An ideal gas is subjected to cyclic process involving four thermodynamic states, the amounts of heat (Q) and work
\( \mathrm{P} \) (W) involved in each of these states
\[
\begin{array}{l}
Q_{1}=6000 J, \quad Q_{2}=-5500 J ; \quad Q_{3}=-3000 J ; \quad Q_{4}=3500 J \\
W_{1}=2500 J ; \quad W_{2}=-1000 J ; \quad W_{3}=-1200 J ; \quad W_{4}=x J .
\end{array}
\]
W
The ratio of the net work done by the gas to the total heat absorbed by the gas is \( \eta \). The values of \( x \) and \( \eta \) respectively are

(a) \( 500 ; 7.5 \% \)
(b) \( 700 ; 10.5 \% \)
(c) \( 1000 ; 21 \% \)
(d) \( 1500 ; 15 \% \)
