CUET PG 2026 — Reasoning PYQ

To solve this, we can use a Venn diagram approach:

1. Statement I ("All windows are door"): This means the circle for "Windows" ($W$) is entirely inside the circle for "Doors" ($D$).

   • $W\subset D$

2. Statement II ("No door is a wall"): This means the circle for "Doors" ($D$) and the circle for "Walls" ($L$) have no intersection. They are completely separate.

   • $D\cap L=\varnothing$

Evaluating Conclusions:

• Conclusion I ("No window is wall"): Since all windows are inside the "Door" circle, and the "Door" circle cannot touch the "Wall" circle, it is physically impossible for any "Window" to be a "Wall."

  • Conclusion I is Correct.

• Conclusion II ("No wall is door"): Statement II says "No door is a wall." In logic, "No $A$ is $B$" always implies "No $B$ is $A$." Therefore, if no door is a wall, then no wall can be a door.

  • Conclusion II is Correct.

Final Answer:

Since both conclusions follow logically from the statements, the correct option is (d) Both I and II.
