Two heat engines are operating in such a way that the heat rejected by the first engine is used as the heat input of the second. If both the engines are

40 \%

efficient, then the overall efficiency of the system is

View answer and explanation

Correct option: A

0.64

Option A (0.64) is correct because the overall efficiency is the product of the individual efficiencies when engines are operating in series.
