Neco 2023 Agricultural Science Question 25

An extension officer plans a 12‑month programme to promote integrated pest management for yam farmers in a district with 1,200 yam growers. The programme includes three activities:\n\n1. Radio broadcasts: cost \u20A5150,000 per month, each broadcast reaches 70\% of the farmers.\n2. Farmer field schools: cost \u20A5250,000 per session, each session is attended by 25 distinct farmers, with a maximum of 8 sessions per year.\n3. Printed pamphlets: cost \u20A530 per pamphlet, each pamphlet is given to one farmer and reaches 60\% of the farmers.\n\nThe total budget is \u20A52,500,000 for the year. The officer wants at least 90\% of the farmers (i.e., at least 1,080 farmers) to be reached by at least one activity, and the total number of farmer‑contact events (each broadcast counts as one contact per farmer reached, each field‑school session counts as one contact per attending farmer, each pamphlet counts as one contact) should be at least 1.5 times the number of farmers reached. Determine one feasible combination of (i) number of months of radio broadcasts, (ii) number of field‑school sessions, and (iii) number of pamphlets printed that satisfies the budget, coverage and contact‑frequency constraints. State the chosen numbers, the total cost, the total distinct farmers reached and the total contacts.
