Question

Rods $$x$$ and $$y$$ of equal dimensions but of different materials are joined as shown in figure. Temperatures of end points **$$A$$** and **$$F$$** are maintained at **$$100^\circ	ext{C}$$** and **$$40^\circ	ext{C}$$** respectively. Given the thermal conductivity of rod **$$x$$** is three times of that of rod **$$y$$**, the temperature at junction points **$$B$$** and **$$E$$** are (close to):
