Blood Relation Practice Tests — Pick a Level and Start

Tap a level to see every test in it. Level 1 is set at real SSC CGL difficulty — start there the day you finish the concept. Level 2 is pitched above the exam, to push accuracy under pressure.

Blood relations is a chapter of one small family tree. Every question — a direct statement, a man pointing at a photograph, a woman introducing someone, a coded line such as P + Q × R, or a puzzle about six family members — describes a few links between people. Draw those links once, generation by generation, and the asked relation can be read straight off the tree.

Marks are lost in three places. The first is assuming a gender — a name, a profession or the word ‘child’ does not tell you whether a person is male or female, and ‘cannot be determined’ is often the right answer. The second is mixing up the two sides of the family — a father’s brother and a mother’s brother are both ‘uncle’ in English but chacha and mama in Hindi, and SSC asks for the side. The third is reading a pointing sentence from the front — start from the speaker’s end and work backwards instead.

How Many Blood Relation Questions Are Asked in SSC CGL?

Blood relations gives one question in a typical Tier I shift, sometimes two, and a few more in Tier II Paper I. It is one of the surest marks in reasoning — a well-drawn tree answers it in under a minute.

The first three forms are seen most often in SSC CGL papers; the rest appear in CGL, CHSL and MTS shifts and in Tier II. Practise all of them so no format surprises you.

What You Will Practice in the Blood Relations Chapter

Family-tree chains

• Short and long direct chains — two links up to six — across three and four generations
• In-law steps: father-in-law, mother-in-law, brother-in-law, sister-in-law, son-in-law and daughter-in-law
• Paternal versus maternal side — father’s brother or mother’s brother, father’s sister or mother’s sister, and the cousins on each side
• Generation gaps, the relation between two derived people, and reverse relations (if A is B’s nephew, B is A’s …)

Pointing, introducing and ‘only’-clauses

• Pointing at a person or a photograph, with one, two or three nested possessives
• Introducing someone — ‘her mother is the only daughter of my mother’
• Self-reference clauses — ‘my father’s only son’, ‘my mother’s only daughter’
• Speaker–listener chains — ‘your mother is the sister of my father’

Coded relations and puzzles

• Symbol codes (+, −, ×, ÷, $, #) with three or four people, and long expressions with six or seven
• Which expression means the given relation, which statement is (NOT) correct, and the missing symbol
• Digit and word codes — ‘P 3 Q’, ‘P ka Q’
• Family paragraphs, married-couple puzzles, age order, counting members, and statement sufficiency

Rules worth knowing by heart

Draw the tree before you look at the options — the options are made from the relations you get by misreading one link.

The three mistakes that cost the most marks

• Assuming a gender. ‘A is the child of B’ says nothing about A — wait for a word like son, wife or brother.
• Taking the wrong side of the family. A mother’s brother is mama, not chacha; a father’s sister’s son is a phupera bhai, not a mamera bhai.
• Assuming sibling means the same gender. A is the sibling of B and B is the brother of C — A can still be a sister.

How to Prepare Blood Relations for SSC CGL

1. Learn the relation names on both sides. Chacha, tau and bua on the father’s side; mama and mausi on the mother’s side; and the six in-law terms. Most wrong options are the right person on the wrong side.
2. Draw the tree every time. Generations on separate rows, + and − for gender, a double line for couples — it takes ten seconds and removes guesswork.
3. Mark a gender only when it is proved. Leave a question mark beside a person whose gender is not given, and check it before you choose.
4. Work pointing sentences backwards. Begin at ‘my’, replace each possessive with the person it names, and the chain shrinks to one link.
5. For coded relations, decode one pair at a time. Write each pair as a link on the tree as you go, then read the asked relation from the first person to the last.
6. Do Level 1 untimed first, then with the 15-minute clock. Move to Level 2 once Level 1 is steady, and then check yourself on a previous year paper.
