Show answer & explanation
Correct answer: A
To determine the total number of persons who have applied for more than one post, we need to sum the numbers located in the overlapping sections of the Venn diagram.
Analysis of Overlapping Regions
Teacher and Engineer overlap (exclusive of Accountant): 4
Teacher and Accountant overlap (exclusive of Engineer): 6
Engineer and Accountant overlap (exclusive of Teacher): 8
Intersection of all three posts (Teacher, Engineer, and Accountant): 3
These regions represent everyone who applied for at least two posts.
Calculation
Sum = 4 + 6 + 8 + 3 = 21
