🔍 Odd Man Out
Ek group mein se wo item dhundho jo baaki sabse alag hai — common pattern dekho!
Step 1: Pehle dekho kya common hai — category, shape, number pattern, alphabets
Step 2: Jo element match na kare woh odd one out hai
Example 1: 2, 4, 6, 9, 10, 12
Sab even hain except
9 (odd number) → Odd one out =
9
Example 2: Dog, Cat, Cow, Eagle, Horse
Sab domestic animals hain except
Eagle (bird) → Odd one out =
Eagle
Example 3: 17, 23, 37, 43, 49, 53
Sab prime numbers hain except
49 (= 7²) → Odd one out =
49
💬 Syllogism
Do ya zyada statements se logical conclusion nikalna. Venn diagrams se solve karo!
Types of statements:
All A are B → A ⊂ B (circle A fully inside B)
Some A are B → A ∩ B ≠ ∅ (partial overlap)
No A is B → A ∩ B = ∅ (no overlap)
Some A are not B → part of A is outside B
Example: All cats are animals. All animals are living things. Conclusion?
All cats are animals → Cats ⊂ Animals
All animals are living → Animals ⊂ Living
∴ Cats ⊂ Living →
All cats are living things ✓
Example: Some birds can fly. Pigeons are birds. Conclusion?
We can't definitely say pigeons can fly (some = not all).
Conclusion: Data inadequate / May or may not be true

🔐 Coding-Decoding
Ek pattern se letters/numbers encode hote hain. Pattern dhundho, phir decode karo!
Letter +1 Rule:
A→B, B→C, CAT→DBU
Reverse Alphabet:
A→Z, B→Y, Z→A
Number codes:
A=1,B=2,...,Z=26
Position shift:
+2, -3 etc.
Example: If CHAIR = EJCKT, then TABLE = ?
C+2=E, H+2=J, A+2=C, I+2=K, R+2=T (each letter +2 shift)
T+2=V, A+2=C, B+2=D, L+2=N, E+2=G →
