Practice these randomly selected questions to test your readiness.
Question 1
A country's GDP is given by the equation GDP = C + I + G + \( X - M \), where C is consumption, I is investment, G is government sp\ending, X is exports, and M is imports. If the country's GDP is $100 billion, consumption is $50 billion, investment is $20 billion, government sp\ending is $15 billion, exports are $30 billion, and imports are $20 billion, find the value of X.
Question 2
The demand for a product is given by the equation Qd = 100 - 2P, where Qd is the quantity demanded and P is the price. If the price elasticity of demand is 0.5, what is the percentage change in quantity demanded when the price decreases by 10%?
Question 3
A firm's production function is given by the equation Q = 2L^0.5K^0.5, where Q is the quantity produced, L is the number of labor hours, and K is the amount of capital. If the firm's \cost function is given by the equation C = 10L + 20K, what is the firm's profit-maximizing level of labor?
Question 4
A firm's \cost function is given by C(q) = 2q^2 + 10q + 5. If the firm produces 20 units of output, what is the total \cost?
Question 5
A country's GDP grows at an annual rate of 5% while its population grows at an annual rate of 2%. What is the growth rate of per capita GDP?
Question 6
Consider a firm operating in a perfectly competitive market with a production function Q = 2L^0.5K^0.5. If the firm's current input prices are w = 10 and r = 20, and it currently employs 4 units of labor and 2 units of capital, what is the firm's current output level?
Question 7
A firm's demand function is given by the equation Q = 100 - 2P, where Q is the quantity demanded and P is the price. If the firm's supply function is Q = 50 + 3P, find the equilibrium price and quantity.
Question 8
A country's tax revenue is given by the equation TR = T * \( Y - C \), where TR is the tax revenue, T is the tax rate, Y is the national income, and C is consumption. If the country's tax revenue is $50 billion, tax rate is 0.2, national income is $100 billion, and consumption is $50 billion, find the value of T.
Question 9
A firm's production function is given by Q = 2L + 3K. If the firm's labor and capital are ₦200 and ₦300 respectively, what is the firm's output?
Question 10
The money multiplier is a concept in monetary economics that describes the relationship between the money supply and the amount of money in circulation. If the money supply increases by 10% and the reserve requirement is 10%, what is the new money multiplier?
Question 11
A firm's production function is given by the equation Q = 2L^0.5K^0.5, where Q is the quantity produced, L is the number of labor hours, and K is the amount of capital. If the firm's \cost function is given by the equation C = 10L + 20K, what is the firm's profit-maximizing level of capital?
Question 12
A country's demand for a good is given by the demand function Qd = 100 - 2P, where Qd is the quantity demanded and P is the price. The supply function is given by Qs = 2P - 100. What is the equilibrium price and quantity?
Question 13
A consumer's budget constraint is given by the equation IY = 20 - 2Y. If the consumer's income is ₦100, what is the optimal level of consumption?
Question 14
A firm's total revenue (TR) is given by the equation TR = 100x - 2x^2, where x is the number of units sold. If the firm's marginal revenue (MR) is 80, find the value of x.
Question 15
A country's balance of payments is a statistical statement that summarizes all economic transactions between a nation and the rest of the world over a specific period. If a country's current account deficit is $100 billion and its capital account surplus is $50 billion, what is the overall balance of payments deficit?
