ABC Co. Ltd. Working at 50% capacity manufacturing 12,000 units of a product
cost is Rs. 200 and selling price is Rs. 220. The other information is as follows:
Cost per unit (Rs.)
Raw material
100
Wages
40
Factory overhead
40 (40% fixed)
3
Administration overhead 20 (50% fixed)
At 60% capacity raw material cost goes up by 2% and sales price falls by 2%. At
80% capacity the raw material cost increase by 5% and sales price decrease by
5%. Prepare a statement to show profitability at 60% and 80% capacity.
