Waec Model Questions Vol1 2025 Agricultural Science Question 15
Practice objective / multiple choice question 15 from the 2025 Waec Model Questions Vol1 Agricultural Science examination.
An extension officer plans a series of farmer field days (FFDs) to promote a new pest‑resistant maize variety to a community of 2 000 farmers. Adoption follows the logistic model P(t) = 1 / (1 + e^{-(k(t‑t₀))}), where k = 0.3 week⁻¹ and t₀ = 8 weeks. Each week the officer can directly demonstrate to 150 farmers, who adopt immediately. Every farmer who has adopted influences two other farmers per week; those influenced may adopt in the same week according to the logistic proportion P(t). The programme runs for 12 weeks. Estimate the total number of farmers who will have adopted the variety by the end of week 12. Give your answer as an integer (round down).
