Concept:Average revenue per man employed is the revenue earned by each worker, found by dividing total revenue by the number of men.Explanation:When 6 men are employed, the total product is 660 units. Price per unit is N2. Total revenue =660×2=N1320. Average revenue per man =6N1320=N220. Alternatively, average product =6660=110 units. Average revenue =110×N2=N220. The earlier solution ignored the price per unit; dividing 660 by 6 only gives average product.Answer:N220 (Option C)
