Aptitude Test — free practice 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.

6 multiple-choice questions in the style of a real aptitude test, marked instantly on this page. Every answer comes with the working, so a wrong pick tells you which concept to revise. Nothing to install, no account, no email.
Q1. A train 150 m long runs at 72 km/h. How long does it take to cross a pole?
Show the worked answer
Correct answer: 7.5 seconds. 72 km/h = 72 × 5/18 = 20 m/s. Crossing a pole means covering just the train’s own length: 150 ÷ 20 = 7.5 seconds.
Q2. What is 20% of 250?
Show the worked answer
Correct answer: 50. 20% is one-fifth, and 250 ÷ 5 = 50.
Q3. The average of 5 numbers is 18. One of them, 22, is removed. What is the new average?
Show the worked answer
Correct answer: 17. The five numbers total 5 × 18 = 90. Removing 22 leaves 68 across 4 numbers, so 68 ÷ 4 = 17.
Q4. Find the simple interest on ₹8,000 at 5% per annum for 3 years.
Show the worked answer
Correct answer: ₹1,200. Simple interest is P × R × T ÷ 100 = 8,000 × 5 × 3 ÷ 100 = ₹1,200.
Q5. A shopkeeper buys an item for ₹400 and sells it for ₹500. What is the profit percentage?
Show the worked answer
Correct answer: 25%. Profit is ₹100, and profit percentage is always taken on cost price: 100 ÷ 400 = 25%.
Q6. If 3 workers build a wall in 12 days, how long do 4 workers take at the same rate?
Show the worked answer
Correct answer: 9 days. The job is 3 × 12 = 36 worker-days. Split across 4 workers that is 36 ÷ 4 = 9 days.

What an 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.
10 sample aptitude test questions with answers
Genuinely-correct, worked examples. Try each one before opening the answer, then go back to the marked practice test above and sit it against the clock.
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.
Q6. A shopkeeper offers successive discounts of 10% and then 20%. What single discount is that equivalent to?
Answer: Take the marked price as 100. A 10% discount leaves 90, and a further 20% off 90 removes 18, leaving 72. The single equivalent discount is 100 − 72 = 28%, not 30% — each discount applies to a smaller base than the one before.
Q7. Two trains 120 m and 180 m long run towards each other at 40 km/h and 50 km/h. How long do they take to cross?
Answer: In opposite directions the speeds add: 40 + 50 = 90 km/h, and 90 × 5/18 = 25 m/s. To cross, they must cover the sum of their lengths, 120 + 180 = 300 m, so the time is 300 ÷ 25 = 12 seconds.
Q8. The average age of 10 students is 15. A teacher aged 37 joins them. What is the new average?
Answer: The students total 10 × 15 = 150 years. Adding the teacher gives 150 + 37 = 187 years across 11 people, so the new average is 187 ÷ 11 = 17 years.
Q9. A sum of money doubles in 8 years under simple interest. What is the annual rate?
Answer: Doubling means the interest earned equals the principal, so SI = P. Substituting into SI = (P × R × T) ÷ 100 with T = 8 gives P = (P × R × 8) ÷ 100, so R = 100 ÷ 8 = 12.5% per year.
Q10. In how many distinct ways can the letters of the word 'LEVEL' be arranged?
Answer: LEVEL has 5 letters with L repeated twice and E repeated twice. Divide the total arrangements by the repeats: 5! ÷ (2! × 2!) = 120 ÷ 4 = 30 distinct arrangements.
How to prepare for an aptitude test
- 01
Master the standard formulas for each topic — percentages, ratios, time-and-work and averages cover most quantitative questions.
- 02
Practise mental arithmetic and learn shortcuts so you save the clock; aptitude tests reward speed as much as accuracy.
- 03
Always read whether negative marking applies. If it does, skip questions you cannot solve quickly rather than guess blindly.
- 04
Solve full-length, timed mock papers so you build stamina and learn to allocate time across sections.
- 05
Review every wrong answer to find the underlying concept gap, not just the right number.
