1. In a Venn diagram with two overlapping circles representing 'Doctors' and 'Women', what does the overlapping region represent?

  1. AWomen who are doctors
  2. BAll doctors
  3. CAll women
  4. DPeople who are neither doctors nor women
Show answer

Answer: A

The overlapping region of two circles in a Venn diagram represents elements common to both sets, i.e., women who are doctors.

2. In a Venn diagram, two circles representing 'Cats' and 'Dogs' are drawn as completely separate with no overlap. What does this correctly indicate?

  1. ANo animal can be both a cat and a dog
  2. BAll cats are dogs
  3. CAll dogs are cats
  4. DSome cats are dogs
Show answer

Answer: A

Two non-overlapping circles indicate that the two categories are mutually exclusive, meaning no member belongs to both.

3. In a Venn diagram of 'Football Players' and 'Tall People' with a partial overlap, what does the overlapping region represent?

  1. AFootball players who are also tall people
  2. BAll football players
  3. CAll tall people
  4. DPeople who are neither football players nor tall
Show answer

Answer: A

A partial overlap between two circles represents the subset of elements common to both categories — here, football players who are tall.

4. In a Venn diagram, Circle A represents 'Doctors', Circle B represents 'Men', and Circle C represents 'Married People'. Which region represents 'Married Male Doctors'?

  1. AThe region where all three circles A, B, and C overlap
  2. BThe region where only A and B overlap
  3. CThe region unique to circle A only
  4. DThe region where only B and C overlap
Show answer

Answer: B

'Married Male Doctors' must satisfy all three conditions (Doctor, Man, Married), so it corresponds to the central region where all three circles A, B, and C overlap.

5. In a Venn diagram, Circle A represents 'Teachers', Circle B represents 'Women', and Circle C represents 'Parents'. Which region represents 'Women who are Parents but not Teachers'?

  1. AThe region where B and C overlap but not A
  2. BThe region where A and B overlap but not C
  3. CThe region unique to B only
  4. DThe region where all three overlap
Show answer

Answer: A

'Women who are Parents but not Teachers' satisfies B and C but excludes A, so it corresponds to the overlap of B and C excluding the part shared with A.
