What if it was not a prokaryotic organism and a eukaryotic then how can we solve such problems .what is the method ?

One nucleosome has 147 bp of DNA. So just divide the total bp by 147 to get no of nucleosome

ecoli has 4.6*106 bps 
nucleosome has 200 bps
here 1 nucleosome = 200bp
         x nucleosome= 4.6*106 bps
      
      x =4.6*106 bps/200 = 2.3 * 104
