A firm operates a process in which no losses are incurred. At the beginning of the period the opening work-in-progress was 2 500 units, which were 100 per cent complete in respect of materials, and 60 per cent complete in respect of labour and overheads. During the period, 6 500 units were completed. At the end of the period the closing work-in-progress was 1 500 units, which were 100 per cent complete in respect of materials, and 60 per cent complete in respect of conversion. The firm uses the weighted average method for valuing the output from the process. Calculate the number of equivalents units completed in respect of labour and overheads.
