Aptitude Test
An aptitude test is a timed, multiple-choice assessment that measures your problem-solving speed and accuracy across quantitative, logical and verbal questions. Employers and campus placements use it as a first-round filter, because it predicts how quickly you reason under pressure rather than how much you have memorised.

What a aptitude test covers
Quantitative aptitude
Arithmetic, percentages, ratios, profit and loss, time and work, speed and distance, and probability.
Logical reasoning
Number and letter series, syllogisms, blood relations, coding-decoding, seating arrangements and pattern recognition.
Verbal ability
Reading comprehension, synonyms and antonyms, sentence correction and error spotting.
Data interpretation
Reading tables, bar charts, pie charts and line graphs to compute answers quickly and accurately.
5 sample aptitude test questions with answers
Genuinely-correct, worked examples. Try each one before opening the answer, then practise the full set under timed, scored conditions on OnJob.
Q1.A can finish a job in 10 days and B in 15 days. Working together, how long do they take?
Answer: A does 1/10 of the work per day and B does 1/15. Together they do 1/10 + 1/15 = 3/30 + 2/30 = 5/30 = 1/6 per day, so they finish in 6 days.
Q2.A price rises 20% and then falls 20%. What is the net change?
Answer: Start at 100. A 20% rise gives 120; a 20% fall on 120 removes 24, leaving 96. The net effect is a 4% decrease, because each percentage change applies to a different base.
Q3.Find the next term in the series: 2, 6, 12, 20, 30, ?
Answer: The differences are 4, 6, 8, 10 — increasing by 2 each time — so the next difference is 12, giving 30 + 12 = 42. Equivalently each term is n×(n+1): 1×2, 2×3, 3×4, and so on.
Q4.Divide 600 between A and B in the ratio 2:3.
Answer: The ratio has 2 + 3 = 5 parts, so each part is 600 ÷ 5 = 120. A gets 2 parts = 240 and B gets 3 parts = 360.
Q5.A bag has 3 red and 2 blue balls. What is the probability of drawing a red ball?
Answer: Probability is favourable outcomes ÷ total outcomes = 3 red ÷ 5 total = 3/5 = 0.6, assuming each ball is equally likely to be drawn.
How to prepare for a aptitude test
- 1
Master the standard formulas for each topic — percentages, ratios, time-and-work and averages cover most quantitative questions.
- 2
Practise mental arithmetic and learn shortcuts so you save the clock; aptitude tests reward speed as much as accuracy.
- 3
Always read whether negative marking applies. If it does, skip questions you cannot solve quickly rather than guess blindly.
- 4
Solve full-length, timed mock papers so you build stamina and learn to allocate time across sections.
- 5
Review every wrong answer to find the underlying concept gap, not just the right number.
