01
Find the conclusion that must be true
A conclusion can sound plausible without following from the rules. Distinguish a required consequence from one possible arrangement or an unsupported reversal.
Check the order
Distinguish a compulsory position from an arrangement that merely works.
Eliminate alternatives
Use stated limits and exclusions to identify what remains possible.
02
Three types of deductive reasoning
Four questions each on conditional rules, ordering and elimination.
Conditional rules
Apply implications, necessary conditions and chains of rules.
Ordering
Combine precedence rules and fixed slots without adding unstated restrictions.
Elimination
Use exactly-one, exactly-two and at-least-one conditions to eliminate alternatives.
How your score is calculated
Each correct answer earns one point: 12 overall and four per topic. The percentage is accuracy on these questions. There is no countdown or speed bonus.
- 1Read the problem rules and the question.
- 2Select the one answer that must follow; you can revise it before finishing.
- 3Review your total, three topic scores and explanations for all 12 questions.
Read every condition carefully
- Treat the stated rules as true for that problem, even if real-life exceptions come to mind.
- If A implies B, B alone does not establish A.
- An arrangement that is possible is not necessarily the only possible arrangement.
FAQ
Deductive reasoning test FAQ
Deduction asks what necessarily follows when the stated premises are taken as true. These original BrainApps questions provide all the rules you need: apply a condition, combine a chain of rules, arrange a sequence or eliminate impossible alternatives. Use only the information in each problem, not assumptions about how workplaces usually operate. Your result counts correct answers in this set and shows a saved explanation for each question.
What is deductive reasoning?+
It is reasoning from premises to a conclusion that must be true if those premises are true. This test uses short, self-contained rules rather than specialist knowledge.
What kinds of questions are included?+
Twelve original problems: four on conditional rules, four on ordering and four on eliminating alternatives. Each has three options and one correct answer.
How is the result calculated?+
You receive one point per correct answer, a total out of 12 and three topic scores out of four. Every question has an explanation, including ones you answered correctly.
Is the test timed?+
No. Ten minutes is an estimated duration, not a time limit. There is no score bonus for speed.
Can these questions be used for workplace training?+
Yes: discuss which rule supports an answer and why a tempting alternative does not follow. The score describes this practice set, not a complete hiring assessment.
Should I use knowledge from outside the problem?+
No. All required conditions are stated. Do not assume additional rules, such as a typical workflow or an unstated limit on the number of active channels.
