Bank Exam Reasoning – Inequality & Coding-Decoding (Concept + Practice)
Inequality and Coding-Decoding are scoring topics in bank exams. With proper understanding of patterns and logic, these can be solved quickly.
1. Inequality – Concept
Inequality compares values using symbols like greater than, less than, or equal to.
- > : Greater than
- < : Less than
- = : Equal
- ≥ : Greater than or equal to
- ≤ : Less than or equal to
Example:
A > B ≥ C > D → A > D (True)
2. Inequality – Rules
- Form a chain from given relations
- Check direction carefully
- If no connection, do not assume
3. Coding-Decoding – Concept
Coding-Decoding involves finding patterns in letters or numbers.
Example:
CAT → DBU
Pattern: Each letter +1
4. Types of Coding
- Letter shifting (A=1, B=2...)
- Reverse coding
- Number coding
- Pattern-based coding
Practice Questions
Q1 (Inequality):
A ≥ B > C ≥ D
→ A > D ?
Q2 (Inequality):
A > B
C > D
→ A > D ?
Q3 (Coding):
DOG → EPH
CAT → ?
Answers
Q1: True
Q2: Cannot be determined
Q3: DBU
Exam Strategy
- Solve inequality in 20–30 seconds
- Identify coding pattern quickly
- Skip confusing questions
