CoCubes Logical Reasoning Questions 2026: Practice Set with Answers

CoCubes logical reasoning tests three distinct skills in a single section: inductive reasoning (patterns and rules), deductive reasoning (cause-and-effect and statement analysis), and visual or spatial reasoning (figure rotation and pattern completion).

The three sub-areas are weighted differently across drives. CoCubes’ full test structure (section timing and score thresholds) is managed by HirePro, which now runs the CoCubes platform. For the quantitative side of the test, the CoCubes aptitude practice set covers numerical reasoning in the same format. If your drive includes a coding component, CoCubes coding questions covers that section.

This article works through 15 questions drawn from all three sub-areas with full explanations. Visual questions from legacy sources are image-dependent and can’t be reproduced in text; the visual section below explains the format and preparation approach instead.

What the CoCubes Logical Reasoning Section Covers

CoCubes, administered through the HirePro campus hiring platform, allows companies to configure which reasoning sub-areas appear and how many questions each carries. The three standard sub-areas are:

Sub-area	What it tests	Common question types
Deductive Reasoning	Rule application, logical consequence	Cause and effect, statement-assumption, syllogisms
Inductive Reasoning	Pattern and rule extraction	Coding-decoding, blood relations, number series, odd one out
Visual and Spatial Reasoning	Figure recognition and transformation	Pattern completion, figure rotation, embedded figures

Most standard CoCubes drives allocate the largest share of logical reasoning marks to deductive questions, with cause-and-effect being the single most repeated template. Visual reasoning questions appear in most drives but typically carry fewer questions than the other two sub-areas.

No negative marking applies in standard configurations. Attempt every question.

Deductive Reasoning: Cause and Effect Questions

Cause-and-effect questions give you two statements and ask you to determine whether one caused the other, both are effects of a common cause, or they are independent. Read both statements before selecting an option. The most common error is locking in the direction of causation on the first statement alone.

The five answer options in CoCubes format are:

• (a) Statement I is the cause and Statement II is the effect
• (b) Statement II is the cause and Statement I is the effect
• (c) Both are independent causes
• (d) Both are effects of independent causes
• (e) Both are effects of a common cause

Practice Questions

• Q1: Statement I: Most students in this college opposed the administration’s plan to leave the university and become autonomous. Statement II: The university said it cannot provide further grants to its affiliated colleges.

• Answer: (b) Statement II is the cause and Statement I is the effect.

• Explanation: The university withdrawing grants is the trigger. The college administration responds by seeking autonomy; students then react to that decision. The financial withdrawal drives the chain.

• Q2: Statement I: Police used force to break up an unlawful gathering. Statement II: A citizens’ forum called a strike to protest police conduct.

• Answer: (a) Statement I is the cause and Statement II is the effect.

• Explanation: A mass public gathering prompts the police action; the forceful dispersal then prompts a protest strike. The sequence runs I → II.

• Q3: Statement I: Most students in government school final exams performed well. Statement II: Several teachers left government schools to join private schools.

• Answer: (d) Both are effects of independent causes.

• Explanation: Strong student results and teacher attrition both happen in government schools, but they have separate drivers — exam preparation on one side, salary differentials on the other. Neither event caused the other.

• Q4: Statement I: National highways are in poor condition. Statement II: The government has approved a large fund to maintain national highways.

• Answer: (a) Statement I is the cause and Statement II is the effect.

• Explanation: The poor condition is the documented problem. The budget approval is the administrative response. Direct cause-and-effect, I → II.

• Q5: Statement I: Modern life is fast-paced, demanding, and stressful. Statement II: The number of teenage suicide cases has risen.

• Answer: (a) Statement I is the cause and Statement II is the effect.

• Explanation: Chronic stress from high-pressure environments is a documented risk factor for extreme outcomes in vulnerable populations. The first statement describes the condition; the second describes one consequence.

Inductive Reasoning: Coding-Decoding and Blood Relations

Coding-decoding questions test whether you can identify the transformation rule applied to a word or letter sequence and apply it to a new word. Blood-relation questions test whether you can track family connections through a chain of statements.

Coding-Decoding Questions

• Q6: If FASHION is coded as FOIHSAN, what is the code for PROBLEM?

• Options: A) ROBLEMP B) PRBOELM C) PELBORM D) PRBOELM

• Answer: C) PELBORM

• How to solve: Compare FASHION → FOIHSAN letter by letter: F-A-S-H-I-O-N becomes F-O-I-H-S-A-N. The first letter stays (F→F). The remaining six letters (A-S-H-I-O-N) are reversed (N-O-I-H-S-A) but then the first of those six is swapped to position 2 and the second to position 3… Let me re-examine: FASHION = F,A,S,H,I,O,N and FOIHSAN = F,O,I,H,S,A,N. Mapping: position 1(F)→F, 2(A)→O, 3(S)→I, 4(H)→H, 5(I)→S, 6(O)→A, 7(N)→N. So positions 2 and 6 are swapped, positions 3 and 5 are swapped, positions 1, 4, 7 stay. Apply to PROBLEM (P,R,O,B,L,E,M): swap positions 2 and 6 (R↔E), swap positions 3 and 5 (O↔L): P,E,L,B,O,R,M = PELBORM. Answer: C.

• Q7: In a certain code, BODE is written as @$*? and EAT is written as ?. If DEBATE has to be coded, what is the result?

• Answer: Cannot be determined from the information given without the complete EAT code mapping. The WP original provides incomplete cipher data for this question; treat it as a “decode the rule” exercise to recognise incomplete information.

Blood Relations Questions

• Q8: Raju says about Manju: “The son of her only brother is the brother of my wife.” How is Manju related to Raju?

• Options: A) Mother’s sister B) Grandmother C) Mother-in-law D) Sister of father-in-law E) Maternal aunt

• Answer: D) Sister of father-in-law

• Explanation:

  • Step 1: “The brother of my wife” = Raju’s brother-in-law.
  • Step 2: “Son of Manju’s only brother” = that same person.
  • Step 3: So Manju’s brother’s son = Raju’s brother-in-law. This means Manju’s brother = Raju’s father-in-law.
  • Step 4: Manju is the sister of Raju’s father-in-law.

• Q9: A is the husband of B. E is the daughter of C. A is the father of C. How is B related to E?

• Options: A) Mother B) Grandmother C) Aunt D) Cousin

• Answer: B) Grandmother

• Explanation:

  • Step 1: A and B are spouses.
  • Step 2: A is father of C; so C is the child of A and B.
  • Step 3: E is daughter of C; so E is A’s grandchild.
  • Step 4: B is A’s spouse and C’s mother, so B is grandmother to E.

Inductive Reasoning: Number Series and Odd One Out

Number series questions ask you to identify the pattern connecting consecutive terms and find a missing number or the one that breaks the pattern. Derive the rule from the differences between consecutive terms before looking at the answer choices.

Number Series and Odd One Out Questions

• Q10: Find the missing number: 2, 6, 12, 20, ?, 42

• Options: A) 28 B) 30 C) 32 D) 34

• Answer: B) 30

• How to solve:

  • Differences between consecutive terms: 6-2=4, 12-6=6, 20-12=8, ?-20=?, 42-?=?
  • The differences form the sequence 4, 6, 8, 10, 12 (increasing by 2 each time).
  • Missing term = 20 + 10 = 30. The next difference would be 12, giving 30 + 12 = 42 ✓.

• Q11: Find the odd one out: 7, 8, 12, 20, 37, 62

• Options: A) 37 B) 62 C) 12 D) 20

• Answer: D) 20

• How to solve:

  • Test the pattern: add successive perfect squares — 1, 4, 9, 16, 25.
  • 7 + 1² = 7 + 1 = 8 ✓
  • 8 + 2² = 8 + 4 = 12 ✓
  • 12 + 3² = 12 + 9 = 21 (but the sequence shows 20 — this is the break)
  • If the sequence were correct: 21 + 4² = 21 + 16 = 37 ✓ and 37 + 5² = 37 + 25 = 62 ✓.
  • Conclusion: 20 should be 21. The odd one out is 20.

• Q12: A tiebreaker is an additional contest designed to establish a winner among tied contestants. Which situation best describes a tiebreaker?

• Options: A) At halftime the score is 28-28. B) Mary and Megan have each scored three goals. C) The referee tosses a coin to decide kick-off. D) The Sharks and the Bears finished level on 14 points and are now in a five-minute overtime period.

• Answer: D

• Explanation: Options A and B describe a tie — not a tiebreaker. Option C is a procedural coin toss, not a contest to break a tie. Option D matches the definition exactly: additional play designed to establish a winner among teams that finished level.

Visual and Spatial Reasoning: What to Expect

Visual reasoning questions in CoCubes use images: figure rotation, pattern completion, and embedded figures. These questions cannot be reproduced in text format because the answer choices are figures, not words or numbers.

What the questions test:

• Figure rotation: A shape is shown; you select which answer choice shows it after a 90-degree or 180-degree rotation.
• Pattern completion: A matrix of figures follows a row-and-column rule; you identify which figure completes the missing cell.
• Embedded figures: A complex figure contains a simpler shape hidden inside it; you identify which simpler shape is embedded.

Preparation approach: Practise with image-based reasoning question banks from the HirePro sample test portal or preparation platforms that include visual reasoning sets. The cognitive skill is recognising spatial transformations quickly rather than calculating them. Speed comes from repeated exposure to rotation and reflection patterns, not from memorising specific figures.

CoCubes Logical Reasoning and Analytical Thinking for Placements

The cause-and-effect questions in this article demand one specific skill: identifying which event precedes and produces another, as opposed to two events that happen simultaneously for unrelated reasons. That same skill (tracing consequence chains, distinguishing causation from correlation) is increasingly relevant in technical roles that involve AI tools.

Engineers working with LLM outputs need to ask “does the model’s conclusion follow from the prompt, or did something else in the context drive it?” That’s the same question structure as CoCubes Q1 through Q5.

If you want to practise that kind of reasoning in a live environment, TinkerLLM is an AI playground where you can run experiments on reasoning chains for ₹299. The logical analysis patterns this article drills have a direct application there.
