    Two Carnot engines $A$ and $B$ are operated in succession. The first one, $A$ receives  heat from a source at $T_1 = 800\, K$ and rejects to sink at $T_2K$. The  second engine $B$ receives heat rejected by the first engine and rejects to another sink  at $T_3 = 300\, K$. If the work outputs of two engines are equal, then the value of $T_2$ is ...... $K$
