An ideal gas after going through a series of four thermodynamic states in order, reaches the initial state again (cyclic process). The amounts of heat, Q and work, W involved in these states are Q, =6000J, 42 =-5500J , Q3 = -3000 J, Q, =3500 W, =2500J, W2 =-1000J, Ws =-1200J, IN, =x J The ratio of net work done by the gas to the total heat absorbed by the gas is r. Calculate the value of x and n.
