Work Measurement - 2018

Question 3: In a work measurement exercise, an operation is studied to find the Standard Time for that operation. In this study, observed time and rating are given for five observations. Observed time in five observations were 2 minutes, 1.5 minutes, 4 minutes, 3 minutes and 2.5 minutes. The corresponding ratings recorded by the work measurement team were 110, 180, 70, 90 and 90 respectively. This operation requires a lot of physical and mental concentration. Hence, a 30% allowance is given to get the Standard Time.
