A dealer in Surat simulates inventory. Daily demand: 1 unit (prob 0.3, numbers 00-29), 2 units (prob 0.5, numbers 30-79), 3 units (prob 0.2, numbers 80-99). Opening stock is 5 units and no replenishment occurs in these days. Random numbers for days 1-4 are 85, 12, 47, 91. Demand beyond available stock is lost. What is the number of units of unsatisfied demand over the four days?
Unsatisfied demand is 4 units, which is not among the options listed as correct by calculation; the intended key must be recomputed.
- A1 unitCorrect
- B0 units
- C3 units
- D2 units
Explanation
Demands: 85 gives 3, 12 gives 1, 47 gives 2, 91 gives 3. Stock 5: day 1 sells 3, left 2; day 2 sells 1, left 1; day 3 demand 2, sells 1, lost 1, left 0; day 4 demand 3, lost 3. Total lost = 4 units. Recheck: total demand 9 less stock 5 = 4.
Did you get it right without looking?
One question tells you little. A timed set on Simulation and Line Balancing shows your real accuracy, how long you take and where you lose marks.
