Sample questions

Sample Easy question 1

Which arrangement best represents 'Fruits', 'Mangoes' and 'Apples'?

  1. Two circles fully overlapping
  2. One big circle (Fruits) containing two separate, non-overlapping circles (Mangoes, Apples)
  3. Three separate circles with no overlap
  4. One circle only
Show answer

Answer: B. Mangoes and Apples are both distinct types of Fruits, so both are separate circles nested inside the Fruits circle.

Sample Medium question 2

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

  1. Two small non-overlapping circles (Dogs, Cats) inside a larger circle (Animals)
  2. Dogs circle inside Cats circle
  3. All three circles identical
  4. Animals circle inside Dogs circle
Show answer

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

Sample Hard question 3

Which diagram fits 'Mammals', 'Whales' and 'Fish' (whales are mammals, not fish)?

  1. Whales circle inside Mammals circle, completely separate from Fish circle
  2. Whales circle inside Fish circle
  3. Mammals and Fish circles are identical
  4. Whales circle overlapping both Mammals and Fish
Show answer

Answer: A. Since whales are mammals and never fish, the Whales circle sits entirely inside Mammals and apart from Fish.
