Ratio of the rate constants at temperatures $35\,^{\circ}C$ and $25\,^{\circ}C$

(C) The temperature coefficient of a reaction is defined as the ratio of the rate constants of the reaction at two temperatures differing by $10\,^{\circ}C$.Usually,it is taken as the ratio of rate constants at $35\,^{\circ}C$ and $25\,^{\circ}C$.Mathematically,$\text{Temperature coefficient} = \frac{K_{T+10}}{K_T} = \frac{K_{35\,^{\circ}C}}{K_{25\,^{\circ}C}} \approx 2$ to $3$ for most reactions.

Collision theory, Energy of activation and Arrhenius equation

For the reaction $A \to B$,$K_1 = 10^8 \, e^{-6000/8.34T}$ and for the reaction $P \to Q$,$K_2 = 10^{10} \, e^{-8000/8.34T}$. At what temperature $T$ will $K_1 = K_2$ (in $K$)?
