Practice these randomly selected questions to test your readiness.
Question 1
The demand function for a product is given by \( Q = 100 - 2P \). If the supply function is \( Q = 2P - 10 \), find the equilibrium price and quantity.
Question 2
A country's GDP is given by GDP = 1000 + 2Y + 0.5Y^2, where Y is the country's income. If the country's GNP is given by GNP = 1200 + 3Y + 0.75Y^2, find the country's GDP and GNP when Y = 100.
Question 3
A consumer's utility function is given by U = 2x + 3y. If the consumer's current budget is ₦100 and the prices of good x and good y are ₦5 and ₦10 respectively, what is the consumer's optimal bundle of goods?
Question 4
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 increases by 10%?
Question 5
A firm's demand function is given by Q = 100 - 2P. If the firm's current price (P) is ₦20, what is the firm's current level of demand (Q)?
Question 6
A firm's demand function is given by \( Q = 100 - 2P \). If the firm's supply function is \( Q = 2P - 10 \), find the firm's profit-maximizing price and quantity.
Question 7
A country has a budget deficit of 5% of its GDP and a GDP growth rate of 5%. If the country's inflation rate is 2%, what is the percentage change in the value of the government's debt?
Question 8
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 9
A firm has a production function given by Q = 2L^0.5K^0.5, where Q is the output, L is the labor, and K is the capital. If the firm has 4 units of labor and 9 units of capital, what is the marginal product of labor?
Question 10
A country's GDP is given by GDP = 1500 + 3Y + 0.75Y^2, where Y is the country's income. If the country's GNP is given by GNP = 1800 + 4Y + 0.9Y^2, find the country's GDP and GNP when Y = 150.
Question 11
A consumer's indifference curve is given by the equation ( U(x,y) = 2x + 3y ). If the consumer's income is ₦1000 and the prices of x and y are ₦5 and ₦3 respectively, find the consumer's optimal bundle of x and y.
Question 12
A consumer's utility function is given by U = 2x + 3y. If the consumer's income is ₦100, and the prices of x and y are ₦5 and ₦10 respectively, what is the optimal bundle of x and y?
Question 13
A country's GDP is given by the equation GDP = C + I + G + \( X - M \). If the country's current level of consumption (C) is ₦100 billion, the current level of investment (I) is ₦50 billion, the current level of government sp\ending (G) is ₦75 billion, the current level of exports (X) is ₦200 billion, and the current level of imports (M) is ₦150 billion, what is the country's current GDP?
Question 14
A country's GDP is given by \( GDP = C + I + G + \( X - M \ \) ). If the country's consumption is ₦500 billion, investment is ₦200 billion, government exp\enditure is ₦300 billion, exports are ₦400 billion, and imports are ₦200 billion, find the country's GDP.
Question 15
A firm's production function is given by Q = 100K^\( 1/2 \)L^\( 1/2 \). If the firm increases the capital from 100 to 400, and the labor from 100 to 400, what is the percentage change in output?
