Logic Deduction: Practice Set 2

Logic Deduction: Practice Set 2 is a second round of practice on the reasoning puzzles used in 11+ verbal reasoning papers, building on ordering statements into a single chain with harder puzzles that use four or five people, statements given out of order, and puzzles that match people to a single attribute, such as a pet or an instrument, rather than only ranking them by height or age.

Before you start

Make sure you're comfortable with these topics first:

Method

  1. Read every statement and decide whether it describes an order (taller than, older than, faster than) or a match (this specific person owns, plays or likes this specific thing).
  2. For an order puzzle, rewrite every statement as 'X above Y' using one consistent direction, then find the names that repeat across two statements to link the separate chains into one full line.
  3. Statements are not always given in a useful order, so build the chain from whichever statement links two people you already know about first, then attach the outer people afterwards.
  4. For a matching puzzle, draw a small table with a row for each person and a column for each possible attribute, and cross off any combination a statement rules out.
  5. When one row of the table has only one attribute left uncrossed, that attribute belongs to that person; use this newly confirmed fact to cross the same attribute off every other row.
  6. Once the table or chain is fully complete, reread the question to check exactly what is being asked before giving your final answer.

Worked example

Ali, Beth and Cara each own exactly one pet: a cat, a dog or a fish. Beth does not own the cat or the fish. Ali does not own the fish. Which pet does Cara own?

  1. Draw a table with rows for Ali, Beth and Cara and columns for cat, dog and fish.
  2. Beth does not own the cat or the fish, so cross those off Beth's row, leaving Beth with only dog possible.
  3. Since Beth must own the dog, cross dog off Ali's row and Cara's row.
  4. Ali does not own the fish, and dog is already crossed off Ali's row, so Ali's only remaining option is cat.
  5. With Ali confirmed as cat and Beth as dog, the only pet left for Cara is fish. Final answer: Cara owns the fish.

Answer: Seat 3 - if Ben sat in seat 2, Cleo would be in seat 3 and Ada would be forced into seat 1, which is not allowed, so Ben must be in seat 1, Cleo in seat 2, and Ada in seat 3.
