Deductive reasoning test: question types, worked examples and how to prepare

By Pratham Ranjan·10 min read·

A deductive reasoning test gives you a set of rules or statements and asks what must be true as a result. Answers have to follow from the information given, not from your own knowledge or a reasonable guess. Graduate employers use these tests to screen for clear, careful thinking under time pressure. The questions fall into five types, and nearly every mistake comes from one of three traps. If your invitation names an SHL test, also read our SHL deductive reasoning guide; for the wider family of tests, see logical reasoning tests.

TL;DRthe 30-second version
  • Deductive = from given rules to a conclusion that must be true.
  • Five question types: syllogisms, ordering, scheduling, if-then rules, "which conclusion follows".
  • Top traps: outside knowledge, reading "some" as "all", and reversing if-then rules.
  • Drawing a quick grid or line beats holding rules in your head.
  • SHL, Watson Glaser and Cappfinity all run deductive-style questions in different formats.
Definition
A deductive reasoning test is a timed aptitude test in which candidates apply given rules or premises to reach conclusions that are logically certain, using only the information provided.
  • The right answer is guaranteed by the rules. If it's only likely, it's wrong.
  • Most tests are 15–25 minutes and get harder as you go, or adapt to your answers.
  • You need no maths or specialist knowledge, only careful reading and a method.
  • It's different from inductive reasoning, where you spot a pattern in shapes or sequences.

The five types of deductive reasoning question

1. Syllogisms

Two or more statements, then a conclusion to judge. "All analysts use Excel. Some Excel users work in London. Therefore some analysts work in London." Does that follow? No. The London Excel users might not be analysts. Syllogisms test whether you can keep "all" and "some" straight.

2. Ordering and ranking

"Ana finished before Ben. Chris finished after Ben but before Dee." Who finished third? Draw a line and place each person as you read. Ana, Ben, Chris, Dee: Chris is third.

3. Scheduling and allocation

People, meetings or tasks must fit into slots under several constraints. This is the heart of SHL Verify Interactive Deductive, where you drag items into a timetable. A grid with rows for people and columns for slots turns a hard question into a quick one.

4. Conditional (if-then) rules

"If the project is approved, the team grows." If the team didn't grow, what follows? The project wasn't approved. But if the team grew, you can't conclude the project was approved, because something else might have caused it. Reversing if-then rules is the most common mistake on these tests.

5. "Which conclusion follows?"

A short passage and several conclusions; pick the one that must be true, or judge each as true, false or uncertain. Watson Glaser's deduction section works this way. Anything that needs an assumption is out.

The three traps that cost the most marks

Trap 1: using outside knowledge
If a statement says "all fish can fly", then for this question, all fish can fly. Answers that sound sensible in real life but don't follow from the rules are the most common wrong options.
Trap 2: reading "some" as "all" (or "most")
"Some" means at least one, possibly all. It never tells you about the rest. Underline quantifiers as you read.
Trap 3: reversing if-then rules
"If A, then B" lets you conclude "not B, so not A". It never lets you conclude "B, so A". Test-setters put the reversed version in almost every conditional question.

How to prepare in a week

  1. Day 1: find out the exact test from your invitation. Learn the five question types above.
  2. Day 2: syllogisms and quantifiers. Practise until "some" and "all" are automatic.
  3. Day 3: if-then rules. Write out the valid and invalid directions for every rule you meet.
  4. Day 4: ordering and scheduling. Draw a grid for every question, even easy ones.
  5. Day 5–6: timed sets in your test's format. Label each mistake by trap.
  6. Day 7: one full timed test, then rest.

Frequently asked questions

What is a deductive reasoning test?

A timed test where you're given rules or statements and must work out what must be true from them, without using outside knowledge. Common formats are syllogisms (if all A are B…), ordering and scheduling puzzles, and 'which conclusion follows' questions.

What is the difference between deductive and inductive reasoning?

Deductive reasoning goes from given rules to a conclusion that must be true. Inductive reasoning goes from examples to a likely rule, as in shape-sequence tests. In a deductive test, a correct answer is guaranteed by the rules; in an inductive test, you're spotting a pattern.

Which companies use deductive reasoning tests?

Many graduate employers in banking, consulting, law and professional services use them, often as part of a wider battery. SHL's deductive tests (including Verify Interactive Deductive and the Verify G+ general ability test) are among the most common; law firms often use the Watson Glaser test, which has its own deduction section.

How do I get better at deductive reasoning tests?

Learn the handful of question types, practise drawing the rules as a quick diagram or grid, and train yourself to use only the information given. Then practise against a timer. Most lost marks come from bringing in outside assumptions or misreading 'some' and 'all'.

Is a deductive reasoning test the same as a logical reasoning test?

Not exactly. 'Logical reasoning' is an umbrella term that employers use for deductive tests, inductive (pattern) tests, or both. Check your invitation: if it mentions rules, conclusions or scheduling, it's deductive; if it shows shape sequences, it's inductive.

Can I use a calculator or paper in a deductive reasoning test?

Rough paper is usually allowed and very useful for drawing grids. Calculators are rarely needed because the questions are about logic, not arithmetic. Check your invitation for the employer's rules.
