There are two bottles of salt water of different concentrations, AB. Xiao Ming takes 1 liter from each bottle and mixes them together to obtain a bottle of salt water with a concentration of 36%. He then mixes this salt water with 2 liters of salt water in bottle A to obtain the final concentration is 32%, so what is the concentration of the brine in bottle B?
