**Economics** = management of limited resources to satisfy unlimited wants (from Greek: oikos = household, nemein = manage).
**Key Definitions:**
• **Needs** = essentials (food, water, shelter)
• **Wants** = optional preferences that change (gadgets, vacations)
• **Resources** = land, labour, capital, technology used for production
• **Opportunity Cost** = value of next best alternative given up
• **PPC (Production Possibility Curve)** = shows max output with efficient resource use
• **Economic Survey** = annual report on India's economy; guides Union Budget
**The Problem of Choice:** Every individual, enterprise, and government must decide how to allocate scarce resources among competing uses.
**PPC Key Point:** Points ON the curve = maximum efficiency; points BELOW = wastage; points ABOVE = impossible with current resources.
**Economic Entities:** Consumers, producers, governments, and financial institutions interact in economy through buying, selling, earning wages, and policy decisions.
Q1. Which of the following is an example of a 'need' rather than a 'want'?
Answer: C — Safe drinking water is an essential for survival, whereas smartphones, vacations, and jewellery are optional preferences classified as wants.
Q2. What does the Production Possibility Curve (PPC) primarily represent?
Answer: B — The PPC shows all possible combinations of two goods that can be produced at maximum efficiency without wasting resources.
Q3. If a farmer has land that can grow either rice or cotton, and chooses to grow rice, what is the opportunity cost?
Answer: B — Opportunity cost is the value of the next best alternative sacrificed; here, growing rice means giving up the cotton that could have been produced.
Q4. The Economic Survey of India is prepared by which ministry and presented before which body?
Answer: B — The Economic Survey is prepared by the Ministry of Finance and presented in Parliament before the Union Budget each year.
Q5. Which of the following statements about resources is NOT correct?
Answer: B — Resources are actually limited in quantity and cannot satisfy all unlimited human wants, which creates the fundamental economic problem of choice.
Q6. Ramesh's family has Rs. 5000 per month. They must choose between spending on food, education, or buying a television. What economic principle does this situation illustrate?
Answer: B — The situation shows how limited income forces a household to choose between alternative uses, demonstrating the fundamental economic problem of scarcity.
Q7. A point on the Production Possibility Curve indicates which of the following?
Answer: B — Any point ON the PPC represents the maximum possible output when all resources are used efficiently without wastage.
Q8. Which statement correctly describes the relationship between needs, wants, and economic choice?
Answer: B — Needs are essential and stable, but wants are unlimited and constantly changing, which forces individuals and economies to make difficult choices on resource allocation.
Q9. The four factors of production (land, labour, capital, technology) are considered 'limited' because:
Answer: B — Factors of production are limited because they exist in finite quantities and can be allocated to many different uses, requiring economic choices.
Q10. Which of the following is a primary function of the Economic Survey in India's economic planning?
Answer: B — The Economic Survey acts as a comprehensive annual review and analysis that helps policymakers and the government understand performance and plan future economic strategies.
What does the word 'Economics' mean etymologically?
Economics comes from Greek 'oikonomia'—oikos (household) + nemein (management)—referring to household management of limited resources.
Define opportunity cost with one example.
Opportunity cost is the value of the next best alternative given up when making a choice; for example, if a farmer grows barley, the wheat sacrificed is the opportunity cost.
What is the difference between needs and wants?
Needs are essentials like food, water, and shelter; wants are optional preferences like gadgets, vacations, and luxury items that change over time.
What does a Production Possibility Curve (PPC) show?
A PPC shows different combinations of two goods that can be produced using all available resources efficiently without wastage.
Why are resources called 'limited' or 'scarce'?
Resources are limited in quantity because they can be put to many alternative uses, and there are not enough to satisfy all unlimited human wants.
Name four factors of production.
The four factors of production are land, labour, capital, and technology.
What does the Economic Survey of India do?
The Economic Survey is an annual government report that reviews India's economic performance, analyses various sectors, and guides the Union Budget and policy decisions.
What does a point below the PPC curve indicate?
A point below the PPC curve indicates inefficient use of resources and wastage, meaning the economy is not producing at its maximum capacity.
Give an example of how households make economic choices.
Households allocate money between essentials (food, medicines), non-essentials (entertainment), and savings based on their limited income and priorities.
Why do economists use data and analysis?
Economists use data and analysis to understand available alternatives, opportunity costs, and potential outcomes so that individuals, enterprises, and institutions can make informed decisions rather than guesses.
Define the term 'opportunity cost' and provide one everyday example from a teenager's life. [2 marks]
Opportunity cost is the value of the next best alternative given up when choosing one option. Example: if you choose to buy a book, the snack you could have bought is the opportunity cost.
Explain why the Production Possibility Curve (PPC) is a downward-sloping curve. What does a point below the PPC curve indicate about an economy? [3 marks]
PPC slopes downward because producing more of one good requires sacrificing another (trade-off). A point below the curve means resources are being wasted and the economy is not operating at full efficiency.
The government of a country must decide whether to spend its limited budget on building new highways or new hospitals. Using the concept of opportunity cost and the Production Possibility Curve, explain how this decision affects the economy and its people. What data and analysis would help the government make a better choice? [5 marks]
Discuss opportunity cost of choosing highways over hospitals. Explain using PPC how this choice shows trade-off between two goods. Mention role of Economic Survey, data analysis, and how such decisions affect employment, health, and development.
