Question
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?
Answer: Option D
 - Relative speed = (120 + 80) km/hr
[200 x 5/18] m/sec = [500/9] m/sec.
Let the length of the other tain be x metres.
Then, x + 270 / 9 = 500/9
⇔ x + 270 = 500
⇔ x = 230.
