Neco 2022 Mathematics Question 42
Practice objective / multiple choice question 42 from the 2022 Neco Mathematics examination.
The cost \(C\) (in Naira) of producing \(x\) units of a product varies directly with the square of \(x\) and inversely with the number of workers \(w\) employed. When 500 units are produced by 20 workers, the cost is \(\text{₦}12{,}000\). Find the cost when 800 units are produced using the same number of workers. Also, if the company wishes to keep the cost at \(\text{₦}12{,}000\) while producing 800 units, how many workers are required (to the nearest whole worker)?
