(iii) Facilitates infrastructure development: Land is used for building infrastructure like roads, railways, and buildings, which are essential for economic growth. (iv) Generates revenue: Land can generate revenue through taxes, royalties, and rents, which can be used to fund public services and development projects. ================================== (4a) Localization of industries refers to the tendency for firms in the same industry to cluster together in a particular geographic area. This concentration can be driven by various factors such as access to raw materials, skilled labor, markets, specialized infrastructure, or historical development. (4b) -ADVANTAGES- (i)Economic Efficiency and Cost Savings: When industries cluster in a specific geographic area, businesses benefit from reduced transportation costs for raw materials, components, and finished products due to proximity to suppliers and markets. Shared infrastructure, such as utilities, roads, and specialized facilities, further lowers operational expenses. (ii) Knowledge Sharing and Innovation: Localization encourages collaboration among businesses, workers, and research institutions in close proximity. This fosters the exchange of ideas, technical expertise, and best practices, driving innovation and skill development. -DISADVANTAGES- (i) Overcrowding and Environmental Strain: High concentrations of industries can lead to overcrowding, increased traffic, and significant pressure on local resources like water, electricity, and housing. This often results in environmental degradation, such as air and water pollution, which can harm both the ecosystem and residents’ quality of life. (ii) Economic Vulnerability and Dependence: Relying heavily on a single industry or region creates risks if that sector faces a downturn. Economic shocks, such as market declines or technological disruptions, can lead to widespread job losses and economic instability in the area. ================================== (5a) Cash crops are grown for sale in the market to generate income, while food crops are grown primarily for consumption by the farmer and their family.

2025 ONDO STATE JOINT ECONOMICS THEORY ANSWERS ================================== THEORY ANSWER! NUMBER 1 - 8 SOLVED INSTRUCTIONS: Answer One(1) Question from section A and any other Three(3) questions from section B. All questions carry equal marks. ================================== SECTION A (Answer Any One(1) Question from this Section. (1a) TABULATE Given Incomes (20 teachers): Income (₦): 30, 20, 80, 40, 20, 40, 40, 70, 50, 50, 20, 30, 40, 20, 20, 40, 60, 60, 70, 80 (i) Mean Income Step 1: Add all incomes: = 20×5 + 30×2 + 40×5 + 50×2 + 60×2 + 70×2 + 80×2 = (20×5=100) + (30×2=60) + (40×5=200) + (50×2=100) + (60×2=120) + (70×2=140) + (80×2=160) = 100 + 60 + 200 + 100 + 120 + 140 + 160 = 880 Mean = Total Income / Number of teachers = 880 / 20 = ₦44.00 (ii) Modal Income (most frequent) ₦20 and ₦40 both appear 5 times each, so the data is bimodal. Modal Income = ₦20 and ₦40 (iii) Median Income (middle value in ordered list) Since there are 20 teachers (even number), median is the average of the 10th and 11th values. Ordered incomes: 20, 20, 20, 20, 20, 30, 30, 40, 40, *40*, *40*, 40, 50, 50, 60, 60, 70, 70, 80, 80 10th = 40, 11th = 40 Median = (40 + 40) / 2 = ₦40 (1b) Range of Income Distribution: Highest income = 80, Lowest = 20 Range = 80 - 20 = ₦60 (1c) TAX CALCULATIONS (i) Flat rate of 7% on all teachers Tax = 7% of 880 = 0.07 × 880 = ₦61.60 (ii) Flat rate of 15% on income ≥ ₦40 Teachers earning ₦40 and above, ₦40 (5 teachers), ₦50 (2), ₦60 (2), ₦70 (2), ₦80 (2) = 13 teachers. Total income from these = 200 + 100 + 120 + 140 + 160 = ₦720 Tax = 15% of 720 = 0.15 × 720 = ₦108.00 ================================== (2a) Given: Demand function: Qd = 30 - P Supply function: Qs = 15 + 2P PLEASE TABULATE | Price (₦) | Demand Qd = 30 - P | Supply Qs = 15 + 2P | |-----------|--------------------|---------------------| | 2 | 30 - 2 = 28 | 15 + 4 = 19 | | 4 | 30 - 4 = 26 | 15 + 8 = 23 | | 7 | 30 - 7 = 23 | 15 + 14 = 29 | (2b) Set demand equal to supply for equilibrium: 30 - P = 15 + 2P 30 - 15 = 2P + P 15 = 3P P = 5 (Equilibrium price) Substitute P = 5 to find quantity Qd = 30 - 5 = 25 Qs = 15 + 2(5) = 15 + 10 = 25 units (2c) Calculate Qd and Qs at P = ₦3: Qd = 30 - 3 = 27 Qs = 15 + 2(3) = 15 + 6 = 21 Excess demand = Qd - Qs = 27 - 21 = 6 units So, there will be an excess demand of 6 textbooks. (2d) (i) (TABULATE) | Price (₦) | New Demand Qd = 40 - P | |-----------|------------------------| | 2 | 40 - 2 = 38 | | 4 | 40 - 4 = 36 | | 7 | 40 - 7 = 33 | (ii) It represents an increase in demand because at each price, the quantity demanded is higher than before. (iii) The new demand function shifts demand to the right, meaning consumers want to buy more textbooks at each price level than before. This could be due to factors like increased preference, income or changes in tastes. ================================== SECTION B Answer Any Three(3) Questions from this Section. (3a) Land is a primary factor of production, encompassing all natural resources used in the production process. This includes the earth's surface, natural resources found on or under it (like minerals, water, and forests), and anything permanently attached to it. (3b) (i) It is a free gift of nature. (ii) It has a fixed supply. (iii) It is immobile. (iv) It is subject to diminishing returns. (3c) (i) Provides resources for production: Land provides essential resources like minerals, timber, and agricultural land, which are crucial for various industries and economic activities. (ii) Supports agriculture: Land is the foundation for agriculture, which provides food, employment, and raw materials for industries.
