Logical Reasoning Test
Read a short set of premises and choose the conclusion that must be true. The questions are purely verbal and deductive — syllogisms, if-then reasoning and simple logic puzzles — so no maths or prior knowledge is needed. Fifteen questions give your score, accuracy and average time.

Which conclusion must be true?About the Logical Reasoning Test
Deductive logic asks what follows with certainty from what you are told — not what is merely likely. Each question gives one or more premises and four candidate conclusions; exactly one must be true if the premises hold. The reasoning is verbal, covering categorical syllogisms (all / no / some), conditional rules (if P then Q), disjunctive choices and the transitive ordering of items.
Answer with a click or the keys 1 to 4. A few questions deliberately give too little information, so the correct answer is that nothing certain can be concluded. Your result is the number correct out of 15, with a percentage and your average time per question.
About
The Logical Reasoning Test presents fifteen deductive questions that cover categorical syllogisms, conditional if-then statements and compact logic puzzles. Each item requires you to evaluate premises, identify valid conclusions and spot common fallacies such as affirming the consequent or illicit conversion. The test runs in the browser with no time limit, so you can work through each argument at your own pace and review the rationale after submitting your answers.
How your result is scored
Your raw score is the number of correctly answered questions out of fifteen. After completion you receive a brief breakdown showing which question types — syllogisms, conditionals or puzzles — contributed most to your total, helping you see where your reasoning is strongest.
Tips to improve
- Translate each premise into a simple diagram or symbolic form before choosing an answer.
- Watch for quantifier shifts — "all" versus "some" — that change the logical force of a statement.
- Test the contrapositive of every conditional to verify whether the conclusion follows.
- Eliminate answer choices that introduce information not contained in the premises.
- Re-read the puzzle scenario after a short pause; fresh eyes often catch hidden contradictions.
