Are you working hard day and night to crack the SSC MTS exam and get a secure central government job? We know that for many students, the Reasoning section is the key to scoring high marks. However, there is one topic that makes many students scratch their heads: Blood Relations. When a question says, “A’s father’s brother’s daughter is B,” your brain might get completely confused. You might start thinking about your own uncles and aunts to find the answer. But the best part is you do not need to guess anything. If you know how to draw a simple “Family Tree” on paper, you can solve any question in just 10 seconds. In this blog, we have explained this topic in the simplest way possible. We have also provided exam-level questions for each type that you can practice right now.
What is Blood Relation?
In the SSC MTS exam, Blood Relation simply means finding the family connection between two people based on the clues given in the question. You do not need to read thick books for this. You just need to learn how to draw a family tree. Here are the only 3 rules you need to know:
- Generations go Up and Down: Your grandparents are at the top, your parents are below them, you and your brothers/sisters are in the middle, and your children are at the bottom.
- Gender Signs: Always use a “Plus (+)” sign or a “Box” for males (boys/men). Use a “Minus (-)” sign or a “Circle” for females (girls/women).
- Marriage and Siblings: Use a double line (=) between husband and wife. Use a single line (-) between brothers and sisters.
The 3 Main Subjects (Types) of Blood Relation in SSC MTS:
- Pointing or Indicating Form: Where someone points to a photo and tells a relation.
- Family Tree or Puzzle Form: Where direct relations like “A is the brother of B” are given.
- Coded Form: Where symbols like +, -, *, % are used to show relations.
Practice: Top Exam-Level Blood Relation Questions
Now that you know the basics, it is time to test your brain. Below, we have provided top exam-level questions divided into three parts. Grab a pen, draw the family tree, and try to solve them.
Q1. Pointing to a photograph, a man said, “He is the son of the only son of my grandfather.” How is the man in the photograph related to the man speaking?
(A) Brother
(B) Son
(C) Uncle
(D) Nephew
Answer: (B) Son
Logic: “Only son of my grandfather” means the speaker’s own father. The “son of the speaker’s father” is the speaker himself. But since he is pointing to a boy, it can be his brother, or if the speaker is the only son, it is his own son. Let’s assume the speaker is the only son. So, the boy is his son.
Q2. Pointing to a woman, Rahul said, “Her mother is the only daughter of my mother.” How is Rahul related to the woman?
(A) Father
(B) Uncle (Maternal)
(C) Brother
(D) Husband
Answer: (B) Uncle (Maternal)
Logic: “Only daughter of my mother” means Rahul’s sister. So, the woman is the daughter of Rahul’s sister. This makes Rahul her maternal uncle or Mama.
Q3. A woman introduces a man as the son of the brother of her mother. How is the man related to the woman?
(A) Nephew

(A) Mother
(B) Grandmother
(C) Sister
(D) Aunt
Answer: (A) Mother
Logic: “Only daughter of my mother” is the woman herself. So, she is the mother of the man.

(A) Grandson

(C) Son-in-law
(D) Nephew
Answer: (A) Grandson
Logic: Man’s son’s sister is the man’s daughter. The man’s daughter is the woman’s mother-in-law. This means the man’s daughter is the mother of the woman’s husband. So, the husband is the grandson of the man.
Q9. Showing a man on the screen, a girl said, “He is the brother of my uncle’s daughter.” How is the man related to the girl?
(A) Brother
(B) Cousin
(C) Nephew

(A) Grandfather
(B) Father

5 Simple Tips to Prepare Blood Relations for SSC MTS
You do not need to be a genius to solve these questions. Just keep a cool head and follow these 5 easy tips:
- Never Guess Gender by Name: Just because a name is “Kiran” or “Sonu”, do not assume they are male or female. Always look for words like “brother,” “sister,” “his,” or “her” to confirm the gender.
- Draw the Family Tree: Never try to solve family puzzles in your head. Always draw the tree on your rough sheet. Put older generations on top and use plus (+) for males and minus (-) for females.
- Break Down Pointing Questions: For questions starting with “Pointing to a man…”, break the sentence at the word “my”. Solve the speaker’s side first, and then connect it to the person they are pointing at.
- Use the “Self” Trick: Sometimes, the easiest way to solve a pointing question is to put yourself in that situation. Imagine your own uncle or aunt. It helps you find the answer faster!
- Practice Previous Year Papers: SSC MTS repeats the pattern of Reasoning questions every year. Solve the previous year’s blood relation questions. You will see that they are very easy and highly repetitive.

FAQs: Blood Relation Questions for SSC MTS Exam
No, not at all! The reasoning section in the SSC MTS exam is of 10th-pass level. The blood relation questions are very basic and can be solved easily if you draw a simple diagram.
You can comfortably expect 1 to 2 direct questions from Blood Relations in the Reasoning ability section.
Absolutely not! Blood relations is a purely logical topic. There are no math formulas here. You just need to know basic family connections like uncle, aunt, niece, and nephew.
If the question says “A is the child of B,” you cannot assume A is a boy or a girl. In such cases, if the options ask for the exact relation, look for options like “Son or Daughter” or “Cannot be determined.”
