Each of these 9 persons will work for exactly 10 hours a day. Each of the A. R. Academy uniform requires 20 minutes for cutting the fabric, 1 hour for doing the stitching and 15 minutes for stitching the buttons and the button holes. The T. M. High School uniform requires 30 minutes, 1 hour and 30 minutes respectively for the same activities.
