1. Mixed Pattern Concept

In advanced questions, different rules are applied together:

• Letter shift + reverse
• Position change + number coding
• Word rearrangement

---

2. Pattern Identification Trick

Check first → Middle → Last letters Find pattern → Apply to full word

---

3. Example (Mixed Shift)

CAT → DBV

C → D (+1)
A → B (+1)
T → V (+2)

👉 Pattern is not uniform → check carefully

---

4. Example (Reverse Pattern)

ABC → ZYX

A ↔ Z
B ↔ Y
C ↔ X

👉 Opposite alphabet logic

---

5. Example (Position Coding)

CAT → 3-1-20

C=3, A=1, T=20

👉 Direct alphabet positions

---

6. Common Mistakes

• Assuming same pattern for all letters ❌
• Ignoring reverse logic ❌
• Not checking position-based coding ❌

---

7. Topper Tip

If pattern is not clear, try reverse or position logic. Always test 2–3 possibilities quickly.

---

8. Quick Practice

DOG → FQL
Then CAT → ?

D→F (+2)
O→Q (+2)
G→L (+5)

C→E (+2)
A→C (+2)
T→Y (+5)
Answer: ECY ✔
