Practice these randomly selected questions to test your readiness.
Question 1
A country's national income is given by the following equation: \( NI = C + I + G + \( X - M \ \)). If the country's consumption is ₦120 billion, investment is ₦80 billion, government sp\ending is ₦60 billion, exports are ₦100 billion, and imports are ₦80 billion, what is the country's national income?
Question 2
A consumer has a utility function U(x,y) = 2x + 3y. If the prices of x and y are ₦10 and ₦20 respectively, and the consumer's budget is ₦100, what is the optimal bundle of x and y?
Question 3
Determine the value of the elasticity of demand for a firm that experiences a 10% increase in price, resulting in a 5% decrease in quantity demanded.
Question 4
A monopolist faces a demand curve given by Q = 100 - 2P and a \cost function C(Q) = 2Q^2 + 10Q. If the firm's marginal revenue is MR = 50 - 2Q, what is the optimal quantity to produce?
Question 5
A firm is operating in a perfectly competitive market with a production function given by Q = 3L^0.5K^0.5. If the firm's current input prices are w_L = 15 and w_K = 30, and it wishes to maximize its profit, what is the optimal level of capital (K) it should employ, given that the market price of its output is P = 60?
Question 6
A firm's demand function is given by Q = 100 - 2P, where Q is quantity demanded and P is price. If the firm's price is ₦50, what is the quantity demanded?
Question 7
A country's GDP is ₦1,500 billion, and its GNP is ₦1,600 billion. What is the net factor income from abroad?
Question 8
A country's balance of payments is given by the following equation: BOP = \( X - M \) + \( F - I \). If the country's exports are ₦500 billion, its imports are ₦600 billion, its foreign investment is ₦200 billion, and its domestic investment is ₦300 billion, what is the balance of payments?
Question 9
A country's agricultural sector is given by the following production function: Q = 100L^0.5K^0.5, where Q is output, L is labor and K is capital. If the country's labor and capital are 100 units each, what is the marginal product of labor?
Question 10
A firm's production function is given by Q = 2L^0.5K^0.5, where Q is output, L is labor, and K is capital. If the firm's marginal product of labor (MPL) is 1/L^0.5K^0.5, what is the value of MPL when L = 4 and K = 9?
Question 11
A country's balance of payments is given by the following equation: BOP = X - M - \( I - S \). If the country's exports (X) are ₦100 billion, imports (M) are ₦80 billion, investment (I) is ₦50 billion and savings (S) is ₦30 billion, what is the balance of payments?
Question 12
A firm's production function is given by Q = 100L^0.5K^0.5, where Q is output, L is labor and K is capital. If the firm's labor and capital are 100 units each, what is the marginal product of labor?
Question 13
A country's GDP is calculated u\sing the following formula: \( GDP = C + I + G + \( X - M \ \)). If the country's consumption is ₦120 billion, investment is ₦80 billion, government sp\ending is ₦60 billion, exports are ₦100 billion, and imports are ₦80 billion, what is the country's GDP?
Question 14
A firm's revenue function is given by R = 100Q - 2Q^2, where R is revenue and Q is quantity sold. If the firm sells 50 units, what is the revenue?
Question 15
A firm's total revenue (TR) is given by the equation TR = 20q + 30q^2, where q is the quantity sold. If the firm's marginal revenue (MR) is 40q + 60q^2, what is the value of q when MR = TR?
