DIRECTION FOR QUESTIONS:

Answer the questions based on the following information.

Alord received a large order for stitching school uniforms from May Flower School and Little Flower School. He has two cutters who will cut the fabric, five tailors who will do the stitching, and two assistants to stitch the buttons and button holes. Each of these nine persons will work for exactly 10 hr a day. Each of the May Flower uniforms requires 20 min for cutting the fabric, 1 hr for stitching, and 15 min for stitching buttons and button holes, whereas the Little Flower uniform requires 30 min, 1 hr, and 30 min respectively for these activities.

Question: If Alord decides to complete 30 Little Flower uniforms only and no other on a particular day, how many total man-hours will be idle?

Explanation:

To complete 30 Little Flower uniforms,
Time consumed by Cutters = (30 x 30) = 900 mins
Time consumed by tailors = (30 x 60) = 1800 mins
Time consumed by assistants = (30 x 30) = 900 mins
Time available for cutters = (1200 – 900) = 300 mins
Time available for tailors = (3000 – 1800) = 1200 mins
Time available for Assistant = (1200 – 900) = 300 mins
As they are not working in this available time it is the idle time.
Hence total man hours that are idle = (300 + 1200 + 300) = 1800 mins = 30 hours.

Hence, option 2 is the correct answer.
