Two Carnot engines A and B are operated in series. The engine A receives heat from the source at temperature T₁ and rejects the heat to the sink at temperature T. The second engine B receives the heat at temperature T and rejects to its sink at temperature T₂. For what values of T the efficiencies of the two engines are equal

$${{{T_1} - {T_2}} \over 2}$$

$${T_1}{T_2}$$

$$\sqrt {{T_1}{T_2}} $$

$${{{T_1} + {T_2}} \over 2}$$
