Neco 2022 Agricultural Science Question 2
Practice objective / multiple choice question 2 from the 2022 Neco Agricultural Science examination.
A farmer has 1,200 mango trees. Initially 8\% of the trees are infected by a fungal disease. A fungicide application reduces the number of infected trees by 60\% of the current infected trees. Each application costs N150 per hectare, and each hectare contains 100 trees. After each application, 5\% of the remaining healthy trees become newly infected. The farmer can apply the fungicide at most two times. Assuming both applications are made, calculate the expected number of healthy trees after the second application (round to the nearest whole tree) and the total cost of the fungicide.
