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} C and 40^{\circ} 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): [22 Jan 2026 Shift 1]

Correct Answer is : 89∘C and 73∘C respectively

60^{\circ} C and 45^{\circ} C respectively

80^{\circ} C and 70^{\circ} C respectively

89^{\circ} C and 73^{\circ} C respectively
