Introduction to Cousin

Prerequisites

Sibling relationships Parent-child relationships Grandparent relationships Understanding of generation levels

Why This Matters: Cousin problems appear in 1-2 questions in SSC CGL and Banking PO exams. They test understanding of extended family structures.

How to Solve Cousin Problems

Step 1: Identify the common ancestors shared by the two individuals.

Step 2: Determine the relationship between the parents of the two individuals.

Step 3: If parents are siblings, the individuals are first cousins.

Step 4: If grandparents are siblings, the individuals are second cousins.

Step 5: For 'once removed', there is a one-generation difference.

Step 6: Track the generation difference to determine 'removed' status.

Step 7: Answer with the correct cousin terminology.

Pro Strategy: Always find the common ancestors first. Count the number of generations from each person to the common ancestor. If the generation counts are equal, they are cousins of the same degree (first cousins = 2 generations up to common ancestor).

Example Problem

Example: A and B are brothers. C is the son of A. D is the daughter of B. How are C and D related? Solution: Step 1: A and B are siblings. Step 2: C is child of A, D is child of B. Step 3: Children of siblings are first cousins. Answer: First cousins.

Pro Tips & Tricks

First cousins: share grandparents (2 generations up).
Second cousins: share great-grandparents (3 generations up).
Third cousins: share great-great-grandparents (4 generations up).
Once removed: one generation difference.
Twice removed: two generations difference.
Children of siblings are first cousins.

Shortcut Methods to Solve Faster

Cousin degree = Generations to common ancestor - 1.

Removed = Difference in generations to common ancestor.

If parents are siblings → children are first cousins.

If grandparents are siblings → grandchildren are second cousins.

Common Mistakes to Avoid

Confusing first cousins with second cousins.

Not understanding 'removed' relationships.

Assuming cousins are always on the same generation.

Forgetting that cousins share grandparents, not parents.
