Train P travelling at 55 km/hr crosses another train Q, having three fourth of its length and travelling in opposite direction at 35 km/hr in 14 seconds. Train P passed a railway platform in 36 seconds. Find the length of platform.
Let the length of the first train is x metre Length of second train = 3x/4 Therefore, (55 + 35) x 5/18 = {x + (3x/4)}/14 ⇒ 90 x 5/18 = (7x/4)/14 ⇒ x = 200 m Therefore, let the length of the platform be y metre ⇒ 55 x 5/18 = (200 + y)/36 ⇒ 550 = 200 + y ⇒ y = 550 – 200 = 350 m
