    Explanation:

     Relative speed of te trains = (100 - 64) km/hour = 36 km/hour
     
                 = (36x5/18)m/sec = 10 m/sec
            
                  Time taken by the trains to cross each other =

                 Time taken to cover (150+ 130)m at 5 m/sec 
           
                 = (280/10) sec = 28 sec
