I guess you should try to find an equation for the concentration of liquid B in the first tank as a function of time. Once you have that, I think you can use your previous result for each successive tank.
This is the easiest aproach and works in principle. not sure how complicated the calculations gets as you go on.
Otherwise it seems like the kind of problem that you should solve as simultaneous differential equations. That is, you put up your system of linear differential equations, and then you use the machinery with matrices where you find eigenvectors, eignevalues etc and then exponentiate to find solution. If your course doesnt cover that, i reccomend the first solution.
