About Blood Relations MCQs

Chain questions link several people in a line, for example a son of one person who is the daughter of another, and ask for the relation between the first and last. Photograph and introduction questions use a single sentence such as "She is the only daughter of my wife's mother" and ask how the woman is related to the speaker.

Coded relation questions use symbols such as + and × to stand for husband, father or daughter, and ask you to decode an expression or find which expression shows a given relation. All three types depend on drawing a small family tree that shows generation and gender. They appear regularly in MDCAT, NTS, ISSB, SSC and bank exams, and a tidy diagram makes even long chains quick to solve.

Key facts to remember

Your father's or mother's brother is your uncle, and their children are your cousins.
Your mother's mother's husband is your maternal grandfather.
"The only daughter of my wife's mother" refers to the speaker's wife.
A person's gender cannot be assumed from a name; only words such as son, wife or brother fix it.
Your sibling's son is your nephew and your sibling's daughter is your niece.

How to prepare for Blood Relations MCQs

Draw a family tree with generations in rows, using + for male and − for female, and marriage as a horizontal double line.
Work backwards from the end of a sentence such as "my father's only brother's daughter".
Do not assume gender from names; if gender is not stated, "cannot be determined" may be the right answer.
In coded questions, decode each symbol into words before drawing anything.

Frequently asked questions
