CUET PG 2024 — Reasoning PYQ

1. Generations ka Mapping

Generation 1 (Grandparents):

• D (Husband) and H (Wife) ek couple hain.

  $$D(+)⟺H(-)$$

• D, G ka father hai aur A ka grandfather hai.

Generation 2 (Parents):

• G (Husband), D aur H ka beta hai.

• L (Wife), G ki patni hai ($G⟺L$).

• Q, D ki beti hai. Iska matlab Q, G ki behen hai.

• P, H ki beti hai. Iska matlab P bhi G aur Q ki behen hai.

  $$\text{Siblings: }G(+),Q(-),P(-)$$

Generation 3 (Children):

• A, G ka bachha hai (kyunki D, A ka grandfather hai aur G, D ka beta hai).

• K, A ki mother (L) ki sister ka beta hai.

2. Relationship Equation

Humein P aur Q ke beech ka rishta nikaalna hai.

• D aur H pati-patni hain ($D=\text{Father}$, $H=\text{Mother}$).

• Q, D ki beti hai: $Q\in \text{Children of }(D,H)$.

• P, H ki beti hai: $P\in \text{Children of }(D,H)$.

Chunki P aur Q dono ek hi parents (D aur H) ki betiyan hain:

Final Answer:

P, Q ki behen (Sister) hai.
