If the first location visited from the warehouse is Ahmednagar, then what is the chance that the total distance covered in the route is 40 km?
Explanation:
Demand A – 50 (40%); 70 (60%) B – 40 (30%); 60 (70%) C – 70 (30%); 100 (70%) D – 30 (40%); 50 (60%)
If first city visited is Ahmednagar, this is possible when A’s demand is highest. This is only possible when A’s demand is 70.
∴ Demand at C should be 70 Demand at B = 40 or 60 Demand at D = 30 or 50
∴ Sequence of cities can be A → C → B → D: distance travelled = 38 kms A → C → D → B: distance travelled = 40 kms
∴ Demand at D ≥ B ⇒ Demand at D = 50 (60%) and demand at B = 40 (30%)
⇒ Required possibility = 60% × 30% = 18%
Hence, option (c).
