IGDTUW 2025 — Reasoning PYQ

To solve this problem, we need to carefully interpret the Venn diagram based on the given categories:

1. Definitions:

   • Circle ($C$): Ladies

   • Triangle ($T$): Teachers

   • Rectangle ($R$): Unmarried persons

2. Required Category:

   • We need to find "Married ladies who are teachers."

   • This means the person must be a Lady (inside the circle) and a Teacher (inside the triangle), but NOT Unmarried (outside the rectangle).

3. Analyzing the Venn Diagram:

   • The intersection of the circle and the triangle includes two sections: one with the number 3 and one with the number 9.

   • The number 9 lies inside the rectangle (which represents unmarried persons), so it represents "Unmarried lady teachers."

   • The number 3 lies inside the circle and the triangle, but it is outside the rectangle.

Since the rectangle represents "unmarried persons," the area outside the rectangle represents "married persons." Therefore, the value 3 represents the ladies who are teachers and are not in the rectangle (meaning they are married).

$$Numberofmarriedladyteachers=3$$

The correct option is (b) 3.
