Two cylindrical rods A and B made of different materials, are joined in a straight line. The ratios of lengths, radii and thermal conductivites of these rods are: \frac{L_A}{L_B}=\frac{1}{2}, \frac{r_A}{r_B}=2 and \frac{K_A}{K_B}=\frac{1}{2}. The free ends of rods A and B are maintained at 400 {\K}, 200 {\K}, respectively. The temperature of rods interface is \_\_\_\_ K, when equilibrium is established. [7 Apr 2025 Shift 2]
