Gautum must have made a calculation mistake somewhere .In his calculation of the efficiency of the heat engine,he created,he has derived the expression $e=(T_H+T_C)/(T_H+2T_C)$.$T_H$ is temparature of heat source and $T_C$ is temparature of cold sink.
State the law of thermodynamics that this expression violates,and explain why.
