A firm has 6 jobs to be processed on three machines A,B and C in the order ABC. The processing time of each job is given in the table below:- Find the idle time on different machines . Job Processing time [ hours ] Machine A Machine B Machine C J1 25 16 20 J2 26 20 19 J3 24 17 18 J4 22 20 21 J5 24 21 17 J6 28 18 13
- A.
74 , 31 , 58
- B.
31 , 58 , 60
Correct Answer
A. 74 , 31 , 58Explanation
The idle time on different machines can be calculated by subtracting the total processing time for each machine from the total available time. In this case, the total available time is the sum of the processing times for all the jobs.
For machine A, the total processing time is 25 + 26 + 24 + 22 + 24 + 28 = 149 hours. The total available time is 149 + 31 (idle time on machine B) + 58 (idle time on machine C) = 238 hours. Therefore, the idle time on machine A is 238 - 149 = 89 hours.
Similarly, for machine B, the total processing time is 16 + 20 + 17 + 20 + 21 + 18 = 112 hours. The total available time is 112 + 74 (idle time on machine A) + 58 (idle time on machine C) = 244 hours. Therefore, the idle time on machine B is 244 - 112 = 132 hours.
For machine C, the total processing time is 20 + 19 + 18 + 21 + 17 + 13 = 108 hours. The total available time is 108 + 74 (idle time on machine A) + 31 (idle time on machine B) = 213 hours. Therefore, the idle time on machine C is 213 - 108 = 105 hours.
Therefore, the idle time on different machines is 74 hours for machine A, 31 hours for machine B, and 58 hours for machine C.Rate this question:

The make-or-buy decision is not related with profit of the factory.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The make-or-buy decision is actually related to the profit of the factory. This decision involves analyzing whether it is more cost-effective for a company to produce a product or service in-house (make) or to outsource it from external suppliers (buy). By carefully considering factors such as production costs, expertise, quality control, and market conditions, a company can determine the most profitable option. Therefore, the statement that the make-or-buy decision is not related to the profit of the factory is false.Rate this question:
