An ideal gas is taken through a cyclic thermodynamical process through four steps. Amounts of heat involved in these steps are : Q₁ = 5960 J, Q₂ = -5585 J, Q₃ = -2980 J and Q₄ = 3645 J respectively. The corresponding works involved are : W₁ = 2200 J, W₂ = - 825 J, W₃ = -1100 J and W₄ respectively. Value of W₄ is:
