Q.2 The product of a company passes through three distinct processes called A, B and C. From the past experience, it is ascertained that wastage is incurred in each as under:
Process A – 2%, Process B – 5%, Process C – 10%
The percentage of wastage is computed on the number of units entering process concerned. The wastage of each process possesses a scrap value. The wastage of Process A and B is sold at Rs 5 per 100 units and that of Process C at Re 0.20 per unit.
The following information was obtained for the month of March, 2009.
20,000 units of crude material were introduced in Process A at a cost of Rs 8,000.
