Practice these randomly selected questions to test your readiness.
Question 1
A firm's demand function is given by D(p) = 100 - 2p, where p is the price of the good. If the firm's supply function is S(p) = 2p + 5, find the equilibrium price and quantity.
Question 2
A firm produces two goods, X and Y. The production function for good X is given by Q_X = 2L + 3K, where L is the labor input and K is the capital input. The production function for good Y is given by Q_Y = 3L + 2K. If the firm has 10 units of labor and 8 units of capital, what is the opportunity \cost of producing one more unit of good X?
Question 3
A firm's total revenue is given by the equation \( TR = 2x^2 + 5x \). If the firm's marginal revenue is ₦10, find the firm's optimal output.
Question 4
The balance of payments (BOP) accounts for a country are given below. U\sing the BOP identity, calculate the current account balance.
Question 5
A consumer's utility function is given by U = 2x + 3y. If the consumer's income is ₦1000 and the prices of x and y are ₦2 and ₦3 respectively, calculate the consumer's optimal bundle of x and y.
Question 6
A central bank's money supply is given by the equation \( MS = C + D + \( B - R \ \) ). If the central bank's currency in circulation is ₦500 billion, deposits are ₦200 billion, and reserve requirements are ₦100 billion, find the central bank's money supply.
Question 7
A consumer has a budget of ₦1000 and faces the following prices for two goods: good X \costs ₦200 per unit and good Y \costs ₦300 per unit. The consumer's utility function is given by U = 2X + 3Y. What is the consumer's optimal consumption bundle?
Question 8
A country is experiencing a trade deficit, and the government decides to implement a trade policy to reduce the deficit. If the country imports $100 billion worth of goods and services and the exchange rate is 1 USD = 1.5 NGN, what is the value of the trade deficit in NGN?
Question 9
A monopolist faces a demand curve given by Q = 100 - 2P and a \cost function C(Q) = 2Q^2 + 10Q. Find the profit-maximizing price and quantity.
Question 10
A firm's production function is given by Q = 2L + 3K, where Q is the output, L is the labor, and K is the capital. If the labor is 10 units and the capital is 5 units, what is the output?
Question 11
The GDP of a country is given by the equation \( GDP = C + I + G + \( X - M \ \) ). If the country's consumption is ₦500 billion, investment is ₦200 billion, government sp\ending is ₦300 billion, exports are ₦400 billion, and imports are ₦200 billion, find the country's GDP.
Question 12
A firm is producing a good with a production function of Q = 2L + 3K, where L is labor and K is capital. If the wage rate is $20 per hour and the rental rate of capital is $10 per hour, what is the marginal product of labor?
Question 13
A country's money supply is given by the equation: M = \( C + I \) + \( B - L \), where C is consumption, I is investment, B is bank reserves, and L is loans. If C = 100, I = 80, B = 120, and L = 90, what is the money supply?
Question 14
A consumer has a utility function given by U = 2X + 3Y, where X and Y are the quantities of two goods consumed. The consumer's budget constraint is given by 2X + 3Y = 100. What is the consumer's optimal consumption bundle?
Question 15
A country's balance of payments is given by Exports = ₦1000, Imports = ₦800, and Net Factor Income = ₦200. Calculate the country's current account balance.
