Re-order quantity (RQ) is calculated using the formula: $$\text{RQ}=(\text{Maximum consumption during lead time}+\text{Safety stock})-\text{Re-order level}$$

Steps:

1. Maximum consumption during lead time:

   • Average re-order period = $\frac{10+30}{2}=20$ days
   • Maximum consumption = $400\times 20=8000$ units

2. Safety stock:

   • Not explicitly given, so assumed 0 (as no buffer is mentioned).

3. Re-order quantity: $$\text{RQ}=(8000+0)-6000=2000\text{ units}$$

However, the maximum stock level constraint must be satisfied: $$\text{Maximum stock level}=\text{Re-order level}+\text{Re-order quantity}$$ $$10000=6000+\text{RQ}⟹\text{RQ}=4000\text{ units}$$

**Final re-order quantity: ** 4000 units
