Most Repetitive Questions in TCS NQT

1. Numerical Ability

The Numerical Ability section of TCS NQT tests a candidate’s mathematical skills. It includes topics that require strong problem-solving abilities and speed. Many questions are based on fundamental mathematical concepts and real-world applications. By practicing these repetitive questions, candidates can enhance their efficiency and accuracy.

a) Number System

The number system forms the foundation of many mathematical problems. Questions often involve finding the LCM and HCF of given numbers, determining divisibility, and converting numbers between different bases (such as decimal to binary). Candidates may also be asked to solve modular arithmetic problems. Mastering these concepts helps in tackling many numerical problems quickly.

b) Profit and Loss

Profit and loss questions test a candidate’s ability to calculate financial gains and losses in various scenarios. Common problems include determining selling price, cost price, and overall percentage gain or loss. Questions may also involve concepts like successive discounts and markups. Understanding formulas and shortcuts can help solve these efficiently.

c) Time, Speed, and Distance

This topic is crucial as it involves motion-related problems, including those on trains, boats, and vehicles. Candidates often encounter problems on relative speed, average speed, and meeting points. Real-world applications like calculating travel time based on given speed and distance frequently appear. Practicing different problem types ensures quick and accurate solutions during the exam.

d) Permutation and Combination

Permutation and combination problems deal with arrangements and selections of objects. Questions often include arranging letters of a word, selecting members for a team, and probability-based problems. Understanding factorial calculations and formulas is essential. This topic is also commonly linked to probability questions in competitive exams.

2. Logical Reasoning

Logical Reasoning is an important section in TCS NQT, designed to test a candidate’s ability to analyze and evaluate patterns and relationships. Questions in this section require critical thinking, problem-solving, and decision-making skills. By practicing commonly asked questions, candidates can develop logical reasoning techniques to improve their accuracy. Regular practice with different question types will enhance problem-solving speed.

a) Seating Arrangement

Seating arrangement problems are among the most frequently asked in logical reasoning. These involve circular, linear, and grid-based seating patterns. Candidates must determine positions based on given clues and constraints. Developing a structured approach and using diagrams can significantly improve solving time.

b) Coding-Decoding

Coding-decoding questions test a candidate’s ability to decipher patterns in letters, numbers, or symbols. These may include shifting letters in the alphabet, replacing numbers with codes, or analyzing symbol-based patterns. Understanding common coding techniques and practicing different types can help in quickly identifying the logic behind the codes.

c) Blood Relations

Blood relation questions involve determining family relationships based on given statements. These questions often include direct relationships (e.g., brother, sister, cousin) and indirect relations (e.g., father’s uncle, maternal grandmother). A clear understanding of family trees and logical deduction is essential for solving these efficiently. Practicing diagram-based approaches can simplify complex relationship problems.

d) Syllogism

Syllogism problems require logical deduction based on given premises. Candidates must evaluate statements and draw conclusions using Venn diagrams or logical reasoning. These questions often follow a structured pattern with two or three given premises leading to a conclusion. Mastering logical connectors like ‘all,’ ‘some,’ and ‘none’ is key to solving these quickly and accurately.

3. Verbal Ability

The Verbal Ability section evaluates a candidate’s command over the English language. It includes a mix of grammar, comprehension, and vocabulary-based questions. Candidates need to be well-versed in sentence construction, logical coherence, and proper usage of words. Developing reading habits and practicing common question types can significantly improve performance.

a) Sentence Completion

Sentence completion questions test knowledge of grammar, vocabulary, and contextual understanding. Candidates must fill in the blanks with appropriate prepositions, conjunctions, or verb forms. Identifying the correct tense and subject-verb agreement is crucial. Regular reading and practicing vocabulary-based questions can help in improving accuracy.

b) Reading Comprehension

Reading comprehension questions assess a candidate’s ability to analyze and interpret written content. These include finding the main idea of a passage, answering factual and inferential questions, and identifying synonyms and antonyms. Understanding different writing styles and practicing speed-reading techniques can enhance comprehension skills. Candidates should also focus on improving reading speed without losing accuracy.

c) Error Detection

Error detection questions focus on identifying grammatical errors in sentences. Common mistakes include incorrect verb forms, subject-verb agreement errors, and misuse of articles and prepositions. Candidates need a strong grasp of grammar rules to excel in this section. Regular practice with sentence correction exercises can help in quickly identifying and rectifying errors.

d) Parajumbles

Parajumble questions require arranging a set of jumbled sentences to form a coherent paragraph. Candidates need to identify logical flow, link connecting words, and maintain a proper sequence of ideas. This section tests a candidate’s ability to structure and organize information effectively. Understanding transition words and practicing different passages can improve performance.

4. Programming & Coding

The coding round in TCS NQT assesses a candidate’s problem-solving skills in programming. Questions are usually focused on fundamental programming concepts, data structures, and algorithm implementation. Practicing coding problems from different topics helps in gaining confidence and improving execution speed.

a) Pattern Printing

Pattern printing problems involve generating different patterns using loops and nested loops. Candidates may be asked to print pyramid, diamond, or Pascal’s triangle patterns. These problems test a candidate’s understanding of loop structures and logic-building skills. Mastering different patterns improves logical thinking and coding efficiency.

b) String Manipulation

String manipulation questions involve working with character sequences. Common problems include reversing a string, finding palindromes, and counting vowels and consonants. These problems help in strengthening string handling techniques. Understanding built-in string functions and practicing different variations is essential for mastering this topic.

c) Array-Based Problems

Array-based problems are frequently asked in the coding section. Candidates may be required to find the second largest element, implement sorting algorithms, or check if an array is sorted. These problems assess a candidate’s knowledge of data structures and algorithm optimization. Practicing array manipulations and sorting techniques is crucial for solving these efficiently.

d) Basic Data Structures

Basic data structures like stacks, queues, and linked lists are commonly tested. Candidates may need to implement insertion, deletion, and traversal operations. Questions on tree traversal techniques (inorder, preorder, postorder) also appear frequently. Understanding these concepts thoroughly helps in tackling complex coding problems effectively.

Final Words of Encouragement

Preparing for the TCS NQT can seem overwhelming, but with the right strategy, success is within your reach. Focus on understanding the core concepts of each section rather than rote memorization. Solve previous years’ question papers and take mock tests to improve your speed and accuracy. Stay consistent, practice regularly, and believe in yourself. With dedication and the right approach, you can ace the TCS NQT and secure your dream job. Best of luck!
