Two rods X and Y of identical dimensions are at temperature $\displaystyle 40^{\circ} \mathrm{C}$. If X is heated upto $\displaystyle 200^{\circ} \mathrm{C}$ and Y is heated upto $\displaystyle \mathrm{T}^{\circ} \mathrm{C}$, then also the new lengths are the same. If the ratio of the coefficients of linear expansion of X and Y is $\displaystyle 8$ : $\displaystyle 10$ then the value of T is \_\_\_\_ K.
