- Veblen
- C2 (or Comprehensive)
- base

Street vendors operate in the informal cash economy and lack the credit history or collateral required by formal banks.

Which of the following is a mandatory characteristic of a 'Perfectly Competitive' market?
- Firms spend heavily on advertising to differentiate their brands
- There are significant barriers to entry and exit for new firms
- All firms sell perfectly homogeneous (identical) products and are price takers
- A single dominant firm dictates the market price for the entire industry
Answer: All firms sell perfectly homogeneous (identical) products and are price takers
In perfect competition, the market is characterized by a vast number of buyers and sellers trading an identical product (like wheat or copper). Because the products are indistinguishable and there are no barriers to entry, no single firm has any market power to influence the price. They are forced to accept the equilibrium price determined by the aggregate forces of market supply and demand.
The 'Opportunity Cost' of a decision is best defined as:
- The total financial cost incurred to execute the decision
- The value of the next best alternative that is forgone when a choice is made
- The sunk costs that cannot be recovered regardless of the decision
- The accounting profit minus the explicit costs of production
Answer: The value of the next best alternative that is forgone when a choice is made
Opportunity cost is the foundational concept of economics, arising from the reality of scarce resources. It is not the sum of all rejected alternatives, but strictly the value of the single *best* alternative you gave up. For example, if you use a free hour to study instead of working a Rs. 500 shift, the opportunity cost of studying is exactly Rs. 500.
Article ___ of the Indian Constitution strictly mandates that no money shall be withdrawn from the 'Consolidated Fund of India' except under appropriation made by law passed by the Parliament.
- dumping
- 2003
- Governing Council
- 266 (or 266(3))
Answer: 266 (or 266(3))
Article 266 establishes the Consolidated Fund of India, which comprises all government revenues, loans raised, and money received in repayment of loans. Clause (3) of this article is the bedrock of parliamentary democracy and financial control, ensuring that the executive branch cannot spend a single rupee of the public's money without the explicit legislative approval and oversight of the elected representatives.
To avoid the problem of double counting while estimating National Income, economists only consider the value of ___ goods and services, completely ignoring the value of intermediate goods used in the production process.
- final
- India Debt Resolution Company Ltd (IDRCL)
- Mobile
- countervailing
Answer: final
Double counting occurs when the value of raw materials (like wheat) and the final product (like bread) are both added to the GDP, artificially inflating the national income. By strictly counting only 'final' goods—those purchased by the end consumer for direct consumption or investment—the economy accurately captures the total value created without duplicating the costs of intermediate inputs.
The 'PM Gati Shakti' National Master Plan is a digital platform that integrates and coordinates the infrastructure planning and execution of ___ central ministries and state governments to avoid siloed working.
- Unfunded

Historically, infrastructure projects in India suffered from severe delays because ministries worked in silos (e.g., a road being dug up immediately after completion to lay optical fiber cables). Gati Shakti integrates the spatial data and plans of 16 key ministries (including Railways, Roadways, Petroleum, and Telecom) onto a single GIS-based digital platform, ensuring synchronized, multi-modal infrastructure development.

This desperate measure secured a $600 million emergency loan from the IMF, preventing a sovereign default and setting the stage for the historic LPG (Liberalization, Privatization, Globalization) reforms spearheaded by Dr. Manmohan Singh.
