How to Pass the TCS Aptitude Tests?

Every year, lakhs of engineering and graduation students apply to TCS, one of India’s largest IT employers. And almost every single one of them hits the same first wall: the TCS aptitude test.

If you’ve ever wondered, “How hard is the TCS aptitude test?” or “What topics should I actually focus on?”, you’re not alone. The good news is that this test is absolutely crackable with the right preparation strategy. It doesn’t test genius-level math. It tests how well you think, how fast you solve, and how smartly you manage your time.

This guide breaks down everything: the TCS NQT exam pattern, section-wise topics, sample questions with solutions, and a week-by-week preparation plan, so you walk into the test knowing exactly what to expect.

What is the TCS Aptitude Test?

The TCS aptitude test, officially part of the TCS National Qualifier Test (NQT), is the first screening round in TCS’s recruitment process for freshers and entry-level candidates. It evaluates your:

• Numerical ability: percentages, ratios, time & work, speed-distance
• Logical reasoning: patterns, arrangements, syllogisms, puzzles
• Verbal aptitude: reading comprehension, grammar, sentence correction
• Problem-solving under time pressure: not just knowledge, but speed

The test is conducted online and is divided into two levels, TCS Foundation and TCS Advanced, based on the role you’re applying for.

Structure of TCS Aptitude Test

TCS, a global IT services and consulting firm, uses aptitude tests to assess candidates’ analytical, logical, and problem-solving abilities. These tests evaluate candidates’ suitability for various roles within the organization. The goal of the TCS assessment test is to evaluate a candidate’s aptitude for numerical ability and logical reasoning skills. There are multiple-choice questions in it, and you have a specific period of time to answer all of them. The exam is divided into several portions, each of which focuses on a distinct ability.

The format of the TCS Aptitude Questions and Answers has recently been modified, and the test has been broken down into two main sections: the TCS Foundation and the TCS Advanced Test. The TCS Foundation Test is quite challenging, whereas the TCS Advanced Aptitude is extremely difficult.

TCS NQT Exam Pattern 2026

Understanding the structure is your first step. Here’s the complete breakdown:

TCS Foundation Test

Section	Topics Covered	No. of Questions	Time
Numerical Ability	Percentages, Ratios, Profit & Loss, Time-Speed-Distance, Number Systems	20	40 mins
Logical Reasoning	Series, Arrangements, Blood Relations, Coding-Decoding, Syllogisms	20	30 mins
Verbal Ability	Reading Comprehension, Grammar, Vocabulary, Sentence Correction	20	30 mins

TCS Advanced Test

Section	Topics Covered	No. of Questions	Time
Advanced Quantitative	Algebra, Permutations & Combinations, Probability, Data Interpretation	20	35 mins
Advanced Reasoning	Critical Thinking, Complex Puzzles, Decision Making	20	30 mins
Coding (if applicable)	Basic programming logic, pseudo-code	1–2	20 mins

The foundation test is challenging; the advanced test is significantly harder. Most fresher roles require clearing only the foundation level. TCS Digital and Ninja roles may require advanced scores.

Section-Wise Topics and Weightage for TCS NQT

Now, let’s focus on the section-wise topics and their weightage:

1. Numerical Ability — High Priority

This is where most students lose marks — not because the concepts are hard, but because they are slow. Focus on:

Topic	Importance	Quick Tip
Percentages	Very High	Learn % shortcuts — avoid full division
Time, Speed & Distance	Very High	Memorize relative speed formulas
Time & Work	High	Use the LCM method for faster solving
Profit & Loss	High	Remember: SP = CP × (1 ± profit/loss%)
Number Systems	Medium	Divisibility rules save 30–40 seconds per question
Ratio & Proportion	Medium	Practice allegation method
Averages & Mixtures	Medium	Extremely predictable — easy scoring area
Simple & Compound Interest	Low-Medium	Formula-based — just practice 5–6 variants

2. Logical Reasoning — Medium-High Priority

Topic	Importance
Number & Letter Series	Very High
Coding-Decoding	Very High
Blood Relations	High
Seating Arrangements	High
Syllogisms	Medium
Direction Sense	Medium
Odd One Out	Low

3. Verbal Ability — Do Not Ignore

Many students neglect this section and regret it. Each question here takes the least time but carries equal marks.

Topic	Importance
Reading Comprehension	Very High
Fill in the Blanks (Grammar)	High
Sentence Correction	High
Para Jumbles	Medium
Vocabulary (Synonyms/Antonyms)	Medium

TCS Aptitude Questions PDF – Solved

Check out these solved previous year’s question papers of TCS aptitude questions.

Question 1: In a class, the average height of boys is 165 cm, and the average height of girls is 155 cm. If the average height of the whole class is 160 cm, what is the ratio of boys to girls in the class?

Let the number of boys be B and the number of girls be G. The total height = B * 165 + G * 155. Given total height = (B + G) * 160. Solve for B/G, the ratio is 3:2.

Question 2: If x + y = 10 and 3x – 2y = 4, find the value of x.

Solve the second equation for x: x = (4 + 2y) / 3. Substitute x in the first equation: (4 + 2y) / 3 + y = 10. Solving for y, we get y = 3. Substituting y in x, we get x = 4.

Question 3: The difference between a number and its two-fifths is 400. Find the number.

Let the number be N. We have N – 2/5 * N = 400. Solving for N, we get N = 1000.

Question 4: A train travels a distance of 360 km in 5 hours. What is its speed?

Speed = Distance / Time. Speed = 360 km / 5 hours = 72 km/h.

Question 5: If 20% of a number is 50, what is 40% of the same number?

Let the number be N. We have 0.20N = 50. Solving for N, we get N = 250. Therefore, 40% of N is 0.40 * 250 = 100.

Question 6: A shopkeeper sold an article for $450, incurring a loss of 10%. What was the cost price of the article?

Let the cost price be C. Selling price = Cost price – Loss. We have 450 = C – 0.10C. Solving for C, we get C = 500.

Question 7: Simplify: √(64 – 9) + √(25 + 16).

√(64 – 9) + √(25 + 16) = √55 + √41.

Question 8: If 2x – 3 = 7, what is the value of x?

Add 3 to both sides: 2x = 10. Divide by 2: x = 5.

Question 9: If the base of a rectangle is 12 cm and its height is 8 cm, what is its area?

Area of rectangle = length × width = 12 cm × 8 cm = 96 cm².

Question 10: Find the value of 2^3 * 3^2.

2^3 * 3^2 = 8 * 9 = 72.

TCS NQT Aptitude Test with Descriptive Answers

TCS aptitude tests are a series of questions that are used to assess the skills and abilities of candidates applying for jobs at TCS. Check them out here.

Question 11: A car travels a distance of 540 km in 6 hours. What is its speed in m/s?

Answer: Speed = Distance / Time. Speed = 540 km / 6 hours = 90 km/h. Convert to m/s: 90 km/h × (1000 m / 1 km) × (1 h / 3600 s) = 25 m/s.

Question 12: If 25% of a number is 75, what is 50% of the same number?

Answer: Let the number be N. We have 0.25N = 75. Solving for N, we get N = 300. Therefore, 50% of N is 0.50 * 300 = 150.

Question 13: If a shirt is sold for $30 with a 15% profit, what was its cost price?

Answer: Let the cost price be C. Selling price = Cost price + Profit. We have 30 = C + 0.15C. Solving for C, we get C = 26.09.

Question 14: Solve: 5x + 8 = 23.

Answer: Subtract 8 from both sides: 5x = 15. Divide by 5: x = 3.

Question 15: The area of a square is 121 square units. What is the length of its side?

Answer: Side length of square = √Area = √121 = 11 units.

Question 16: If 60% of a number is 120, what is 80% of the same number?

Answer: Let the number be N. We have 0.60N = 120. Solving for N, we get N = 200. Therefore, 80% of N is 0.80 * 200 = 160.

Question 17: A circle has a diameter of 14 cm. What is its circumference?

Answer: Circumference = π * diameter = π * 14 cm = 43.96 cm.

Question 18: Simplify: (2/5) * (5/8).

Answer: (2/5) * (5/8) = 1/4.

Question 19: If x – 3y = 7 and 4x + y = 19, find the value of x.

Answer: Solve the first equation for x: x = 3y + 7. Substitute x in the second equation: 4(3y + 7) + y = 19. Solving for y, we get y = 1. Substituting y in x, we get x = 10.

Question 20: If the difference between a number and its three-seventh is 200, find the number.

Answer: Let the number be N. We have N – 3/7 * N = 200. Solving for N, we get N = 350.
