Why this chapter matters in CUET UG
General Mental Ability tests the same pattern-recognition instinct as Logical & Analytical Reasoning, but every question resolves in a single step once its type is correctly identified — there is no multi-clue chain to track, which makes speed of TYPE recognition, not calculation, the decisive factor.

General Mental Ability — CUET UG General Test

General Mental Ability sits alongside Logical & Analytical Reasoning at a distinctly simpler level: every question here resolves in a single step once the underlying pattern or relationship is spotted, with no multi-clue chain to track. The entire skill is recognising WHICH kind of pattern is in front of you — an analogy, a classification, a series — since each type has its own short, fixed method once identified.

1. Analogies

An analogy question states a relationship between a first pair of words or numbers, and asks for a second pair that shares the EXACT SAME relationship — identifying the relationship's type precisely, not just noting that the two pairs are "related" in some vague sense, is the whole skill. Common relationship types include part-to-whole, cause-to-effect, item-to-purpose (action), item-to-typical-location (place), and opposites.

Fish is to Water as Bird is to Sky (a place/habitat relationship). Knife is to Cut as Pen is to Write (a tool-to-its-action relationship). Hot is to Cold as Day is to Night (an opposites relationship).

2. Number analogies

Number analogies apply the identical logic to numbers instead of words — the relationship is usually a fixed arithmetic operation, most often squaring, doubling, or a fixed addition/subtraction, applied consistently to both given pairs. pairs with (both follow "square the first number"), since and .

3. Classification (odd one out)

A classification question gives several items and asks which one does NOT share the property common to all the others — the method is identifying what property connects the majority first, then checking each item against that specific property, rather than guessing based on a vague sense of similarity. Given , the first four are all perfect squares () while 30 is not — making 30 the odd one out.

The same method applies to shapes and words: find the property shared by most of the items (number of sides, a grammatical category, a specific attribute) before deciding which single item breaks that pattern.

4. Number series

A number series gives several terms and asks for the next one, and identifying the series' TYPE is the entire task — the calculation afterward is always a single, direct step. The main types worth recognising on sight are:

Series typeExampleRule
Arithmetic5, 9, 13, 17, ?Constant difference (+4 each time)
Geometric2, 6, 18, 54, ?Constant ratio (×3 each time)
Squares1, 4, 9, 16, 25, ? for
Primes2, 3, 5, 7, 11, ?Each term is the next prime number
Fibonacci1, 1, 2, 3, 5, 8, ?Each term is the sum of the two before it
2, 6, 12, 20, 30, ? for

5. Letter series

Letter series apply the identical logic to letters, using their position in the alphabet (A=1 through Z=26) as the underlying number — a series can move forward or backward through the alphabet, with a constant or changing step size, exactly like a number series. The series Z, X, V, T, ? steps backward by 2 letters each time, so the next letter is R.

6. Coding-decoding

At this level, coding-decoding is almost always a fixed, constant letter shift applied to every letter of a word — identify the shift from the one worked example given, then apply that exact same shift to every letter of the new word. This is the same method used in Logical & Analytical Reasoning's coding questions, just tested here in isolation rather than alongside other reasoning clues.

7. Direction sense (basic)

At the General Mental Ability level, direction-sense questions typically involve just one or two turns rather than the longer multi-leg journeys seen in Logical & Analytical Reasoning — track the final facing direction and net position using the same independent-axis method, just with fewer steps to combine.

Worked Examples

Example 1. Complete the analogy: Wheel is to Car as Wing is to ?

A wheel is a part enabling a car's motion; a wing is the corresponding part enabling flight.

Answer: Aeroplane / Bird.

Example 2. Complete the analogy: Doctor is to Hospital as Teacher is to ?

A doctor's typical place of work is a hospital; a teacher's typical place of work is a school.

Answer: School.

Example 3. Complete the number analogy:

The relationship is "square the first number": , so .

Answer: 49.

Example 4. Find the odd one out: 121, 144, 169, 200, 225.

, , , are all perfect squares; 200 is not.

Answer: 200.

Example 5. Find the odd one out: Triangle, Square, Pentagon, Circle, Hexagon.

Triangle, Square, Pentagon and Hexagon are all polygons with a fixed number of straight sides (3, 4, 5, 6); a circle has no straight sides at all.

Answer: Circle.

Example 6. Find the next term: 5, 9, 13, 17, ?

Each term increases by a constant 4 (arithmetic series): .

Answer: 21.

Example 7. Find the next term: 2, 6, 18, 54, ?

Each term is 3 times the previous one (geometric series): .

Answer: 162.

Example 8. Find the next term: 2, 6, 12, 20, 30, ?

Each term follows : for to the terms are ; for : .

Answer: 42.

Example 9. Find the next letter: B, E, H, K, ?

Each letter moves forward by 3 positions in the alphabet (B=2, E=5, H=8, K=11): the next is position 14, which is N.

Answer: N.

Example 10. If FLOWER is coded as GMPXFS (each letter shifted forward by 1), how is GARDEN coded in the same rule?

Applying the +1 shift to each letter: G→H, A→B, R→S, D→E, E→F, N→O.

Answer: HBSEFO.

Example 11. A man faces north, turns 90° clockwise, walks 5 km, then turns 90° clockwise again and walks 5 km. In which direction is he now facing, and how far is he from the start?

Facing north, a 90° clockwise turn faces him east; walking 5 km east. A second 90° clockwise turn faces him south; walking 5 km south. He now faces south. His net position: 5 km east and 5 km south of the start, a straight-line distance of km.

Answer: Facing south, approximately 7.07 km from the start.

Summary

Every General Mental Ability question resolves in one step once its pattern TYPE is correctly identified — analogy, classification, number/letter series, coding, or basic direction.

Analogies require matching the exact same relationship type (part-whole, action, place, opposites) in a second pair, not merely a vague sense of relatedness. Classification finds the property shared by the majority first, then checks which single item breaks it.

Number and letter series come in a small fixed set of recognisable types — arithmetic, geometric, squares, primes, Fibonacci, and formula-based patterns like — and identifying the type is the entire task, since extending it afterward is a single direct calculation. Coding-decoding and basic direction-sense questions apply the same fixed-rule and independent-axis methods taught more extensively in Logical & Analytical Reasoning, just in shorter, single-step form here.

Traps CUET UG sets — and how to dodge them

These are the exact option-traps and misreads that cost marks under negative marking.

WATCH OUT
Matching an analogy pair based on a vague sense of relatedness rather than the exact same relationship type
State the first pair's relationship precisely in words (e.g. 'typical location,' 'tool used for,' 'opposite of') before checking which answer option shares that exact relationship.
Why it happens: Several answer options are usually loosely related to the given word; only one shares the SAME specific relationship as the original pair.
WATCH OUT
Identifying a classification group's property incorrectly, based on only 2-3 of the items instead of all but one
Check the candidate property against every item except the suspected odd one out, confirming it holds for the full majority before finalising an answer.
Why it happens: A property that fits only some of the 'majority' items is not actually the shared property connecting them, and leads to picking the wrong odd one out.
WATCH OUT
Assuming every number series is arithmetic (constant difference) without checking other series types
If the difference between consecutive terms is not constant, check whether the RATIO is constant (geometric), or whether the terms match squares, primes, Fibonacci, or a formula like n^2+n.
Why it happens: Non-arithmetic series are common at this level, and applying an arithmetic rule to them produces a confidently wrong next term.
WATCH OUT
Losing track of which direction is 'clockwise' relative to the current facing direction after a turn
Explicitly state the new facing direction after each turn (e.g. 'facing north, turn clockwise, now facing east') before taking the next step.
Why it happens: A clockwise or anticlockwise turn's actual resulting direction depends on which way the person is currently facing, not a fixed compass rule.

5-minute revision

The whole chapter, distilled. Read this the night before the exam.

  • Analogies require matching the EXACT relationship type of the first pair — state it precisely in words before checking the options.
  • Classification finds the property shared by the majority (checked against every item except the suspected odd one), then identifies which single item breaks it.
  • Recognise number series types on sight: arithmetic (constant difference), geometric (constant ratio), squares, primes, Fibonacci, and formula-based series like n^2+n.
  • Letter series convert to number series using alphabet position (A=1 to Z=26).
  • Coding-decoding at this level is a fixed, constant letter shift — identify it from the sample word before reapplying it.
  • Direction-sense questions use independent north-south and east-west tracking, combined via the Pythagorean relationship only when a straight-line distance is asked for.

Exam-hall strategy

Battle-tested tips from mentors and toppers for this topic under the sectional clock.

  1. For analogies, state the first pair's relationship in a short, precise phrase before scanning the options.
  2. For classification, test the suspected shared property against every 'majority' item, not just a couple of them.
  3. For number and letter series, check difference first, then ratio, then squares/primes/Fibonacci/formula patterns, in that order, until one fits.
  4. For coding-decoding, verify the identified shift against every single letter of the sample word before reapplying it.
  5. For direction-sense questions, explicitly restate the current facing direction after every turn before taking the next step.

Beyond the exam

Where this skill shows up in the job you're competing for — and in life.

Quick pattern spotting

Recognising which type of pattern (additive, multiplicative, formula-based) underlies a sequence of numbers is a transferable skill for reading trends in any numeric data.

Precise categorisation

Classification's discipline of stating a shared property precisely before excluding an item is directly useful in sorting, tagging, or auditing any dataset for outliers.

Questions aspirants ask

Pulled from the Q&A community and mentor sessions.

Roughly 6-8 of the General Test's 50 questions, based on pattern analysis of released sample papers.

General Mental Ability tests single-step pattern recognition (analogies, classification, series, basic coding) with no multi-clue chain, while Logical & Analytical Reasoning tests multi-fact puzzles (blood relations, seating, syllogisms) that need a drawn diagram to track several clues at once.

Arithmetic (constant difference), geometric (constant ratio), perfect squares, primes, Fibonacci-type (sum of the previous two terms), and formula-based series such as n^2+n. Recognising the type is the entire task.

The method is identical — identify a fixed letter shift from a sample word and reapply it — but General Mental Ability tests it as a standalone, single-step question rather than combined with other reasoning clues.

No — at this level they typically involve just 1-2 turns, unlike the longer journeys sometimes seen in Logical & Analytical Reasoning. The same independent-axis tracking method applies either way.
