vered of 100 stion Shazrul the founder, developed while in college. He began producing t-shirt for friends, hand-printed with college colors and logos. As demand grew, he hired some workers and began to manage the operation. Currently STC sells its T-shirt to brand-name clothes retailers in Melaka. The company uses two direct cost categories: direct material and direct labour. For labours, STC has some employees who have been with the company for a very long time and others who are newly joined and inexperienced. The company uses standard costing for the t-shirt cost per unit A typical standard hour per t-shirt is expected to take 1.25 hours of labour at the standard wage rate is RM12.00 per hour. The standard material of a t-shirt requires 3 meters of fabric X. The standard price of fabric X used to produce a t-shirt is RM2.30 per meter. The production manager, Mr. John, is responsible for the purchasing of materials and any issues relating to production. However, he is not responsible for the setting of standards costs At the end of May 2021, 122,000 units of t-shirt were produced. Direct materials used were 2.8 meters per unit. The actual direct material cost was RM2.46 per meter. The actual direct labor-hours used was 13 hours per unit, at an actual wage of RM12.60 per hour. After the end of May 2021 period, STC decided to revise the standard costs retrospectively to take account of the following: 1. A 3 percent increase in the direct material price per kilogram. 2. A labour rate increase of 4 percent 3. The standard for labour efficiency had anticipated buying a new machine leading to a 10 percent decrease in labour hours; instead of buying a new machine, existing machines had been improved, giving an expected 5 percent saving in material usage. As the management accountant in STC, you have been asked by Mr. Shazrul to prepare a variance analysis report for him to measure the performance of the production manager. Required: (show all calculations) Note: You may use up to 3 decimal places. a. For the month of May 2021, compute the following variances: O ACC 1. Material price planning variance (2.25 marks) ii. Material price operational variance (15 marks) iii. Material usage planning variance. (2.5 marks) iv. Material usage operational variance (1.75 marks) V. Labour price planning (2.25 marks) vi. Labour price operational (1.5 marks) MSi 3.
