after every minute he travel 20 mtr and wave push 10 mtr back
ie after Every minute he travel 10 meter

after 18 minute he will be at 180meter
then in 19 minute he will reach at  200 meter

so answer is 19

If Aman takes 1 minute to swim 20 meters and a wave pushes him back 10 meters each time then he actually travels at a rate of 10 meters every 2 minutes. 200 meters / 10 meters = 20. (20)(2) = 40 minutes. His total travel time to reach the buoy is 40 minutes.
