I guess it is going as 1 -> 1/2 -->1/4-->1/8 till 19 terms

t19 = a x r ^ (n-1)
= 1 x 1/2 ^ 18
= 1/250 mL
First take: 640 (50M, 27V) - RC needs 300% improvement
Second take: coming soon..

HSPA.

Found this wonderful explanation

But its beyond scope of the GMAT IMO. Couldn't solve it in < 2mins..

initially let x litres of wine is present

1) after first operation we will have
x-(x/x) = (x-1)x/x litres of wine & total solution = x+1
2) after second operation we will have
(x-1)-(x-1)/(x+1) = (x-1)x/(x+1) & total solution = x+2
3) after third operation we will have
((x-1)x/(x+1)) - ((x-1)x/(x+1))/(x+2) = (x-1)x/(x+2) & total solution = x+3
.
.
at this step i can see the pattern
so at 19th step
19)(x-1)x/(x+18)
since x = 3 => 2*3/21 = 2/7

nice problem
