Introduction: Mastering Blood Relation Puzzles for Competitive Exams

In almost every competitive examination — whether it’s SSC CGL, UPSC CSAT, UPPSC, BPSC, or banking exams — one section that tests both logic and quick interpretation is Blood Relation reasoning.

These puzzles may look simple, but when mixed with indirect clues or multi-generation relationships, they become tricky. The aim of today’s puzzle is to help you analyze family-based relationships step-by-step and build logic visualization skills that are essential for high-scoring reasoning sections.

Welcome to Daily Reasoning Puzzle #2 – Blood Relation, part of our 30-day Daily Puzzle Series, designed to sharpen your problem-solving speed, pattern recognition, and logical accuracy for government exams.

Why Blood Relation Puzzles Are Important

Blood Relation questions test your analytical thinking, data interpretation, and family structure comprehension.

In government exams like SSC, UPSC, and Banking, these puzzles usually appear in two formats:

  1. Direct Statements: e.g., A is the brother of B. B is the father of C. How is A related to C?

  2. Coded/Complex Relationships: e.g., ‘A + B’ means A is the father of B; ‘A – B’ means A is the sister of B; Find how A is related to D if A + B – C × D.

How to Approach Blood Relation Puzzles

Here’s a 4-step process to solve any Blood Relation question quickly:

  1. Read carefully and identify all persons mentioned.

  2. Write down relationships in symbolic form.

    • Father = F, Mother = M, Brother = B, Sister = S, Wife = W, Husband = H, Son = So, Daughter = D.

  3. Visualize the family tree or draw a quick diagram.

  4. Work backward from the last clue to the first — that’s where the final relationship usually lies.

Pro Tip: Always consider gender clues before assuming any relationship. For example, “X is the wife of Y” immediately reveals both genders.

Daily Reasoning Puzzle #2: Blood Relation Problem

Let’s dive into today’s reasoning challenge 👇

🧠 Puzzle Statement

  1. A is the father of B.

  2. C is the mother of A.

  3. D is the brother of C.

  4. E is the son of D.

  5. F is the daughter of B.

Question:
How is E related to F?

Step-by-Step Solution

Let’s decode it line by line:

  1. A is the father of B → A → B (Father → Son/Daughter)

    • So, A (M) and B (Next Generation)

  2. C is the mother of A → C → A (Mother → Son)

    • So, C (Female, Mother of A)

  3. D is the brother of C → D (Male, Sibling of C)

    • Therefore, D is A’s maternal uncle.

  4. E is the son of D → D → E (Father → Son)

    • So, E is A’s cousin.

  5. F is the daughter of B → B → F (Parent → Daughter)

    • F is A’s granddaughter.

Now, to find E’s relation to F:

  • E is A’s cousin.

  • F is A’s granddaughter.

So, E is F’s maternal or paternal uncle (depending on B’s gender) — since B could be son or daughter, but in both cases, E is one generation elder than F and male.

✅ Final Answer: E is the uncle of F.

Diagrammatic Representation

Generation Person Relation
1 D & C Brother–Sister
2 A (Son of C), E (Son of D) Cousins
3 B (Child of A) Next Generation
4 F (Daughter of B) Granddaughter of A

So, visually:

D ── E (Son)
│
C ── A ── B ── F

👉 E is F’s Uncle.

Alternative Example Puzzles

Let’s practice a few more to strengthen the concept.

Puzzle 1:

Statement:
A is the son of B. B is the brother of C. C is the daughter of D.

Question: How is A related to D?

Solution:

  • A is B’s son.

  • B is C’s brother → C and B are siblings.

  • C is daughter of D → D is parent of both C and B.

So, A is D’s grandson. ✅

Puzzle 2:

Statement:
P is the father of Q. Q is the sister of R. R is the son of S.

Question: How is S related to P?

Solution:

  • Q and R are siblings → same parents.

  • Q’s father is P → R’s father is also P.

  • R is son of S → S is R’s mother.

Hence, S is P’s wife. ✅

Puzzle 3:

Statement:
‘A + B’ means A is the father of B.
‘A – B’ means A is the sister of B.
‘A × B’ means A is the brother of B.
‘A ÷ B’ means A is the mother of B.

If P + Q – R × S ÷ T, then how is R related to T?

Solution:
Start decoding:

  1. P + Q → P is father of Q.

  2. Q – R → Q is sister of R.

  3. R × S → R is brother of S.

  4. S ÷ T → S is mother of T.

Thus, R is maternal uncle of T. ✅

Common Tricks to Solve Blood Relation Questions Quickly

  1. Count generations:

    • Upward → Parents, Grandparents

    • Downward → Children, Grandchildren

  2. Gender deduction:

    • Look for clues like husband, wife, son, daughter, mother, father.

  3. Visual approach:

    • Always draw the family tree; avoid solving mentally during exams.

  4. Use symbols:

    • M = Male, F = Female, = for siblings, ↑ for parent, ↓ for child

  5. Work from bottom-up in complex statements.
