Neco 2017 Agricultural Science Question 38
Practice objective / multiple choice question 38 from the 2017 Neco Agricultural Science examination.
A fast‑growing forest stand has an initial volume of 120 m³/ha. Its annual volume growth follows \(V(t)=120(1.08)^{t}\) where \(t\) is the number of years after planting. The net revenue from harvested timber is \(\text{₦}2,500\) per m³ and a re‑planting cost of \(\text{₦}30,000\) per ha is incurred after each harvest. The rotation must be at least 5 years to obtain marketable timber. Determine the rotation age (in whole years) that maximizes the average annual net revenue, and state that maximum average annual net revenue (to the nearest naira).
