Final Answer :
E
Explanation :
The correct number of kanbans can be calculated using the formula: Number of Kanbans=Demand during lead time+Safety stockSize of one container \text{Number of Kanbans} = \frac{\text{Demand during lead time} + \text{Safety stock}}{\text{Size of one container}} Number of Kanbans=Size of one containerDemand during lead time+Safety stock . Here, demand during lead time is 2 days×10 cakes/day=20 cakes2 \text{ days} \times 10 \text{ cakes/day} = 20 \text{ cakes}2 days×10 cakes/day=20 cakes , and safety stock is 0.5 day×10 cakes/day=5 cakes0.5 \text{ day} \times 10 \text{ cakes/day} = 5 \text{ cakes}0.5 day×10 cakes/day=5 cakes . Thus, 20 cakes+5 cakes1 cake/container=25 \frac{20 \text{ cakes} + 5 \text{ cakes}}{1 \text{ cake/container}} = 25 1 cake/container20 cakes+5 cakes=25 kanbans.
