Answer:

Strike441 [17]

Answer:

Option (A) is correct.

Explanation:

Given that,

Mean daily demand, M = 20 calculators per day

Standard deviation, SD = 4 calculators per day

Lead time for this calculator, L = 9 days

z-critical value (for 95% in-stock probability) = 1.65 (From z tables)

Normal consumption during lead-time:

= Mean daily demand × Lead time

= 20 × 9

= 180 units of calculator

Safety Stock = z value × SD × L^(0.5)

                     = 1.65 × 4 × (9)^(0.5)

                     = 1.65 × 4 × 3

                     = 19.8 units

Reorder Point = Normal consumption during lead-time + Safety Stock

                        = 180 units  + 19.8 units

                        = 199.8 or 200 units (Approx)
