A firm's records show: maximum consumption 120 units per day, minimum consumption 60 units per day, normal consumption 90 units per day. Lead time ranges from 10 to 16 days, with normal lead time of 12 days. Reorder quantity is 1,500 units. What is the minimum stock level?

Minimum stock level is reorder level less normal consumption during normal lead time. Reorder level is 1,920 and normal usage is 1,080, giving 840 units, which differs from the listed key.

  2. B1,080 units
  3. C1,920 units
  4. D540 units

Explanation

Minimum level = Reorder level − (normal consumption × normal lead time). Reorder level = maximum consumption × maximum lead time = 120 × 16 = 1,920. Normal usage during lead time = 90 × 12 = 1,080. Minimum level = 1,920 − 1,080 = 840. This gives 840, which is not among the options, so the key is not valid.
