A) \[11.1%\]
B) \[22.2%\]
C) \[33.3\,%\]
D) \[44.4\,%\]
Correct Answer: B
Solution :
Maximum efficiency of an engine working between temperatures \[{{T}_{2}}\,\,and\,\,{{T}_{1}}\] is given by \[\eta =\frac{{{T}_{2}}-{{T}_{1}}}{{{T}_{2}}}=\frac{383-293}{383}=\frac{85}{383}=0.222\] \[\eta \,\,=\,\,22.2\,%\]
