D. The demand curve is inelastic
Question 10
A government is considering implementing a policy to reduce income inequality. U\sing the concept of Lorenz curve, determine the Gini coefficient of income distribution in a country with the following income distribution: 20% of the population has an income of $10,000, 30% has an income of $20,000, 20% has an income of $30,000, and 30% has an income of $40,000.
A. 0.2
B. 0.3

B. 30 units
C. 40 units
D. 50 units
Question 12
A country's balance of payments is given by the following equation: BOP = X - M - \( I - S \), where X is exports, M is imports, I is investment, and S is savings. If the country's exports are ₦100 billion, imports are ₦80 billion, investment is ₦50 billion, and savings are ₦30 billion, what is the balance of payments?
