Neco 2020 Agricultural Science Question 26
Practice objective / multiple choice question 26 from the 2020 Neco Agricultural Science examination.
A farmer needs exactly 120 kg of nitrogen (N), 60 kg of phosphorus as \(P_{2}O_{5}\) and 40 kg of potassium as \(K_{2}O\) for a field. He can buy two types of fertilizer, each sold in 50 kg bags:\n\n- Fertilizer A contains 20 % N, 10 % \(P_{2}O_{5}\) and 5 % \(K_{2}O\) and costs \(\₦500\) per bag.\n- Fertilizer B contains 10 % N, 20 % \(P_{2}O_{5}\) and 15 % \(K_{2}O\) and costs \(\₦450\) per bag.\n\nDetermine the integer number of bags of each fertilizer the farmer should purchase so that all three nutrient requirements are met **exactly** and the total cost is minimum. State your answer as "\(a\) bags of A and \(b\) bags of B".
