A pen costs  $\mathrm{Rs.}\, 13$  and a note book costs  $\mathrm{Rs.}\, 17$ . A school spends exactly  $\mathrm{Rs.}\, 10000$  in the year  $2017-18$  to buy  $x$  pens and  $y$  note books such that  $x$  and  $y$  are as close as possible (i.e.,  $|x-y|$  is minimum). Next year, in  $2018-19$ , the school spends a little more than  $\mathrm{Rs.}\, 10000$  and buys  $y$  pens and  $x$  note books. How much **more** did the school pay?
