HCS 2024 Prelims — Solved Using the Sherlocking Method
Every question from the HCS 2024 Prelims paper, analysed with Sherlocking Insights — showing you exactly how logical elimination, pattern recognition, and common-sense reasoning can crack questions you don't fully know the answer to.
Watch: The Complete Sherlocking Strategy for State PCS Prelims
Neil Sir breaks down the 4-phase strategy: building foundations with NCERTs & PYQs, developing an application-oriented mindset, the paper-attempt strategy for maximising attempts (target 80–90 questions), and understanding the optimisation math behind clearing cut-offs.
What's Inside This PDF
Complete HCS 2024 Prelims GS paper
Correct answers for every question
Sherlocking Insight for each question
Logical elimination walkthroughs
Topics covered span the full UPSC & State PCS GS syllabus: Economics (PLFS, Gini Index, RoDTEP), Indian Polity (Fugitive Economic Offenders Act, PCA Framework), Geography (soils — Regur, red-yellow, laterite; rivers, minerals, ports), Science (solar system, fertilizers), Environment (species conservation, grasslands), History (1857 revolt, mountain passes), and more. Each question's Sherlocking Insight shows which statements are traps, how to eliminate options systematically, and the reasoning behind every answer.
Sample Questions with Sherlocking Insights
Here's a preview of how the Sherlocking method is applied to actual HCS 2024 questions. The full PDF contains insights for every question.
Q13. Which of the following features are associated with Regur Soils in India?
- It develops on crystalline igneous rocks as a result of intense leaching.
- It is rich in Iron, Potash and Phosphoric contents.
- It is typically found in north-west region of Deccan plateau and made up of lava flows.
- It is rich in calcium carbonate, magnesium, potash and lime.
How many of the statements given above are correct?
(A) 1 and 2 only (B) 2 and 3 only (C) 3 and 4 only (D) 1, 2 and 4 only
Answer: C (3 and 4 only)
Sherlocking Insight
S1: Regur forms from basaltic lava flows (Deccan Trap), not from crystalline igneous rocks via leaching. "Intense leaching" is a red-soil formation process. Two wrong hooks in one statement.
S2: Regur is poor in phosphorus, nitrogen, and organic matter. The "phosphoric" claim is the trap.
S3: Deccan plateau + lava flows is the classic Regur pairing.
S4: Calcium carbonate, magnesium, lime is familiar Regur chemistry.
S1 out cuts A (1 and 2) and D (1, 2 and 4). S2's phosphorus trap cuts B (2 and 3). Leaves C (3 and 4).
Q18. Consider the following statements:
- Copper, Lead, Tin and Bauxite are non-ferrous minerals.
- Manganese, Iron, Cobalt and Mica are ferrous minerals.
- Potash, Marble and Granite are non-metallic minerals.
- Nickel, Cobalt and Platinum are precious metals.
(A) 1 and 3 only (B) 1 and 4 only (C) 2 and 3 only (D) 2, 3 and 4 only
Answer: A (1 and 3 only)
Sherlocking Insight
S1: Copper, Lead, Tin, Bauxite are classic non-ferrous minerals.
S2: "Mica" is the trap. Mica is a non-metallic mineral, not ferrous. Ferrous = iron-containing.
S3: Potash, Marble, Granite are all non-metallic, familiar classification.
S4: Nickel and Cobalt are base or strategic metals, not precious. Only Platinum qualifies as precious in that list.
S2 wrong cuts C (2 and 3) and D (2, 3, 4). S4 wrong cuts B (1 and 4) and D (already gone). Leaves A (1 and 3).
These are just 2 of the many questions in the full PDF — each with its own Sherlocking Insight.

Phase 1
Building a Solid Foundation
Master basic sources — NCERTs, Laxmikanth, Spectrum. The commission creates papers directly from these foundational resources. Analyse PYQs for both HCS and UPSC to identify recurring patterns.
Phase 2
Developing an Application-Oriented Mindset
Apply logical reasoning (Sherlocking) when questions fall outside your basic sources. Look for hints within the question itself. Accept "dignified negatives" — calculated guesses when you can narrow down to 50-50 odds.
Phase 3
The Paper-Attempt Strategy
Don't rely solely on direct knowledge (that limits you to 20–30 questions). Use Sherlocking to maximise attempts — target 80–90 questions. Go through the paper in 2–3 iterations. Skip only the ~10 questions that defy both your sources and logic.
Phase 4
The Optimisation Math
Don't aim for a perfect score. If you attempt 85 questions and get 55 correct with 30 incorrect, your net score clears the cut-off (roughly 40–45 marks for HCS 2024). Balance attempts with accuracy — that's the real strategy.
How Does the Sherlocking Method Work?
The Sherlocking method is built on three pillars: logical elimination (identify and discard wrong options using basic knowledge), pattern mastery (recognise recurring question structures that UPSC and State Commissions reuse), and common-sense reasoning (use real-world logic when factual recall falls short).
Together, these skills turn partial knowledge into correct answers. This PDF demonstrates all three on a real exam paper — making it the perfect practice resource.

Frequently Asked Questions
What is the Sherlocking Method used in this HCS 2024 solved paper?
The Sherlocking Method is a strategic framework developed by UnlockIAS that uses pattern recognition, logical elimination, and common-sense reasoning to solve MCQs — even when you don't know the exact answer. In this solved paper, every HCS 2024 Prelims question includes a "Sherlocking Insight" box that walks you through how to eliminate wrong options using logic, identify UPSC-style traps, and arrive at the correct answer through deduction rather than pure memorisation.
How many questions are solved in this PDF?
The PDF covers the complete HCS 2024 Prelims General Studies paper. Each question includes the correct answer and a detailed Sherlocking Insight that explains the logical elimination process — which statements are traps, which options get eliminated, and how to arrive at the answer even with partial knowledge.
Is the Sherlocking Method useful only for HCS or does it work for UPSC CSE too?
The Sherlocking Method was originally developed for UPSC CSE Prelims and has been proven across multiple State PCS exams including HCS, BPSC, UPPSC, OPSC, JKPSC, and RAS. State commissions frequently model their papers on UPSC patterns, so the same logical elimination and pattern recognition techniques work across all these exams. This HCS 2024 paper is an excellent example of how the method applies to State PCS.
Who prepared this solved paper?
This solved paper was prepared by the UnlockIAS team, led by Neil Sir (Founder, HCS 2021). The Sherlocking Insights are based on the same methodology that is integrated into the UnlockIAS test series and Sherlocking Prelims Module, which has helped students secure top ranks in UPSC CSE, HCS, BPSC, JKPSC, and other competitive exams.
Can I share this PDF with friends preparing for HCS or other exams?
Absolutely — this resource is free to download and share. We encourage you to share it with anyone preparing for HCS, UPSC, or any State PCS exam. The more aspirants understand the Sherlocking approach, the better prepared the community becomes.
