The normal loss in process 1 is 10% of input, and there are no expected losses in the other processes. Scrap value in process 1 is £0.50 per litre. The costs incurred in process 1 are appor¬ tioned to each product according to the volume of output of each product. Production overhead is absorbed as a percentage of direct wages.
