            Let x be the total no. Of spectators 
2/7 of the spectators were in a covered place i.e 2/7x and 15000 were in a covered place.
     Therefore total no. Of spectators ,
                      x=2/7x + 15000
                      x-2/7x=15000
                       5x = 15000*7
                      x= 3000*7
                        x=21000.
