Venn Diagram Aptitude MCQ Questions with Answers Set 01

Answer: (c) G

Explanation:
1. Tall girls who swim lie inside the square, the circle and the rectangle: regions G and H.
2. They must not play tennis, so the region must be outside the triangle; H lies inside the triangle.
3. Only G remains.

Teacher's Note:
1. Translate each condition into 'inside' or 'outside' a shape, then keep only the region that satisfies all of them.
2. Words like 'but not', 'neither...nor' and 'only' tell you which shapes the region must lie outside.

Answer: (d) None

Explanation:
1. Girls who swim and play tennis lie in the region common to the square, rectangle and triangle: only H.
2. They must not be tall, so the region must be outside the circle, but H lies inside the circle.
3. No region fits, so the answer is None.

Teacher's Note:
1. Translate each condition into 'inside' or 'outside' a shape, then keep only the region that satisfies all of them.
2. Words like 'but not', 'neither...nor' and 'only' tell you which shapes the region must lie outside.

Answer: (b) D

Explanation:
1. Tall girls lie inside both the square and the circle: C, D, G and H.
2. Remove regions inside the rectangle (G, H) and inside the triangle (C, H).
3. Only D is left.

Answer: (c) K

Explanation:
1. Tall persons lie inside the circle: C, D, G, H, I, J, K.
2. Gents are outside the square and non-tennis players are outside the triangle: this leaves J and K.
3. They must also be swimmers (inside the rectangle), so the answer is K.
