Solved by EES Software. Solutions can be verified by copying-and-pasting the following lines on a blank EES screen. 
Q_in=600 "kJ/s"
TL=300 "K"
TH=1800 "K"
W_max=Q_in*(1-TL/TH) "kW"
 
"Some Wrong Solutions with Common Mistakes:"
W1_Wmax=W_max/2 "Taking half of Wmax"
W2_Wmax=Q_in/(1-TL/TH) "Dividing by efficiency instead of multiplying by it" 
W3_Wmax =Q_in*TL/TH "Using wrong relation" 
W4_Wmax=Q_in "Assuming entire heat input is converted to work"
