QUESTION 3 3.1 A time study of a finishing operation yielded the following observed times for one element (element C) of a job with a performance rating of 90%. There is an allowance of 17% for this operation. Element C Observed Times: Observation Time (minutes) 1 9 2 9 3 8 4 10 5 11 3.1.1 Calculate the observed time for element C. 3.1.2 Calculate the normal time for element C. 3.1.3 Calculate the allowance time for element C. 3.1.4 Calculate the standard time for element C. 6 8 7 8 8 9 9 12 10 7 Total 3.2.3 Suppose the operator produced 550 units during an eight hour shift. Calculate wages earned by the operator. 91 3.2 In developing standards for one operation, a time-study analyst observed an operator for 30 minutes during which the operator completed 52 parts. The analyst rated the worker at 90%. The base wage for the operator is R22 per hour and the firm's policy is to assign a 11% total operator allowance for fatigue and contingencies. Given the above information, calculate the following: 3.2.1 The Normal Time for the task. 3.2.2 The Standard Time for the task. (3) (3) (6) [20]
