Question: At a workcenter, two types of jobs are to be done - 'A' and 'B'. 'A' needs a setup time of 20 minutes, and a per piece time of 2 minutes. 'B' needs a setup time of 25 minutes, and a per piece time of 3 minutes. They have been alternating between ten units of A and ten units of B. Instead, if they alternate between 20 units of A and 20 units of B, what is the percentage increase in productivity? (Both A and B are priced equal, so for the total output, you can add the two) (Please provide two decimal places)
