What is the total number of persons who have applied for more than one post?

Accepted Answer

The given diagram represents a Venn diagram with three sets: Teacher, Engineer, and Accountant. The numbers in the overlapping regions represent the number of persons who have applied for multiple posts.

We need to find the total number of persons who have applied for more than one post, i.e., those in the intersections of the sets.

From the diagram:
- 4 persons applied for Teacher and Engineer only
- 3 persons applied for Engineer and Accountant only
- 6 persons applied for Teacher and Accountant only
- 8 persons applied for all three posts (Teacher, Engineer, Accountant)

Total number of persons who applied for more than one post = 4 + 3 + 6 + 8 = 21
