Worked practice questions
In a Venn diagram of 'Hindu, Indian, Parrot', Parrot is shown by
- Within the Indian circle only
- Within the Hindu circle only
- A separate circle outside the others
- Overlapping all three
Show answer and solution
Correct answer: C. A separate circle outside the others
1. Parrot is neither Hindu nor Indian (animals lack religion/ethnicity).
2. So a separate circle, no overlap.
3. Hence option A.

For 'Apple, Fruit, Vegetable', the diagram is
- All three overlap completely only
- Apple inside Vegetable; Fruit separate only
- Three separate circles only
- Apple inside Fruit; Vegetable separate
Show answer and solution
Correct answer: D. Apple inside Fruit; Vegetable separate
1. All apples are fruits, so Apple is inside Fruit.
2. No fruit is a vegetable (in botanical sense here).
3. Vegetable circle stays separate.
4. Hence option A.
