Statements, Assumptions & Conclusions: Aptitude Test Guide

Statements, assumptions, conclusions, and courses of action form one of the most reliably tested logical reasoning clusters in TCS NQT, Infosys, and other campus placement tests.

Three distinct question types fall under this heading, and each needs its own decision rule. Treating a conclusion as if it were an assumption, or a course of action as if it were a conclusion, is the most common source of dropped marks in this section.

The Three Question Types

Question type	What it asks	Key decision rule
Statements and Assumptions	Is this unstated belief implicit in the statement?	Negate it; if the argument collapses, it is implicit
Statements and Conclusions	Does this inference follow directly from the statement?	A valid conclusion extracts what is already there; it adds nothing new
Statements and Courses of Action	Is this a practical response to the stated problem?	Valid if it directly addresses the issue, is feasible, and is proportionate

Both TCS and Infosys include logical reasoning in their fresher hiring process. The TCS National Qualifier Test includes a verbal ability section where critical reasoning questions appear alongside reading comprehension. The Infosys InfyTQ platform similarly tests logical reasoning during campus and off-campus drives.

Several other companies test this skill set in their aptitude rounds. Sopra Steria’s online test includes verbal and logical reasoning (see the Sopra Steria recruitment guide for the full test structure). Philips includes an analytical ability section in its recruitment rounds (see the Philips recruitment guide for details).

Statements and Assumptions

An assumption is an unstated belief that the speaker or writer takes for granted when making a statement. It is something that must be true for the statement to make logical sense, but it is never said explicitly.

The decision rule

To check whether a proposed assumption is implicit:

1. Negate the assumption (treat it as false).
2. Ask whether the original statement still holds.
3. If the statement collapses or becomes meaningless, the assumption is implicit. If the statement survives, it is not.

Worked examples

• Example 1

  • Statement: Since it is raining, the cricket match will be postponed.
  • Assumption I: Rain causes cricket matches to be postponed.
  • Assumption II: A cricket match was scheduled for today.
  • Answer: Both I and II are implicit.
  • Why: Negate I (“Rain does not cause matches to be postponed”) and the postponement has no basis. Negate II (“No match was scheduled today”) and the statement has no subject. Both hold under the negation test.

• Example 2

  • Statement: The health department advised citizens to drink at least 8 glasses of water daily.
  • Assumption I: Drinking 8 glasses of water per day is beneficial for health.
  • Assumption II: Citizens currently drink fewer than 8 glasses per day.
  • Answer: Both I and II are implicit.
  • Why: Health advice is only issued for beneficial actions (I). Advising someone to increase intake assumes the current level is insufficient (II).

• Example 3

  • Statement: To clear TCS NQT, practice at least 30 mock tests before the exam.
  • Assumption I: Mock tests are the most effective preparation method for TCS NQT.
  • Assumption II: TCS NQT performance improves with practice.
  • Answer: II is implicit. I is NOT implicit.
  • Why: The advice to practice assumes practice helps (II). But “practice mock tests” does not mean mock tests are the single most effective method — that claim extends beyond what the statement requires. Accepting Assumption I is the classic extension fallacy: the assumption goes further than the statement needs it to.

• Example 4

  • Statement: Only engineers with a CGPA above 7.0 may apply for the campus placement drive.
  • Assumption I: Some engineers have a CGPA above 7.0.
  • Assumption II: CGPA is a meaningful measure of candidate quality.
  • Answer: Both I and II are implicit.
  • Why: A threshold rule only makes sense if some candidates can actually meet it (I). Using CGPA as a filter assumes the organisation considers it a meaningful criterion (II).

Statements and Conclusions

A conclusion is a logical inference drawn directly from the statement. It does not add new information. It only unpacks what the statement already contains.

The trap most test-takers fall into is accepting a conclusion that seems plausible rather than one that logically follows. Plausibility is not the test. The question is whether the conclusion can be derived from the statement without adding anything from outside.

The decision rule

A conclusion is valid when:

• It follows directly from the statement without requiring additional assumptions.
• It does not use stronger quantifiers than the statement supports (“all” where the statement says “most”; “never” where the statement says “rarely”).
• It does not make claims about topics or scopes the statement does not address.

Worked examples

• Example 5

  • Statement: All engineers who qualified in GATE 2026 are eligible to apply for PSU jobs.
  • Conclusion I: Some candidates eligible for PSU jobs qualified in GATE 2026.
  • Conclusion II: Engineers who did not qualify in GATE 2026 are not eligible for any government jobs.
  • Answer: I follows. II does NOT follow.
  • Why: If all GATE qualifiers are eligible for PSU jobs, then some PSU-eligible candidates are GATE qualifiers (I follows by logical conversion). The statement says nothing about other government job pathways — II adds a claim outside the statement’s scope.

• Example 6

  • Statement: Most students who score above 90% in aptitude tests get shortlisted in off-campus drives.
  • Conclusion I: All students who score above 90% in aptitude tests will be placed in a company.
  • Conclusion II: Some students shortlisted in off-campus drives scored above 90% in aptitude tests.
  • Answer: I does NOT follow. II follows.
  • Why: “Most” is not “all” (I overstates the quantity). “Shortlisted” is not “placed” (I changes the outcome entirely). II is safe: “most” implies at least some, so II follows.

• Example 7

  • Statement: No bank in India offers a fixed deposit rate above 9% per annum.
  • Conclusion I: Interest rates above 9% per annum are not available anywhere in the financial system.
  • Conclusion II: All bank FD rates in India are 9% per annum or below.
  • Answer: I does NOT follow. II follows.
  • Why: The statement covers only Indian banks. Other instruments or foreign institutions are outside its scope — I extends the claim impermissibly. II is a direct restatement and follows cleanly.

• Example 8

  • Statement: Students who attend soft-skills workshops consistently perform better in HR interview rounds.
  • Conclusion I: HR interview performance depends entirely on soft-skills training.
  • Conclusion II: Soft-skills workshops have a positive effect on HR interview performance.
  • Answer: I does NOT follow. II follows.
  • Why: “Consistently perform better” does not mean “depends entirely on” — I adds exclusivity that the statement does not assert. II is a direct extraction and follows.

Statements and Courses of Action

In this question type, a statement describes a problem. Two or more courses of action are proposed, and you decide which ones are valid practical responses.

The decision rule

A course of action is valid when it:

• Directly addresses the stated problem.
• Is feasible (not extreme, not operationally impossible).
• Is proportionate to the scale of the problem.
• Does not introduce new problems larger than the one being solved.

Worked examples

• Example 9

  • Statement: A large number of engineering graduates in India struggle to find employment in their core discipline.
  • Course of Action I: Engineering colleges should revamp their curricula to include industry-relevant skills alongside core subjects.
  • Course of Action II: All engineering colleges should be shut down immediately.
  • Answer: I follows. II does NOT follow.
  • Why: I is practical and directly addresses the curriculum-industry mismatch. II eliminates the system to solve a problem within the system — a disproportionate and impractical response.

• Example 10

  • Statement: Traffic congestion in Tier-2 city centres has increased during peak hours.
  • Course of Action I: Introduce staggered working hours for government offices to spread peak-hour load.
  • Course of Action II: Ban private vehicles from the city centre permanently.
  • Answer: I follows. II does NOT follow.
  • Why: I is a targeted, proportionate intervention that directly reduces peak congestion. II is extreme: a permanent ban is disproportionate to a congestion problem and operationally unfeasible.

• Example 11

  • Statement: A company found that fresher hires who had not practiced aptitude tests before joining required additional training time compared to those who had.
  • Course of Action I: The company should include a recommendation to practice aptitude tests in its offer letter.
  • Course of Action II: The company should stop hiring freshers who have not practiced aptitude tests.
  • Answer: I follows. II does NOT follow.
  • Why: I is a low-cost, practical intervention that directly reduces the training-time gap. II eliminates a category of candidates to avoid a training cost — disproportionate and impractical.

Common Traps in Critical Reasoning

The extension fallacy (assumptions)

The most common mistake in assumption questions: accepting an assumption that goes beyond what the statement strictly needs. If a statement says “take an umbrella because it might rain”, the required assumption is “umbrellas protect against rain”, not “it will definitely rain” and not “umbrellas are the best rain protection available”. Stay exactly as close to the statement as required, no further.

Strengthening versus assuming

An assumption is something that must be true for the argument to work. A fact that merely strengthens the argument is not an assumption. Test setters frequently offer a “strengthener” as one of the options, knowing it reads as implicitly necessary when it is not.

Over-strong conclusions

Conclusion questions almost always include one option that is nearly right but uses “all”, “always”, “never”, or “definitely” where the statement only supports “some”, “usually”, or “likely”. The stronger claim never follows from a weaker premise.

The feasibility filter for courses of action

Two proposed courses of action may both sound reasonable but differ on the feasibility dimension. An extreme response (shut down all schools, ban the product nationally, dismiss the entire team) is almost never a valid course of action regardless of how serious the problem is. The test rewards proportionate, implementable responses every time.

The same pattern-recognition skill that makes these questions tractable (identifying which conclusions follow from a statement, and which ones add new assumptions) applies when evaluating what an AI model actually says versus what you asked it. If checking whether a given assumption is strictly implicit is starting to feel systematic, TinkerLLM at ₹299 is a low-cost way to put that instinct to work with live language models.
