$A$ spider climbed $62 \frac{1}{2} \%$ of the height of the pole in one hour and in the next hour it covered $12 \frac{1}{2} \%$ of the remaining height. If the height of the pole is $192 \, m$,then the distance climbed in the second hour is:

The population of a variety of tiny bushes in an experimental field increased by $10 \%$ in the first year,increased by $8 \%$ in the second year,but decreased by $10 \%$ in the third year. If the present number of bushes in the experimental field is $26730$,then the number of bushes in the beginning was:

$125 \%$ of $320 + x \%$ of $125 = 440$. Find the value of $x$.
