Topics in Logical Deduction
1
Understanding the Five Verdict Categories
- Each inference must be evaluated solely on the basis of the passage — no external knowledge should influence your verdict.
- Definitely True (DT): The inference logically and necessarily follows from the facts stated. No room for doubt.
- Probably True (PT): The inference is likely to be true given the facts, but it is not explicitly confirmed. It is a reasonable extrapolation.
2
Decision Framework: How to Evaluate Each Inference
- Step 1 — Read the passage completely and identify the key factual claims.
- Step 2 — Read the inference carefully, noting its scope (all/some/none), direction (positive/negative), and subject.
- Step 3 — Check if the passage directly states the inference (DT) or directly contradicts it (DF).

Analysing Passage Types and Common Inference Patterns
- Passages in Logical Deduction typically belong to categories: Economic/Financial, Social/Political, Scientific/Technological, or Historical/Cultural.
- Economic passages often contain statistics, comparisons, and trend data — inferences about causation, future trends, and comparisons with unmentioned entities are frequently DI.
- Scientific/Technological passages often generate inferences about applicability, advantages, and comparisons with competing technologies — these are often PT or DI.
4
Worked Examples and Verdict Justification
- Passage-1 Example: 'India has emerged as an IT superpower' (given fact). Inference: 'India can compete with US in IT' — the passage gives no information about the US IT sector; hence DI, not DT.
- Passage-1 Example: 'Hire and Fire culture was introduced into corporations after economic reform' is an inference that slightly extends the passage. Since the passage only says it 'infiltrated', it do
- Passage-2 Example: 'FIIs net inflows = Rs 3187 crore; domestic institutions net sales = Rs 2964 crore; net sales substantially offset net inflows' — the inference that FIIs bought more than what domes
