Question 6: In a company, Designers are represented by a circle, Marketers by a square, and Product Managers by a triangle in the Venn diagram below. Based on the figure, who is most represented in the company?

Solution: Product Managers with Design background are most represented in the company.

Explanation:

To determine who is most represented, look at the size and overlap of the shapes in the Venn diagram:

• The circle (Designers) shows all designers.
• The square (Marketers) shows all marketers.
• The overlapping area between the circle and square represents Designers with a Marketing background.
• The overlap between triangle (Product Managers) and circle (Designers) shows Product Managers with Design background.

The group with the largest section (largest area or most elements inside their shape) is the most represented in the company.

Question 7: In the following figure, the triangle represents teachers, the square represents musicians, and the circle represents athletes. Which part of the diagram represents the teachers who are musicians but not athletes?

Solution: Q

Explanation:

We want the area where triangle and square overlap, but excluding the part that also overlaps with the circle (athletes). This is the region inside both the triangle and square but outside the circle.

Question 8: In the given diagram, the rectangle represents doctors, the triangle represents surgeons, the circle represents researchers, and the square represents hospital staff.

Identify the region representing surgeons who are doctors but not researchers.

Solution: 12

Explanation:

We want surgeons who are doctors but not researchers, meaning the part inside both the rectangle and the triangle, but outside the circle.

So the correct region is the intersection of the,rectangle and triangle, excluding the circle that is 12.
