) km/hr   200 x5/18= 500/9 m/sec   Let the length of the other train be x metres.   Then,x + 270/9	=500/9   x + 270 = 500   x = 230m   Answer 230m
