Question

A large chess tournament starts with 1024 players. How many players will be remaining after 6 rounds

Answer 1

16

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)
