Question 5 The weekly output of a production process is shown in Table 1, together with data for labour and material inputs. The standard inventory value of the output is RM135 per unit. Overhead is charged weekly at the rate of RM1600 plus 0.5 times direct labour cost. Assume a 40-hour week and an hourly wage of RM26. Material cost is RM20 per running metre.
