Reasoning Analogy Types

Analogy Types – Quick Revision Sheet for RRB

1. Key Concepts – Must Know

  • Analogy = Relationship between two pairs; find the missing pair that keeps the same relation
  • Always spot the PRIMARY relation first; secondary checks come later
  • Direction of relation matters: A → B is not always same as B → A
  • Five super-frequent relations:
    1. Synonym/Antonym
    2. Worker–Tool–Work
    3. Whole–Part / Part–Whole
    4. Class–Member / Member–Class
    5. Cause–Effect / Raw–Product

2. Golden Rules / Formulas

Rule # Formula (in words) Example
1 First → Second = Third → ? Water : Dam :: Traffic : ? → Flyover
2 Keep same “unit/grammar” Noun → Noun, Verb → Verb, Singular → Singular
3 Degree check Hot → hottest, Big → biggest
4 Reverse order check If first pair is Part → Whole, second pair must be Part → Whole
5 Eliminate odd one in options → 3 will break the exact relation

3. Speed Tricks & Shortcuts

  • “Bridge sentence” trick: make a tiny sentence with first pair, force it on third word → missing word pops out
    “Pen is used to write; Axe is used to cut.”
  • Word-stem check: remove prefix/suffix; root must match
    Happy : Unhappy :: Able : Unable
  • GK blast: Indian capital, rivers, dams, sports trophies, computer terms appear every 3rd question
  • Number analogy: look for square, cube, ×2+1, ×3−1 pattern first
  • Alphabet analogy: write A-1 to Z-26 above question; difference or reverse-difference gives answer in 5 s

4. Mnemonics – 60-Second Memory

  • “SWEAR” – five killer relations:
    Synonym, Worker-Tool, Effect-Cause, Animal-Young-one, Raw-Product
  • “NOUN-CHECK” – Never forget grammar match:
    Number, Order, Unit, Nature (Noun/Verb/Adj)
