Infosys Logical Reasoning Questions 2026

20 September 2026 · Pocket Aptitude Team

Infosys tests Logical Reasoning as one of three sections in its placement exam, alongside Quantitative Aptitude and Verbal Ability. Based on current prep-site reporting, it’s commonly described as the toughest of the three. Expect syllogisms, blood relations, coding-decoding, statement-conclusion, data sufficiency, and arrangement/puzzle questions, under a strict per-section time limit with a sectional cutoff.

A note on sourcing before we go further: there’s no official, published Infosys question bank, and no verified candidate-reported “these exact questions were asked” available anywhere online right now — what exists is topic-pattern reporting compiled by prep sites, some of which repeat the same claims. This guide is built from that pattern reporting, clearly framed as commonly reported patterns rather than confirmed leaked questions. If you’re preparing for a specific Infosys drive, always cross-check the current format against your actual test invite, since patterns do change between hiring cycles.

If coding-decoding specifically comes up in your practice, see our full Coding and Decoding Aptitude Questions guide for concepts, types, and solved examples.

What Type of Logical Reasoning Questions Does Infosys Ask?

Across current prep-site pattern reporting, the topics named most consistently for Infosys’s logical reasoning section are:

  • Syllogisms — drawing valid conclusions from given statements
  • Blood relations — family-relationship puzzles
  • Coding-decoding — letter/number/symbol transformation rules
  • Statement and conclusion / statement and assumption — judging whether a conclusion logically follows
  • Data sufficiency — deciding whether given data is enough to answer a question, without solving it fully
  • Seating arrangement and puzzles — linear, circular, or grid-based arrangement logic
  • Cryptarithmetic — letter-for-digit substitution problems

These are reported as a mix within the section rather than one topic dominating — expect a spread across several of the above rather than repeated questions on just one or two.

Infosys Logical Reasoning Section at a Glance

Figures below are commonly reported ranges compiled from current prep-site pattern data, not an official Infosys specification — treat them as a planning guide, and confirm against your own test invite where possible.

DetailCommonly reported figure
Number of questionsAround 15
Time allottedRoughly 25–35 minutes (sources vary)
Negative markingNot typically reported
CutoffSectional cutoff applies — a weak score here isn’t offset by strong quant/verbal scores

Solved Example in the Infosys Pattern

This is a practice example written in the reported Infosys style — not a claim that this specific question has appeared on a real Infosys test.

Question (Blood Relations): Pointing to a photograph, Rahul said, “She is the daughter of my grandfather’s only son.” How is the girl in the photograph related to Rahul?

Solution: Rahul’s grandfather’s only son is Rahul’s father (since it’s the only son). The girl is the daughter of Rahul’s father — so she is Rahul’s sister.

Question (Coding-Decoding): If TABLE is coded as UBCMF, how is CHAIR coded using the same rule?

Solution: Each letter moves one position forward in the alphabet (T→U, A→B, B→C, L→M, E→F). Applying the same rule to CHAIR: C→D, H→I, A→B, I→J, R→S, giving DIBJS.

How to Prepare for Infosys Logical Reasoning in a Short Time

Start with the topics reported most frequently — syllogisms, blood relations, and coding-decoding — since they’re the ones current prep-site pattern data names most consistently. Practice under the reported time pressure (roughly 1.5–2 minutes per question) rather than untimed, since the sectional cutoff means both accuracy and speed matter. Puzzles and arrangements typically take longer per question, so it’s worth deciding in advance how much time you’ll allow before moving on, rather than getting stuck on one.

Frequently Asked Questions

How many logical reasoning questions does Infosys ask, and how much time do you get?

Commonly reported figures suggest around 15 questions in roughly 25–35 minutes, though exact numbers vary by source and hiring cycle — confirm against your own test invite.

What are the most common logical reasoning topics in the Infosys exam?

Syllogisms, blood relations, coding-decoding, statement-conclusion, data sufficiency, and seating arrangement/puzzles are the topics named most consistently across current prep-site reporting.

Is there negative marking in the Infosys logical reasoning section?

Negative marking isn’t typically reported for this section, but always verify against your specific test instructions, since this can change between hiring cycles.

Is logical reasoning really the toughest section in the Infosys exam?

It’s commonly described that way across prep sites, though this claim appears to be repeated across sources rather than independently measured each time — treat it as a general signal that it deserves focused practice, not a guarantee.

Are the same questions asked every year?

No. There’s no evidence of a fixed, recurring question bank — prep sites report topic patterns and practice questions in the Infosys style, not confirmed past exam questions. Preparation should focus on mastering the topic types, not memorizing specific questions.

How should I prepare for Infosys logical reasoning in a short time?

Focus first on the most frequently reported topics (syllogisms, blood relations, coding-decoding), practice under a strict time limit, and decide in advance how long you’ll spend on a puzzle question before moving on.
