Question

Quizplus · Accepted Answer

To produce 1 unit, the time required is:

Mixing department + Molding department + Casting department + Finishing department
= 3 + 5 + 7 + 4
= 19 minutes

However, there are also wait times and move/pre-wait times between departments, which must be added.

Total time for 1 unit = 19 + 8 + 5 + 10 + 12
= 54 minutes

To produce 20 units, we need to multiply this time by 20:

Total time for 20 units = 20 x 54
= 1080 minutes

Therefore, the correct answer is B) 415 minutes, as none of the other options are close to the correct calculation.
