°C and 27°C, respectively. The efficiency of the heat engine can be calculated using the formula:

Efficiency = 1 - (T_sink / T_source)

where T_sink and T_source are the temperatures of the sink and source, respectively.

Plugging in the given values, we get:

Efficiency = 1 - (27 + 273) / (127 + 273) = 1 - 300 / 400 = 1 - 0.75 = 0.25 = 25%

Therefore, the efficiency of the heat engine is 25%.
