JEE Advanced 2023 Chemistry question on Equilibrium

In a one-litre flask, 6 moles of A undergoes the reaction A (g) $\rightleftharpoons$ P (g). The progress of product formation at two temperatures (in Kelvin), $T_1$ and $T_2$, is shown in the figure:

If $T_1 = 2T_2$ and $\left(\Delta G_2^\theta - \Delta G_1^\theta\right) = RT_2 \ln x$, then the value of x is ___.

[$\Delta G_1^\theta$ and $\Delta G_2^\theta$ are standard Gibb's free energy change for the reaction at temperatures $T_1$ and $T_2$, respectively.]
