Respuesta :

Answer:

option (B) 100

Explanation:

Data provided in the question:

Number of days supplier takes to deliver an order once it has been placed i.e the lead time = 25 days

Standard deviation of daily demand = 20

Now,

Standard deviation of usage during lead time

= Standard deviation of daily demand × √(Lead time)

= 20 × √25

= 20 × 5

= 100

Hence,

The answer is option (B) 100
