Answer:

16

Step-by-step explanation:

After reach round the number of players will be reduced by a half.

After 1 round it will be 1024 * 11/2 = 512, after  2 rounds it will be 1024 * (1/2)^2 = 256 etc..

Thus, after 6 rounds  the remaining players will be 1024* (1/2)^6

=  16  (answer)

1% = 12.5
100% = 12.5 x 100 = 1250
