POST UTME GREENFIELD UNIVERSITY 2023 Economics | Objective
Practice these randomly selected questions to test your readiness.
Question 1
A monopolist faces a demand curve given by \( Q = 100 - 2P \) and a marginal revenue curve given by \( MR = 20 - 2Q \). What is the profit-maximizing quantity?
Question 2
A country's GDP is calculated as the sum of the value of all final goods and services produced within its borders. However, this calculation does not include the value of:
Question 3
The government of a country wants to increase its GDP by 10% in a year. If the current GDP is ₦10 trillion, what is the amount of additional investment needed to achieve this goal?
Question 4
A firm is considering two different production techno\logies: one that requires 2 units of labor and 1 unit of capital to produce 1 unit of output, and another that requires 1 unit of labor and 2 units of capital to produce 1 unit of output. If the firm wants to produce 100 units of output, which techno\logy should it choose?
Question 5
The production function is given by Q = 2L^0.5K^0.5. If the price of labor \( P_L \) is ₦100 and the price of capital \( P_K \) is ₦200, calculate the opportunity \cost of labor in terms of capital.
Question 6
Consider a perfectly competitive market with n firms, each producing a homogeneous product. If the market price is $P = 10, and the inverse demand function is given by P = 100 - 2Q, where Q is the total quantity demanded, what is the marginal revenue (MR) function?
Question 7
A government in Nigeria imposes a tax on sugar of 10% ad valorem. If the price of sugar is $1 per ki\logram, what is the tax revenue collected from selling 1000 ki\lograms of sugar?
Question 8
Consider a firm operating in a perfectly competitive market with a production function Q = 2L^0.5K^0.5. If the price of the good is P = 10, and the firm's \cost function is C = 2L + 3K, what is the firm's profit-maximizing level of output?
Question 9
A firm has a \cost function given by C = 100 + 2Q, where C is the total \cost and Q is the quantity produced. If the firm produces 50 units of the good, what is its total revenue?
Question 10
A consumer has a budget of ₦1000 and faces a price of ₦200 for a good. If the consumer's indifference curve is given by the equation U = 2x + 3y, where x is the quantity of the good consumed and y is the quantity of a complementary good, what is the optimal quantity of the good consumed?
Question 11
A monopolist faces a demand curve given by Q = 100 - 2P. If the marginal \cost (MC) is $5, what is the profit-maximizing quantity?
Question 12
The scarcity of a particular good in a market can be attributed to the following factors EXCEPT:
Question 13
In a perfectly competitive market, the demand curve for a firm's product is its
Question 14
The demand function for a product is given by Q = 100 - 2P. The supply function is given by Q = 2P - 50. Find the equilibrium price and quantity.
Question 15
A country's demand for a good is given by the demand function Q = 100 - 2P, where Q is the quantity demanded and P is the price. If the supply function is given by Q = 2P + 50, what is the equilibrium price?
