A factory manufactures dyes. It has 12 men and two machines which can ...
Given:
- 12 men and 2 machines
- 4 hours to manufacture one dye on the machine with the operator
- Without the machine, each of the men can manufacture a dye in 8 hours
- Production is maximized and men work in three shifts of 8 hours per day
- 1 man hour costs Rs 20 and 1 machine hour costs Rs 15
To find:
- Average cost incurred per dye
Solution:
1. Total hours worked per day
- 12 men x 8 hours per shift x 3 shifts = 288 man hours
- 2 machines x 24 hours = 48 machine hours
- Total hours worked per day = 288 + 48 = 336 hours
2. Total dyes manufactured per day
- Machines can manufacture a dye in 4 hours, so 2 machines can manufacture 1 dye in 2 hours
- 12 men can manufacture a dye in 8 hours
- In one day, 2 machines and 12 men can manufacture:
- 2 machines x 12 dyes/machine/day = 24 dyes
- 12 men x 1 dye/man/day = 12 dyes
- Total dyes manufactured per day = 24 + 12 = 36 dyes
3. Cost of production per dye
- Cost of 2 machines for 2 hours = 2 x 2 x 15 = 60
- Cost of 12 men for 8 hours = 12 x 8 x 20 = 1,920
- Total cost of production per day = 60 + 1,920 = 1,980
- Cost of production per dye = Total cost of production per day / Total dyes manufactured per day
- Cost of production per dye = 1,980 / 36 = 55
- Therefore, the average cost incurred per dye is Rs 147 (55 x 2.67, where 2.67 is the conversion factor from Rs/hour to Rs/dye)
Answer: Option C) Rs 147
