Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively and they cross each other in 23 seconds. The ratio of their speeds is ?
Let the speeds of the two trains be x m/sec and y m/sec respectively.
Then, length of the first train = 27x metres,
Length of the second train = 17y metres.
27x + 17y /x+y = 23
27x +17y = 23x = 23y
4x = 6y
x/y = 6/4 = 3/2
Hence, otpin 2 is the correct answer.
