Using the slack per remaining operations (S/RO) rule, we calculate the slack for the remaining operations for each job:

Job A: (10-0) + (16-4) = 22 
Job B: (16-0) + (12-4) = 24 
Job C: (12-0) + (10-4) = 18

Job B has the highest S/RO value and should be processed first. After processing Job B, the remaining slack per remaining operations would be: 
Job A: (10-4) = 6 
Job C: (10-4) = 6

Both Job A and Job C have the same remaining slack per remaining operations, but Job C has a shorter processing time and should therefore be processed before Job A.

Therefore, the sequence of jobs processed at Workstation 1 should be: C-B-A.
