The efficiency of a heat engine if the temperature of source 127∘ C and that of sink is 27∘ C nearly

The efficiency of carnot's heat engine is 0.5 when the temperature of the source is T_(1) and that of sink is T_(2) .The efficiency of another crot's heat engine is also 0.5.the temperature of source and sink of the second engine are respecitvely

A scientist says that the efficiency of his heat engine which operates at source temperature 127^(@)C and sink temperature 27^(@)C is 26% , then

The efficiency of a carnot heat engine is 0.6 when the absolute temperatures of the source and sink are T_(1) and T_(2) respectively. The efficiency of another carnot engine is also 0.6 but the source and sink temperatures are different. What are the temperatures of the source and the sink of the other engine ?
