Sample questions

Sample Easy question 1

Which arrangement best represents 'Men', 'Doctors' and 'Women'?

  1. Three separate circles with no overlap between any of them
  2. Two non-overlapping circles (Men, Women), each partially overlapped by a third circle (Doctors)
  3. One single circle that represents all three groups together
  4. Doctors circle drawn completely inside the Men circle only
Show answer

Answer: B. Doctors can be either men or women, so the Doctors circle overlaps both the Men and Women circles, which don't overlap each other.

Sample Easy question 2

A survey shows some people like only Tea, some like only Coffee, and some like both. Which diagram best represents this?

  1. Two circles overlapping partially
  2. One circle drawn completely inside another circle
  3. A single circle that represents both groups
  4. Two circles that are completely separate from each other
Show answer

Answer: A. The overlapping region represents people who like both tea and coffee.

Sample Easy question 3

Which arrangement best fits 'Vehicles', 'Cars' and 'Toyota' (a car brand)?

  1. Toyota circle inside Cars circle, which is inside Vehicles circle
  2. Toyota and Cars circles are identical, separate from the Vehicles circle
  3. Vehicles circle inside the Cars circle, and Toyota outside both
  4. Three separate circles that do not overlap or lie inside one another
Show answer

Answer: A. Toyota is a subset of Cars, which is a subset of Vehicles, so the circles are nested inside one another.

Sample Medium question 4

Which diagram best represents the relationship between Teachers, Females, and Doctors?

  1. One circle inside another
  2. All separate circles
  3. Three overlapping circles
  4. Two overlapping, one separate
Show answer

Answer: C. A person can be a teacher, a female, and a doctor simultaneously, so all three groups overlap.

Sample Medium question 5

What is the relationship between 'Animals', 'Dogs' and 'Cats'?

  1. Animals circle inside the Dogs circle and the Cats circle
  2. Two small non-overlapping circles (Dogs, Cats) inside a larger circle (Animals)
  3. All the three circles are identical to each other
  4. Dogs circle inside the Cats circle, which is inside Animals
Show answer

Answer: B. Both Dogs and Cats are subsets of Animals, but a dog cannot be a cat, so their circles don't overlap.

Sample Medium question 6

If some students are both athletes and musicians, which diagram represents 'Students', 'Athletes' and 'Musicians'?

  1. Three circles all overlapping in the middle
  2. Three completely separate circles
  3. Athletes circle inside Musicians circle only
  4. Students circle with no overlap with the other two
Show answer

Answer: A. Since some students are also athletes and musicians, all three circles overlap.
