There was a question of train. 2 trains crossing each other in 23 seconds. A man standing on the platform.. Find the ratio of speeds of 2 trains.i cannot completely recall that question

• Let the speeds of the two trains be x m/sec and y m/sec respectively.
  
  Then, length of the first train = 27x metres,
  
  and length of the second train = 17y metres.
  
  27x + 17y / x+ y = 23
  
  27x + 17y = 23x + 23y
  
  4x = 6y
  
  x/y = 3/2

• Let the speeds of the two trains be x m/sec and y m/sec respectively.
  Then, length of the first train = 27x m,
  and length of the second train = 17y m
  
  (27x + 17y) / (x+y) = 23
  27x + 17y = 23x + 23y
  4x = 6y
  x/y=6/4=3/2
