Percent problems

At the beginning of the therapy, three monitored patients were of the same weight. Their weights were changing as follows: (a) Patient A gained $6\mathrm{\%}$ of his weight and then his weight did not change. (b) Patient B lost $2\mathrm{\%}$ of his weight first, but later he gained $8\mathrm{\%}$ of his weight. (c) Patient C gained $2\mathrm{\%}$ of his weight and later he gained another $4\mathrm{\%}$ of his weight. Which patient has the lowest weight after the therapy?
