const N = 100;

var a: array [1..N] of real;  

       median: real;

       sum: real;

       count_more, i: integer;

begin

       randomize;

       for i:= 1 to N do a[i]:= random(1, 1000);

       sum:= 0;

       for i:= 1 to N do sum:= sum + a[i];

       median:= sum / N;

       count_more:= 0;

       for i:= 1 to N do begin

               if a[i] > median then inc(count_more)  

               else a[i]:= a[i] * 1.1;

       end;

       write(count_more);
