Introduction to Diagram/Table

Diagram/Table problems present family relationships in a visual diagram format (using symbols like □ for male, ○ for female) or in a table listing relationships. You must interpret the visual or tabular data to answer questions about relationships between individuals.

Prerequisites

Understanding of family tree symbols (□=male, ○=female, =marriage, | parent-child) Ability to read hierarchical diagrams Basic blood relation terms Relationship reversal skills
Why This Matters: Diagram/Table problems appear in 1-2 questions in SSC CGL and Banking PO exams. They test visual interpretation and data extraction skills.

How to Solve Diagram/Table Problems

1

Step 1: Familiarize yourself with the diagram symbols (usually provided).

2

Step 2: Identify all individuals in the diagram (each represented by a symbol).

3

Step 3: Note the generational levels (typically top to bottom).

4

Step 4: Trace marriage connections (horizontal lines).

5

Step 5: Trace parent-child connections (vertical lines).

6

Step 6: For each question, locate the two individuals and trace the path between them.

7

Step 7: Express the relationship using appropriate family terms.

Pro Strategy: Start from the oldest generation and work downward. Identify all marriage connections first, then parent-child relationships. Use the diagram as a map—trace paths between individuals to find relationships.

Example Problem

Example: In a family tree diagram, A and B are connected by a horizontal line (marriage). A has a vertical line down to C. B has a vertical line down to D. How is C related to D? Solution: Step 1: A and B are married. Step 2: A is parent of C. Step 3: B is parent of D. Step 4: C and D share parents A and B. Step 5: Therefore, C and D are siblings. Answer: Siblings.

Pro Tips & Tricks

  • Horizontal lines = marriage/spouse.
  • Vertical lines = parent-child.
  • Siblings share at least one parent.
  • Same horizontal level usually indicates same generation.
  • Watch for half-siblings (share one parent) vs full siblings (share both).
  • The number of vertical steps indicates generational distance.

Shortcut Methods to Solve Faster

Same parent → siblings.
Parent of parent → grandparent.
Child of sibling → nephew/niece.
Sibling of parent → aunt/uncle.

Common Mistakes to Avoid

Misreading the diagram symbols.
Confusing marriage lines with parent-child lines.
Not tracking multiple marriages correctly.
Assuming all children belong to both parents in a marriage.
