A train takes 18 seconds to cross a platform while running at 25 km/hr and it takes 12 seconds to pass a men walking at 5 km/hr in the opposite direction. Length of train in how much more than length of the platform (in m)
50
75
100
125
150
Let the length of the train = L And, the length of the platform = P So, 25x 5/18 =(L+P)/18
L+P = 125 And, 30 x 5/18= L/12 L = 100 P = 25 Required difference = 100 – 25 = 75 So, option (b) is the correct answer.
