A 240 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) 230 m	B) 240 m	C) 260 m	D) 320 m	E) 330 m
Relative speed = (120 + 80) km/hr   =	(200 x(5/18))m/sec   =	(500/9)m/sec.   Let the length of the other train be x metres.   Then,	(x + 240)/9 = 500/9   x + 240 = 500   x = 260.   260 m
