Actual fixed manufacturing overheads amount to R296 800 per annum. Sung Industries uses material cost as basis to allocate the fixed manufacturing overheads. Over- or under allocated manufacturing overhead are written off against the cost of sales in the year they are incurred. Variable administration overheads vary according to the number of units sold. Assume that all financial data for April 20x1 (both budgeted and actual for the sake of simplicity in explaining the concept) remain constant during the three years in question. You are required to: 3.1 Compile income statement using the direct costing method for the 3 years in question (30)
