Ohh, I got it, you applied the natural logarithm on both sides of the equations.

Ok, I've got to the point you got, even though I thing I did some algebra error, look: n = ((6161.859/22000)+1)/ln(1.025) => n = 51.84078822

A is 60%, B is 40%, and they are disjoint sets.

I edited the question adding the details I forgot about A and B.
