Learning Objective
Crack tougher analogies that combine letters with numbers or use two operations at once.
🎯 Learning Objective
Crack tougher analogies that combine letters with numbers or use two operations at once.
💡 Concept
- Mixed analogies pair a letter with a number, e.g. B2 : D4
- Solve the letter part and the number part separately, then combine
- Two-step letter patterns: first letter moves one way, second the other (A→forward, Z→backward)
- Two-step number patterns: n×(n+1), square-root links, or ×then±
- Never assume one rule — test the pair on BOTH its letter and number components
🧮 Key Formulas
Split mixed terms: solve letter and number separately
>
n × (n+1) product link
>
√ (square-root) link
>
Two-step: forward letter + backward letter
✏️ Easy Example
Q. B2 : D4 :: F6 : ?
- Letter: B→D is +2; Number: 2→4 is +2
- Apply to F6: F→H (+2), 6→8 (+2)
Answer: H8
🇮🇳 Real-Life Example
Seat labels like B2, D4, F6 on a train coach follow a two-part pattern — a letter series and a number series running together, just like a mixed analogy.
📝 Exam-Level Example
Q. AZ : BY :: CX : ?
- First letters A, B, C move forward → next is D
- Second letters Z, Y, X move backward → next is W
Answer: DW
📝 Exam-Level Example
Q. 7 : 56 :: 9 : ?
- 7 → 56 because 7 × 8 = 56, i.e. n × (n+1)
- So 9 → 9 × 10 = 90
Answer: 90
📝 Exam-Level Example
Q. 16 : 4 :: 64 : ?
- 16 → 4 because √16 = 4 (square-root link)
- So 64 → √64 = 8
Answer: 8
🪄 Memory Trick
Break every mixed term into its pieces and pattern each piece on its own — two easy one-step patterns beat one confusing 'combined' rule every time.
⚠️ Common Mistakes
- ❌ Forcing a single rule on both the letter and number parts
- ❌ Missing the product link n×(n+1) and trying only addition
- ❌ Moving both letters the same way when one goes forward and the other backward
🏆 Exam Tips
- ✅ Handle the letter component and number component in separate lines
- ✅ When a number shrinks a lot, test square roots and division, not just subtraction
📌 Summary
- Split mixed terms; pattern letters and numbers separately
- Watch for forward+backward letter pairs
- Test n×(n+1), squares and square-roots for number links
- Two simple one-step patterns beat one 'combined' guess
