In the vicinity of the triple point, the equation of liquid-vapour boundary in the $\text{P-T}$ phase diagram for ammonia is $ \ln p=24.38-3063/T$, where $\text{P}$ is pressure (in $\text{Pa}$) and $\text{T}$ is temperature (in $\text{K}$). Similarly, the solid-vapour boundary is given by $\ln p=27.92-3754/T$. The temperature at the triple Point is _______________ $\text{K}$ ($\textit{round off to one decimal place}$).
