Q6. (a) A company manufacture refrigerators at the rate of 500 units per week, and the standard cost of a material used in their manufacture for 2000 units is expected to be: 1200 kg (0.6 kg per unit) @ 1.75 per kg = 2100 During the month of February production data showed that 1800 units were produced that required 1000 kg of material and the purchase price was 1.60 per kg. (0) (11) Calculate the adjusted standard costs for production based upon this material data (2 marks) Calculate all three of the material variances. Prior to calculating these variances, clearly indicate the values for each term to be used in any equations (7 marks) (b) (6) In Method Study, identify the principle definition of a Storage action, and state the recognised key difference that differentiates Storage from a Delay (or Temporary Storage)? (2 marks) Identify, illustrate the symbol used, and fully explain the key features of the 3 other principal symbols used in Process Charts defining what each definition does or does not include if appropriate (9 marks) (ID) (c) 0) The Superfast Production Company make clock radios. Customer demand dictates that a production level of 192 clock radios per hour is needed, and the company know from experience that it takes 6 Standard Minutes to produce each clock radio. By determining the time taken per clock radio, using the production rate indicated, calculate how many operators will be required to manufacture the clock radios, assuming that there is 100% efficiency in the manufacturing process activity. (3 marks) What other assumptions are being made about the operators and their tasks if we use this number of operators? (2 marks)
