    No. of teams in upper half = \[\frac{N+1}{2}=\frac{21+1}{2}=11\] teams
    No of team in lower half = \[\frac{N-1}{2}=\frac{21-1}{2}=11\]teams
    Total No. of byes \[=3221=11\] byes
    No. of byes in upper half = \[\frac{NB-1}{2}=\frac{11-1}{2}=5\]byes
    No. of byes in lower half = \[\frac{NB+1}{2}=\frac{11+1}{2}=6\]byes
    Total round = 5

    No. of byes in I quarter = \[\frac{NB-1}{2}=\frac{5-1}{2}=2\]byes
    No. of byes in II quarter = \[\frac{NB+1}{2}=\frac{5+1}{2}=3\]byes
    No. of byes in III quarter = \[\frac{NB}{2}=\frac{6}{2}=3\]
