Step-by-step explanation:

Train crosses the man standing on platform=10 seconds,

 

So speed of the train =225/10= 22.5 m/sec  

length of the train = 225 metres

Time taken by the train to cross a platform 405 metre long  

 

=length of train + platform / speed

 

=(225+405)20=630/22.5

Time taken by train = 28 seconds
