Neco 2019 Geography Question 18

An industry plans to produce 5,000 units per month of a product. Each unit requires 2\,tonnes of raw material and the finished product weighs 0.5\,tonnes for transport. The raw material is sourced from Supplier\,X located 120\,km away, and the finished product is sold to Market\,Y located 80\,km away.\n\nTwo possible plant locations are considered:\n\n- Location\,A: 30\,km from Supplier\,X, 70\,km from Market\,Y; labour cost \(\text{₦}150\) per worker per day; requires 120 workers; operates 22 days per month.\n\n- Location\,B: 90\,km from Supplier\,X, 40\,km from Market\,Y; labour cost \(\text{₦}130\) per worker per day; requires 150 workers; operates 22 days per month.\n\nTransport cost per tonne‑km is \(\text{₦}0.75\) for raw material and \(\text{₦}0.60\) for the finished product.\n\nCalculate the total monthly cost (transport of raw material + transport of finished product + labour) for each location, identify the cheaper location, and give the cost difference (cheaper minus more expensive) in Naira, rounded to the nearest Naira.
