Revision summary
The 2015 revision moved the base from 2004-05 to 2011-12 and replaced GDP at factor cost with GVA at basic prices. Headline GDP is at market prices, in line with SNA 2008. MCA21 and wider financial and local-body coverage changed what enters the total. New IIP and price deflators mean the series is not a relabelled old index. Debate on comparability is fair; a conspiracy reading is not.

Copper italics in this answer — like this — are the key facts. Each one is unpacked in the Facts & figures rail.
Introduction
In January 2015 India shifted the National Accounts to a 2011-12 base and to System of National Accounts 2008 ideas. The change was about what is counted, at which prices, and from which books, not a secret rewrite of real output.
Body
What changed in the headline
- Before 2015 the familiar production measure was GDP at factor cost on a 2004-05 base. After 2015 the production measure is Gross Value Added (GVA) at basic prices on a 2011-12 base.
- Basic prices add production taxes and subtract production subsidies from factor-cost GVA. They are not the same as factor cost.
- Headline GDP is now stated at market prices: GVA plus product taxes minus product subsidies. That matches how most countries quote GDP.
- New series numbers cannot be read as a simple markup of the old series. The basket, the base, and the books all moved together.
Data books and coverage
- The corporate sector moved toward MCA21 company filings instead of relying mainly on the Index of Industrial Production and a thinner set of company accounts.
- Coverage widened for financial corporations, local bodies, and autonomous institutions, which the old series under-counted.
- Informal and unorganised activity still uses survey labour input and value added per worker, but with newer NSS and enterprise frames rather than a frozen 2004-05 picture.
- Deflators shifted with new IIP, WPI, and CPI series, so real growth is not the old volume index with a new label.
How to read the debate
- Growth rates jumped in some years because the new books captured more organised activity, not because output was invented in a back room.
- Comparability with 2004-05 is imperfect. That is a fair statistical complaint. It is not evidence of a political conspiracy.
- Users should quote GVA at basic prices and GDP at market prices correctly, and never say India still publishes GDP at factor cost as the main production total.

Conclusion
After 2015 India measures production as GVA at basic prices on a 2011-12 base, with MCA21 and wider coverage, and quotes GDP at market prices. The revision aligned books with SNA 2008. It changed the ruler; it did not secretly reprint the cloth.

-
Is GVA at basic prices the same as GDP at factor cost?
No. Basic prices include production taxes net of production subsidies. Factor cost does not.
-
Did the 2015 series invent higher growth?
It counted organised activity from better books and a new base. Levels and rates are not strictly comparable with 2004-05, which is a method issue, not a conspiracy.

What are the challenges to solid waste management in India? Discuss the governmental policy framework on solid waste management. Discuss the success/failure cases of Delhi and Indore cities highlighting the salient features of their solid waste management initiatives.
Indian Economy
• Rapid urbanization has made solid waste management a critical environmental and public health crisis in India. • Key challenges include lack of source segregation, inadequate processing infrastructure, reliance on unprotected informal workers, and financially weak urban local bodies. • The policy framework relies on the SWM Rules 2016, Swachh Bharat Mission (Urban), and Plastic Waste Management Rules 2016. • Indore succeeded through 100% source segregation, zero dump-site remediation, and strict enforcement with digital monitoring. • Delhi failed due to overloaded legacy landfills (Ghazipur, Bhalswa), lack of decentralization, and fragmented municipal governance. • A successful transition requires moving to a circular economy focused on source segregation, decentralized processing, and polluter accountability.

What is Agentic Artificial Intelligence (AI)? Explain its working. Describe its applications with suitable examples. Discuss the advantages, risks and challenges associated with agentic AI systems.
Indian Economy
Agentic Artificial Intelligence represents an advanced paradigm where AI systems operate with autonomy, setting goals and executing complex workflows without constant human prompts. Unlike traditional generative AI that merely responds to queries, agentic AI uses perception, planning, memory, and tool-use to achieve multi-step objectives. Its applications span across autonomous software engineering, supply chain optimization, and automated financial trading. While offering massive productivity gains and dynamic problem-solving, these systems pose significant risks including lack of transparency, alignment failures, security vulnerabilities, and ethical dilemmas. Governance frameworks and robust guardrails are essential to harness their potential safely.
