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?	Options:  A) 230 m  B) 240 m  C) 260 m  D) 320 m  E) None of these
Explanation:   Relative speed = (120 + 80) km/hr   =(200 x5/18)m/sec   =(500/9)m/sec   Let the length of the other train be x metres.   Then,	x + 270 / 9 =500/9   x + 270 = 500   x = 230.   230 mNSWER IS 230 m
