Concept Notes
Comparison Puzzle— Rules & Concept
💡
Core Concept
Read this first — the foundation of the topic
→Core Concept
Comparison puzzles work by giving you clues like 'A is taller than B' or 'C scored less than D'. You must use these clues to arrange all items in a line (ascending or descending order). Think of it like solving a chain where each link connects two items
💡Key Rules
Read all statements carefully before starting.
2
→Use symbols to track relationships
> (greater), < (less), = (equal).
3. Combine individual statements to create a complete chain.
4. Check your final answer against all given statements.
5. Watch for indirect comparisons — sometimes you must link multiple statements together.
🔢
Formula Block
Memorise — at least one formula appears in every paper
If A > B and B > C, then A > C (Transitive Property). This is the backbone of all comparison puzzles.
📊
Exam Patterns
What examiners ask — read before attempting PYQs
SSC CGL typically asks:
- Who is the tallest/shortest/oldest/youngest?
- Arrange in increasing/decreasing order.
- Find positions of specific people in the arranged order.
- Handle 5-7 people with 4-6 comparative statements.
Shortcut/Trick:
Draw a simple line or arrow diagram. Write names and connect them with arrows showing the direction of comparison. This visual method solves 90% of puzzles faster than written logic.

Worked Example
Solve this step-by-step before moving on
1
Step 1
Write statements using symbols.
Raj > Priya ... (1)
Anu > Raj ... (2)
Sita < Priya ... (3)
Mohan > Anu ... (4)
2
Step 2
Link the chain.
From (1): Raj > Priya
From (2): Anu > Raj, so Anu > Raj > Priya
From (4): Mohan > Anu, so Mohan > Anu > Raj > Priya
From (3): Sita < Priya, so Sita is even smaller
3
Step 3
Final order from tallest to shortest.
Mohan > Anu > Raj > Priya > Sita
Answer: Mohan is the tallest.
Common Mistake:
Students often ignore indirect relationships. If A > B and C > A, they sometimes forget that C > B as well. Always trace the complete chain before answering. Also, don't assume anything not stated in the problem.
Key Points to Remember
Comparison puzzles require you to arrange items in order using given statements about relationships.
Use the transitive property: if A > B and B > C, then definitely A > C.
Always draw a visual line or arrow diagram to track relationships clearly.
Read every statement carefully; indirect comparisons are often hidden in the clues.
Check your final answer by verifying it satisfies all given statements.
Common properties compared in SSC CGL: age, height, weight, marks, salary, and speed.
Exam-Specific Tips
Comparison puzzles in SSC CGL typically involve 5-7 persons and 4-6 comparative statements.
The transitive property (if A > B and B > C, then A > C) is the mathematical foundation of all comparison puzzles.
Most SSC CGL comparison puzzles ask for the maximum or minimum person in a specific property.
Five friends—Aman, Bhavna, Chetan, Diya, and Esha—are sitting in a row facing North. Bhavna sits immediately to the right of Aman. Chetan sits to the right of Diya. Esha sits at one end. Diya is not at either end. Who sits second from the left?
Practice 2medium
Five friends — Arjun, Bhanu, Chetan, Deepak, and Eshan — have different heights. Arjun is taller than Bhanu but shorter than Chetan. Deepak is shorter than Bhanu. Eshan is taller than Chetan. Who is the second tallest among them?
60-Second Revision — Comparison Puzzle
Remember: Always create a visual chain or arrow diagram; it reduces mistakes and saves time.
Formula: Use transitive property A > B and B > C means A > C without exception.
Trap: Don't ignore indirect statements; link all clues together before concluding.
Method: Read statement → Convert to symbol → Link the chain → Verify answer against all statements.
Pattern: SSC asks 'who is tallest/shortest' or 'arrange in order' — both solved by the same chain method.
Common error: Assuming relationships not stated in the problem — stick only to given information.
Time saving: Solve in 60-90 seconds by drawing arrows instead of writing explanations.
