The loss in each process resulted from evaporation due to heating or due to spillage and hence nothing of value could be realized from these losses. There were no stocks of materials or Work-in-Progress at the beginning or end of the month. The output of each process passes directly to the next process at cost without any provision for internal profit. Manufacturing overheads are absorbed by each process at 25% of direct labour cost.
