Practice Venn Diagram questions covering relationships between classes such as doctors, teachers, and parents, syllogism-style set logic, and identifying the correct diagram for a given group of items.
Question 1

Explanation
Aeroplane and Ship are different from each other (their circles do not overlap), but some passengers travel by aeroplane and some travel by ship, so the Passengers circle overlaps both. This is the chain of three overlapping circles in diagram C.
Question 2
Which of the following diagrams indicates the best relation between Income, Salary and Interest?

Explanation
Salary and Interest are different from each other, but both of them are parts of Income. So two separate circles lie inside one larger circle, as in diagram A.
Question 3
Which of the following diagrams indicates the best relation between Men, Fathers and Doctors?

Explanation
All fathers are men, so the Fathers circle lies inside the Men circle. Some fathers and some men may be doctors, so the Doctors circle overlaps both the Fathers circle and the Men circle (and also extends outside Men, since not all doctors are men). This is diagram B.
Question 4
Which of the following diagrams indicates the best relation between Hospital, Medicines and Doctors?
