Two rods of material, `x` and two of `y` are connected as shown in the figure. All the rods are indentical in length and cross-sectional area. If the end `A` is maintained at `80^(@)C` and the end `D` is maintained at `10^(@)C`, calculate the temperature of the junctions `B` and `C` in the steady state. Thermal conductivity of `x` is double that of `y`.
