i think op is asking about the proverbial river situation where he always has a polarized range and opponent always has a bluff catcher. he wants to know sizing to make opponent indifferent (point of nuetrality) with a fixed range consisting of 12 value hands and 4 bluffs. as masque pointed out, its usually not quite that simple outside of a toy game.
i posted yesterday but ended up deleting because i figured someone else could explain better than i can. but after seeing this i thought i better pop back in and clear things up, or maybe learn something myself! im not really sure whats going on here ron.

1200/4 -100 =Bet size
Bet size =200
If you have the same bluff combos as value combos:
1*(100+Bet) = 1*100
100 - 100 = bet
=0.... If your perfectly balanced it makes no difference
0bluff Combos:
0*(100+bet)=1*100
100/0 -100 = infinity.....size would have to be infinitely big to call....
Hope this helps
if we bet 200 into 100 on river then opponents ev of call would be (300*.25)+(-200*.75)= -75
opponent could attain a higher ev (0) by folding.
we want to find the case where opponent cant improve his ev regardless of what he does. lets try setting our equation to 0 and see what that provides.
0=(100+x)(.25)+(-x)(.75)
x=50
if we bet 50 into 100 then opponents ev is 0.
if he folds, again his ev is still 0, so its neutral.
