Why this topic matters · 7 min read
Analogies are a core Reasoning topic in Bihar Police Constable exams, typically appearing in 3-5 questions per paper. You are given a pair (A:B) and must find the relationship, then apply it to find C:D. Questions mix word analogies (semantic), letter analogies (position/pattern), and number analogies (arithmetic/sequence). Speed and pattern recognition are critical—most aspirants lose marks by overthinking or missing the simplest relationship.
What is an Analogy and Why It Matters
An analogy tests your ability to recognize relationships between pairs of items. The format is always A:B::C:? or A:B::C:D (where you pick D from options). In Bihar Police exams, analogies appear in both verbal (word-based) and non-verbal (letter/number-based) forms. The relationship can be semantic (meaning-based), positional (alphabet order), mathematical (arithmetic), or categorical (classification). The key skill is to identify the EXACT relationship in A:B, then replicate it for C:?.
- Analogies test logical reasoning and pattern recognition, not memorization
- Three main types: Word analogies (Lion:Animal), Letter analogies (A:B::C:D in alphabet), Number analogies (2:4::3:?)
- Always identify the relationship in the first pair BEFORE looking at options
- The relationship must be reversible or consistent—if A→B, then C→D must follow the same rule
- Bihar Police papers often mix all three types in a single section to test adaptability
Word Analogies: Semantic Relationships
Word analogies rely on meaning and category relationships. Common patterns include: Part-to-Whole (Wheel:Car), Cause-and-Effect (Rain:Flood), Synonym (Happy:Joyful), Antonym (Hot:Cold), Function (Knife:Cut), Classification (Rose:Flower), and Association (Doctor:Hospital). The trick is to state the relationship as a sentence: 'A is to B as C is to D.' For example, 'Lion is to Animal as Rose is to Flower' works because both are part-to-whole relationships. If you can't complete the sentence naturally, the relationship is wrong.
- Part-to-Whole: Finger:Hand, Petal:Flower, Brick:Wall
- Cause-Effect: Study:Success, Carelessness:Accident, Heat:Evaporation
- Synonym/Similar: Brave:Courageous, Tiny:Small, Intelligent:Smart
- Antonym/Opposite: Day:Night, Rich:Poor, Bitter:Sweet
- Function/Purpose: Pen:Write, Hammer:Nail, Thermometer:Temperature
- Association/Location: Teacher:School, Fish:Water, Pilot:Cockpit
Letter Analogies: Alphabet Position and Pattern
Letter analogies work with the position of letters in the alphabet or patterns formed by letters. A=1, B=2, ..., Z=26. Common patterns include: position jumps (A:C means +2 positions), reverse alphabets (A:Z means opposite ends), and letter sequence patterns. For example, B:D::F:H means each letter is 2 positions ahead in the alphabet. Another type is letter reversal: ABC:CBA. The key is to convert letters to numbers, find the mathematical relationship, then apply it to the second pair.
- Position-based: A:C (skip 1), B:E (skip 2), Z:X (go back 2)
- Reverse/Opposite: A:Z, B:Y, M:N (middle letters)
- Sequence: ABC:DEF (shift all by 3), BCD:EFG (shift by 3)
- Alternating: ACE:BDF (odd vs even positions in alphabet)
- Always convert to numbers first: A=1, B=2, etc., then find the rule
- Watch for bidirectional patterns—sometimes the relationship works both ways
Number Analogies: Arithmetic and Sequence Patterns
Number analogies involve arithmetic operations, sequences, or mathematical properties. Common patterns include: addition/subtraction (2:5 means +3), multiplication/division (2:8 means ×4), squares/cubes (2:4 means square), and composite patterns (2:6 means ×3, then +1). The process is: identify the operation linking A to B, then apply the same operation to C to find D. For example, if 3:9 (multiply by 3), then 5:? should be 15. Some questions use digit sums or prime numbers—stay alert to the context.
- Addition: 5:8 means +3, so 10:? is 13
- Multiplication: 3:12 means ×4, so 5:? is 20
- Squares: 3:9 (3²), 4:16 (4²), so 5:? is 25
- Composite: 2:5 (×2+1), 3:7 (×2+1), so 4:? is 9
- Digit sum: 23:5 (2+3=5), 34:7 (3+4=7), so 45:? is 9
- Prime/Special: Identify if numbers are prime, perfect, or follow a sequence
Mixed and Complex Analogies
Bihar Police papers sometimes combine word, letter, and number analogies in tricky ways. For instance, a question might ask: 'APPLE:5::MANGO:?' where you count letters. Or 'CAT:3::DOG:?' where you use alphabet positions (C=3, A=1, T=20 sum to 24; D=4, O=15, G=7 sum to 26). The strategy is to identify which type of analogy you're dealing with, then apply the appropriate rule. Read the question carefully—sometimes the relationship is hidden in the structure of the words themselves, not just their meaning.
- Letter-count analogies: APPLE:5 (5 letters), MANGO:5 (5 letters)
- Alphabet-sum analogies: CAT (3+1+20=24), DOG (4+15+7=26)
- Hybrid analogies: Mix word meaning with letter/number properties
- Position-based word analogies: First letter, last letter, or middle letter patterns
- Always check if the question is asking for a word, letter, or number as the answer
⚠ Common mistakes to avoid
- Identifying the wrong relationship: Aspirants pick the first relationship that seems to fit, without checking if it works for the second pair. Always verify: if A→B by rule R, does C→D also follow rule R?
- Overthinking simple relationships: A question might be as simple as 'opposite' or 'part-to-whole,' but aspirants hunt for complex patterns. Start with the simplest relationship first.
- Confusing letter position with letter value: A=1 in alphabet position, but in some questions, A might represent a different value. Read the question setup carefully.
- Ignoring the direction of the relationship: Some relationships are one-way (Cause→Effect) while others are bidirectional (Synonym). Misidentifying direction leads to wrong answers.
- Rushing through options without re-checking: Bihar Police papers have tricky distractors. Always substitute your answer back into the original analogy to confirm it works.
🧠 Memory aids
- SCFAP: Semantic, Cause-Effect, Function, Association, Part-to-whole—the five main word analogy types. Remember them in order.
- ABC Rule: Always identify the relationship in A:B first, then apply it to C:? to find D. Don't jump to options.
- Letter=Number: Convert letters to numbers (A=1, Z=26) for letter analogies. Makes patterns visible.
- Verify Both Pairs: If A:B works by rule R, confirm C:D also works by rule R. One pair matching is not enough.
🎯 BIHAR POLICE CONSTABLE exam tips
- Bihar Police Constable papers typically include 3-5 analogy questions in the Reasoning section. They appear in both verbal and non-verbal formats within the same test.
- Time management: Spend 45-60 seconds per analogy question. If you can't identify the relationship in 30 seconds, skip and return. Analogies reward pattern recognition, not calculation.
- Word analogies are more common (60%) than letter or number analogies (40%). Strengthen your semantic relationship vocabulary—study part-to-whole, cause-effect, and function pairs.
- Recent Bihar Police papers show a trend toward mixed-type analogies (e.g., word + letter count). Practice hybrid questions to stay ahead.
- Options often include plausible-sounding but incorrect answers. Always re-verify your chosen answer by substituting it back into the analogy format before finalizing.
