A Carnot engine A operates between temperature $T_1$ and $T_2$ ($T_1>T_2$). A second Carnot engine B uses all the heat rejected by A as input and input and operates between temperature $T_2$ and $T_3$ ($T_2>T_3$). What will be the efficiency of the coupled engine system ?

It should be the same as one Carnot engine operating between $T1$ and $T3$.

Hope this helps
