Neco 2024 Agricultural Science Question 18
Practice objective / multiple choice question 18 from the 2024 Neco Agricultural Science examination.
In a lake stocked with tilapia, the biomass \(B\) (tons) follows the logistic growth equation \(\frac{dB}{dt}= rB\left(1-\frac{B}{K}\right)-H\) where \(r = 0.4\) yr\(^{-1}\), carrying capacity \(K = 500\) tons and \(H\) is the constant annual harvest (tons yr\(^{-1}\)). The market price is ₦250,000 per ton and the cost of harvesting is ₦80,000 per ton.\n\nDetermine the harvest level \(H\) (tons per year) that maximizes annual profit and compute the maximum profit. Express the harvest to the nearest ton and profit to the nearest thousand Naira.
