Two rods $A$ and $B$ of identical dimensions are at a temperature of $30 °\mathrm{C}$. If $A$ is heated upto $180 °\mathrm{C}$ and $B$ up to $T$ (measured in $°\mathrm{C}$) then the new lengths are the same. If the ratio of the coefficients of linear expansion of $A$ and $B$ is $4:3$, then the value of $T$ is
