An ideal gas is taken through a cyclic thermo dynamical process through four steps. The amounts of heat involved in steps are Q₁ = 5960J, Q2 = -5585J, Q3 = -2980J, Q4 = 3645J ; respectively, the corresponding works involved are W₁ = 2200, W₂ = -825J, W3= -1100J and W4 respectively. Find the value of W4 and efficiency of the cycle A 1315 J, 10% B 765 J, 11% C both of them D none of these
