1) half of 6400 = 3200 he bet 3200 and won 3200 thus total 9600
2) half of 9600 = 4800 he lost in bet.
3) half of 4800= 2400he bet and he won 2400 thus total is 7200
4) half of 7200= 3600 he lost in bet
5) half of 3600=1800 he bet and won 1800 thus total is 5400

We can assume any no. Of event to be a win or a loss. The result is always same.
Let us consider that he lost first 3 consecutive games and won last 3.
Amount remaining after 3 loss= 6400*(1/2)*(1/2)*(1/2)=800
Amount after winning in round 4= 400+(400*2)=1200
Amt after win in round 5= 600+(600*2)=1800
Amt after win in round 6= 900+(900*2)=2700 Ans.
