Aptitude tests are a key part of technical hiring exams, used by top tech companies to assess your problem-solving, logical reasoning, and mathematical skills. Whether you’re applying for FAANG companies or startups, aptitude questions help recruiters evaluate how quickly and efficiently you can approach complex problems. To help you get ready for exams like those on JobBinge, here’s a look at common aptitude questions and topics frequently asked in tech hiring exams.
1. Number Series and Patterns
These questions test your ability to identify patterns in numbers and predict the next term. Often, they include sequences of numbers where you need to figure out the underlying logic (arithmetic progression, geometric progression, squares, cubes, etc.).
Example Question:
What is the next number in the series?
2, 6, 12, 20, 30, ?
Solution:
The differences between consecutive numbers are 4, 6, 8, 10. So, the next difference should be 12.
30 + 12 = 42. Hence, the next number is 42.
Skills tested: Logical reasoning, pattern recognition, basic arithmetic.
2. Time, Speed, and Distance
These questions often involve the calculation of time taken, speed, or distance traveled by an object under different conditions.
Example Question:
A car travels 60 km in 1 hour and 30 minutes. What is its average speed?
Solution:
Convert 1 hour 30 minutes to hours:
1 hour 30 minutes = 1.5 hours
Average speed = Distance/Time = 60 km / 1.5 hours = 40 km/h.
Skills tested: Basic arithmetic, time management, speed calculation.
3. Profit and Loss
Profit and loss questions are designed to test your ability to calculate cost prices, selling prices, and profit percentages.
Example Question:
A shopkeeper sells an item for $400 at a profit of 20%. What is the cost price?
Solution:
Let the cost price be x.
Selling price = Cost price + Profit
400 = x + (20% of x)
400 = x + 0.2x
400 = 1.2x
x = 400 / 1.2 = $333.33
Skills tested: Percentage calculations, basic algebra.
4. Probability
Probability questions assess your understanding of likelihood and chances of events happening.
Example Question:
What is the probability of drawing an Ace from a standard deck of cards?
Solution:
There are 4 aces in a deck of 52 cards.
Probability = Favorable outcomes / Total outcomes = 4 / 52 = 1/13.
Skills tested: Probability theory, basic counting principles.
5. Work and Time
These questions test how efficiently you can calculate the amount of work done by multiple people or machines working together.
Example Question:
If 3 people can complete a task in 12 days, how long will it take for 4 people to complete the same task?
Solution:
Work done is inversely proportional to the number of people.
So, if 3 people take 12 days, the work done by 1 person will take 3 times longer.
Now, for 4 people:
Time taken = (3 * 12) / 4 = 9 days.
Skills tested: Proportions, time management, basic algebra.
6. Percentage and Ratio
These questions test your ability to work with percentages and ratios, commonly used in financial and data analysis contexts.
Example Question:
If a student scores 80% in an exam and the total marks are 500, how many marks did the student get?
Solution:
Marks obtained = 80% of 500
= (80/100) * 500 = 400 marks.
Skills tested: Percentage calculations, simple arithmetic.
7. Mixtures and Alligations
Mixture and alligation problems typically involve calculating the cost or quantity of a mixture made from different ingredients.
Example Question:
If 10 liters of milk costing $8 per liter is mixed with 15 liters of milk costing $6 per liter, what is the cost of the mixture?
Solution:
Weighted average cost of the mixture = (10 * 8 + 15 * 6) / (10 + 15)
= (80 + 90) / 25
= $6.8 per liter.
Skills tested: Weighted averages, mixtures, basic algebra.
8. Logical Reasoning and Puzzles
These questions are designed to test your analytical and critical thinking. They could involve statements, assumptions, or arrangements of people or objects.
Example Question:
If all roses are flowers and all flowers are beautiful, is it true that all roses are beautiful?
Solution:
Yes, according to the given statements, all roses are beautiful.
Skills tested: Deductive reasoning, logical thinking.
Conclusion
Aptitude questions are a staple in tech hiring exams. Whether you’re applying through JobBinge or another platform, practicing these types of questions can help you increase your speed, accuracy, and confidence. Remember, while the content is important, being able to approach problems methodically and managing your time efficiently is just as critical. By mastering these aptitude topics and regularly solving practice problems, you can ensure you’re well-prepared for any technical hiring exam that comes your way!
