UGC NET Questions (Paper – 1)

The rule states that each letter is replaced by the next letter in the alphabet. For the word NET, N is followed by O, E is followed by F and T is followed by U. Replacing each letter accordingly, N becomes O, E becomes F and T becomes U, giving the code OFU. This maintains the same pattern that was used to convert WORD into XPSE.

Option A:
Option A correctly shifts every letter of NET forward by one position, providing O from N, F from E and U from T. It applies the coding rule consistently to all positions and thus matches the example given.

Option B:
Option B, OEU, shifts only some letters correctly and uses E instead of F for the second position. This breaks the uniform next-letter rule for the middle letter.

Option C:
Option C, MFS, shifts N backwards to M instead of forwards and only partially follows the pattern. It does not consistently apply the specified direction of shift.

Option D:
Option D, NEU, keeps N unchanged, which contradicts the rule that each letter must be replaced by its immediate successor in the alphabet.

Statement A describes a common pattern where letters are shifted forward or backward in the alphabet. Statement B acknowledges that rearranging letters, such as reversing or swapping positions, may be part of the code. Statement C is correct because within a single question, the same underlying rule is normally applied to all examples. Statement D is false; coding puzzles are designed to follow a discoverable rule, not random changes, and E is false because different words usually get different codes according to the rule. Hence A, B and C only are correct, which is option C.

Option A:
Option A is incomplete since it omits C, thereby failing to mention the crucial examination principle that a single consistent rule governs all codes in one question.

Option B:
Option B is incorrect as it adds E, which wrongly suggests that knowing one code fixes all others, ignoring the dependence on the specific letters of each word.

Option C:
Option C is correct because it brings together the main transformation techniques and the idea of rule consistency, while excluding D and E, which mischaracterise coding questions as random or uniform across all words.

Option D:
Option D is wrong since it includes D, which asserts randomness, contradicting the logic-based nature of such questions, and it omits A, thus losing a central pattern used in letter coding.

Statement C is wrong because coding–decoding questions are deliberately constructed so that the code is systematically related to the original word, often through shifts, reversals or other consistent transformations. Statements A, B, D and E are all correct: codes frequently use alphabet shifts, reversals or swaps, comparing several coded words is a key strategy and these questions clearly test pattern recognition and analysis. Since only C misrepresents the nature of coding–decoding, the set of wrong statements consists of C alone.

Option A:
Option A is incorrect because it labels both A and C as wrong, even though A correctly describes a very common rule where letters are replaced by those at fixed distances in the alphabet. Treating A as wrong would contradict standard practice in many aptitude questions.

Option B:
Option B is wrong because it includes E among the wrong statements, wrongly suggesting that coding–decoding questions do not assess pattern recognition. In reality, E is an accurate statement about the purpose of such questions.

Option C:
Option C is incorrect as it groups B, C and D together and thereby misclassifies B and D, which are true descriptions of common patterns and solution strategies. Including true statements in the “wrong” set shows that this option does not satisfy the requirement of the question.

Option D:
Option D is correct since it isolates C as the only statement that denies the logical structure underlying coding–decoding questions and leaves all accurate descriptions intact. It reinforces the idea that these items are structured and analysable, not random.

Statements A, B, D and E correctly describe typical features of coding–decoding items, while C and F are false. Letter and number coding often rely on systematic shifts or assignments, and reversing the order of letters is a common twist. These questions mainly test the ability to detect and apply patterns, not domain-specific facts. C is wrong because patterns must be applied consistently once discovered, and F is wrong because many items deliberately mix letter and number coding. Therefore A, B, D and E only is the correct combination.

Option A:
Option A is incomplete since it omits E, failing to highlight that the real goal is pattern recognition rather than subject knowledge. While A, B and D are true, they do not fully capture what the questions are measuring. Thus this option is not fully accurate.

Option B:
Option B is correct because it gathers all the true statements about how such questions are constructed and why they are used. It excludes C and F, both of which contradict the basic idea of a systematic pattern. This makes the option consistent with actual exam practice.

Option C:
Option C is wrong because it accepts F, claiming that mixed patterns are impossible, even though many test items use exactly that device. It also omits A, removing a straightforward description of letter coding. The combination therefore cannot be right.

Option D:
Option D is incorrect since it includes C, suggesting that patterns should be applied inconsistently, which would destroy the logic of coding questions. Although it mentions E, the presence of C makes the option invalid as a set of correct statements.

D is wrong because coding–decoding and analogy questions are an integral part of reasoning and are explicitly included under mathematical reasoning and aptitude in UGC NET Unit 5. These items require recognising and applying patterns, which is a key aspect of mathematical thinking. Statements A, B, C and E are all correct descriptions: coding relies on replacement by rules, solving requires discovering that rule, analogies use one pair to transfer a relationship to another, and letter codes often depend on alphabet positions or shifts. Hence, D alone is the incorrect statement.

Option A:
Option A is correct because it singles out D as the statement that misrepresents the syllabus and nature of reasoning questions, while leaving the accurate descriptions of coding and analogies untouched. It reflects the exam’s emphasis on pattern-based reasoning.

Option B:
Option B is incorrect because it treats C, which correctly explains the essence of analogy questions, as if it were also wrong. Analogies indeed work by mapping a known relationship onto a new pair.

Option C:
Option C is wrong since it marks B as incorrect along with D, even though B rightly points out that identifying the substitution pattern is crucial in coding–decoding. Ignoring this fact undermines the understanding of how such items are solved.

Option D:
Option D is also incorrect because it adds A to the set of wrong statements, even though A correctly states that coding–decoding involves replacing a word or number according to some rule. This option therefore misclassifies a core feature of coding questions.

The letters in LOGIC correspond to positions: L is 12, O is 15, G is 7, I is 9 and C is 3. Adding these positions gives 12 + 15 + 7 + 9 + 3 = 46. Therefore, the sum of the code numbers for LOGIC is 46.

Option A:
Option A exactly matches the sum of the letter positions and correctly applies the coding rule to every letter in the word.

Option B:
Option B, 49, is 3 more than the correct total and indicates an error in adding one or more of the letter values.

Option C:
Option C, 51, overshoots the correct sum by 5 and could result from misreading one of the letter positions.

Option D:
Option D, 52, is even farther from the true total and cannot be obtained by any correct application of the given mapping.

The rule states that each letter is replaced by its position in the alphabet and then all positions are summed. For NET, N is 14, E is 5 and T is 20. Adding these values gives 14 + 5 + 20 = 39. Since this computation matches the coding rule used in the example, 39 is the correct code for NET.

Option A:
Option A, 35, would require the sum of letter positions to be 35, but 14 + 5 + 20 clearly equals 39, not 35. This option therefore underestimates the actual total and ignores the correct arithmetic.

Option B:
Option B, 37, is also inconsistent with the required sum of positions, as there is no combination of N, E and T that would legitimately produce 37 under the stated rule. It likely arises from a miscalculation.

Option C:
Option C, 38, is again close to the correct answer but still incorrect because the precise sum 14 + 5 + 20 equals 39. In coding questions, even a small deviation from the rule’s outcome invalidates the option.

Option D:
Option D, 39, exactly matches the sum of the alphabetic positions of N, E and T. It faithfully applies the same coding procedure that produced 60 for WORD, making it the only option consistent with the defined rule.

Statements A, B and D accurately reflect common coding–decoding practices. A describes a typical letter-shift pattern used in many exam questions. B explains substitution coding where fixed word–symbol mappings are used. D is correct because analysing one clear example often reveals the pattern for others. C is false because the position of a letter in the word may affect its code, and E is false since different coding questions may use different patterns within the same paper. Therefore A, B and D only are correct.

Option A:
Option A is incomplete as it ignores D and so underplays the importance of pattern discovery from a given example, which is essential in solving such questions.

Option B:
Option B is correct because it includes all the standard features of these questions—letter shifting, substitution and pattern deduction—while excluding C and E, which express unsafe assumptions about position independence and uniform patterns.

Option C:
Option C is wrong since it accepts E (false) and omits A (true), so it cannot be correct.

Option D:
Option D is incorrect because it includes E (false) and omits B (true), so it cannot be correct.
