      Hi Vidhi,

      This question is equivalent to asking one to maximize the value of a fraction of the form $\frac{m}{n}$, and to do so we should choose to make $m$ as large as possible, and $n$ as little as possible, so that the resulting fraction has the greatest possible value. Does this make sense?
