Two rectangular blocks A and B of different metals have same length and same area of cross-section. They are kept in such a way that their cross-sectional area touches each other. The temperature at one end of A is \[100{}^\circ C\]and that of B at the other end is\[0{}^\circ C\]. If the ratio of their thermal conductivity is 1:3, then under steady state, the temperature of the junction in contact will be (in \[{}^\circ C\])?
