Alord received a large order for stitching school uniforms from Mayflower 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 hours a day. Each of the May-flower uniforms requires 20 min. for cutting the fabric, one hour for stitching, and 15 min. for stitching buttons and button holes, whereas the Little Flower uniform requires 30 min., 1 hour, and 30 min. respectively for these activities.

(1) Tailor (2) Cutter (3) Assistant (4) Cannot be determined
Answers with Explanations
1. (3) No. of working hours for each person = 10 hour
∴Total time available for cutters in a day = 20 hours = 1200 mins.
Max. No. of uniform that 2 cutters can cut for Little Flower in a day = 1200/30 = 40
Time required for stitching 40 uniform = 40 x 60 = 2400 min and Alord has 5 tailors for stitching
that means the Total available time is (5 X 10 x 60) = 3000 mins.
Hence maximum number of Little Flower uniforms can be completed in a day = 40.
2. (1) To complete 20 Little Flower uniforms,
Time consumed by Cutters = 20 x 30 = 600 mins
Time consumed by Tailors = 20 x 60 = 1200 mins
Time consumed by Assistants = 20 x 30 = 600 mins
Time available for Cutters = (1200 – 600) = 600 mins
Time available for Tailors = (3000 – 1200) = 1800 mins
Time available for Assistant = (1200 – 600) = 600 mins
Max. No. of uniform that 2 cutters can cut for May Flowers uniform in a day = 600/20 = 30
Time required to stitch 30 uniforms = (30 x 60) = 1800 min and is exactly equal to the time
available for tailors. Hence No. of Mayflower uniform that can be completed on that day is 30.
3. (2) (1) 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.
4. (2) Hiring one more assistance increases the time available for stitching buttons and button holes.
Max. No. of uniform those cutter can cut for Mayflower in a day = 1200/20 = 60
Time required by Tailors to stitch 60 uniforms = (60 x 60) = 3600 mins, whereas time available is
3000 mins only.
Hence maximum No. of uniform that can be stitched in a day = 3000/60 = 50
Time consumed by assistant to stitch buttons to 50 uniform = (50 x 50) = 750 mins
Time available for assistant = (3 x 10 x 60) = 1800 mins.
Hence 50 uniforms can be completed in a day.
5. (1) Max. number of uniforms that can be cut by those 2 cutters in a day for MayFlower is 60. And the
buttons and buttonholes can be easily stitched by the 2 assistant for these 60 uniforms in a day in
the time available for them. While 5 tailors can stitch only 50 uniforms in the available time.
Hence, A lord will hire 1 tailor to get maximum increase in production capacity in a day.

Time required to stitch 30 uniforms = (30 x 60) = 1800 min and is exactly equal to the time

Time consumed by assistant to stitch buttons to 50 uniform = (50 x 50) = 750 mins
Time available for assistant = (3 x 10 x 60) = 1800 mins.
Hence 50 uniforms can be completed in a day.
5. (1) Max. number of uniforms that can be cut by those 2 cutters in a day for MayFlower is 60. And the
buttons and buttonholes can be easily stitched by the 2 assistant for these 60 uniforms in a day in
the time available for them. While 5 tailors can stitch only 50 uniforms in the available time.
