Population of state $X$ increased by $x \%$ and the population of state $Y$ increased by $y \%$ from 2001 to $2011 .$ Assume that $x$ is greater than $y .$ Let $\mathrm{P}$ be the ratio of the population of state $\mathrm{X}$ to state $Y$ in a given year. The percentage increase in $P$ from 2001 to 2011 is
(A) $\frac{x}{y}$
(B) $x-y$
(C) $\frac{100(x-y)}{100+x}$
(D) $\frac{100(x-y)}{100+y}$
