    Two Carnot engines $A$ and $B$ are operated in series. Engine $A$ receives heat from a reservoir at $600\,K$ and rejects heat to a reservoir at temperature $T$. Engine $B$ receives; heat rejected by engine $A$ and in turn rejects it to a reservoir at $100\,K$. If the efficiencies of the two engines $A$ and $B$ are represented by ${\eta _A}$ and ${\eta _B}$ respectively, then what is the value of $\frac{{{\eta _A}}}{{{\eta _B}}}$
