This video, part of the "CSAT MADE EASY | UPSC PRELIMS 2026 | PYQ SERIES 2014 - 25" series, focuses on Blood Relation questions for the UPSC CSAT exam (0:54).
Male: Square (1:11)
Female: Circle (1:24)
Siblings: Straight line (1:27)
Married couple: Curved line (1:34)

The video then proceeds to solve several past year questions (PYQs) related to blood relations:

2025 PYQ (example problem explanation): This problem introduces symbolic representations for relationships (e.g., A + B means A is the son of B) and asks to interpret a given expression (2:27). The instructor meticulously breaks down the expression P + R - Q to determine the relationship between P and Q, ultimately identifying Q as P's father (6:27-6:52).
2017 PYQ (family structure problem): This question involves six individuals with an equal number of males and females, and specific relationships are given. The goal is to deduce the family tree and identify the correct statement among the options (6:55). The solution builds the family tree, confirming A is the husband of D (11:16-11:46).
A Family of Two Generations (unspecified year): This problem features six members across two generations, with three males and three females, and two married couples. The instructor constructs the family hierarchy based on the clues, concluding that R is S's wife (12:25-17:50).
2022 PYQ (complex family relationships): This question presents six family members and their intricate relationships. The instructor diagrams the family structure, then uses the visual representation to evaluate given statements. The conclusion is that T is the granddaughter of Q, despite Q's gender being unknown, because the relationship is generational (18:07-23:07).
2025 PYQ (identifying 'definitely true' statements): The final problem asks to identify statements that are "definitely true" based on the given information. The instructor emphasizes checking for unknown genders which would make a statement not "definitely true" (23:23). Out of several statements, four are confirmed as definitely true (28:31-29:01).
