Hello candidate,
In the given question, it's mentioned that ratio of thermal condivities of two rods of different materials 5:4, but you have no provided no specific question for it.
The two rods have the resistances in the order of 4:5 because the Resistances are inversely proportional to the ratio of their respective conductivities.
Hope it helps!!
Question : If the ratio of the volumes of two cylinders is 7 : 5 and the ratio of their heights is 5 : 7, then what is the ratio of their radii?
Option 1: 5 : 7
Option 2: 3 : 4
Option 3: 5 : 9
Option 4: 4 : 5
