You are given information about positions, rankings, or arrangements. Your job is to determine the exact order or find specific positions of elements in that arrangement
💡Key Rules
Always work systematically from left to right or top to bottom. When multiple conditions are given, satisfy all conditions simultaneously. Pay attention to words like 'between', 'immediately', 'adjacent', 'next to', and 'opposite'
→Types of Questions
Linear arrangements (single row), circular arrangements, and ranking based on performance, height, weight, or age. SSC CGL frequently asks about finding positions, counting people between two positions, or determining who sits where
⚡Shortcut Technique 1
Use the 'Anchor Method'. Find the most restrictive condition first and use it as your starting point. This saves time and reduces errors.

Worked Example
Solve this step-by-step before moving on
1
Step 1
D sits at one end. Let's place D at the left end: D _ _ _ _
2
Step 2
A sits two places to the left of E. This means there's exactly one person between A and E. Possible positions: A_E or positions 2 and 4.
3
Step 3
Since D is at position 1, A can be at position 2 and E at position 4: D A _ E _
4
Step 4
B sits immediately to the right of C. The remaining positions are 3 and 5. So C must be at position 3 and B at position 5.
Final arrangement: D A C E B
Verification: A is two places left of E ✓, B is immediately right of C ✓, D is at one end ✓
Shortcut Technique 2: Use the 'Elimination Method' for ranking questions. When given partial information about ranks, eliminate impossible positions systematically.
Common Mistakes: Students often confuse 'left' and 'right' directions. Always maintain consistent orientation. Another mistake is not checking if the final arrangement satisfies ALL given conditions. Many students also misinterpret 'between' (which excludes endpoints) and 'among' (which can include endpoints).

Exam Patterns
What examiners ask — read before attempting PYQs
SSC CGL typically asks 1-2 questions on this topic. Questions usually involve 5-8 people or objects. Linear arrangements are more common than circular ones. The difficulty level is moderate, and these questions are scoring if approached systematically.
