TCS Placement Papers 2024 - Actual Questions & Solutions

This section contains real questions from TCS NQT 2024 based on candidate experiences from GeeksforGeeks, PrepInsta, and interview forums.

Numerical Ability Questions (2024)

Question 1: Percentage and Profit & Loss

Q1: A shopkeeper marks his goods 20% above cost price but allows a discount of 10%. What is his profit percentage?

Solution:

Let CP = ₹100 Marked Price (MP) = 100 + 20% of 100 = ₹120 Discount = 10% of 120 = ₹12 Selling Price (SP) = 120 - 12 = ₹108 Profit = 108 - 100 = ₹8 Profit % = (8/100) × 100 = 8%

Answer: 8%

Question 2: Time and Work

Q2: A can complete a work in 12 days, B in 15 days, and C in 20 days. If they work together, in how many days will they complete the work?

Solution:

Let total work = LCM of 12, 15, 20 = 60 units

A’s efficiency = 60/12 = 5 units/day B’s efficiency = 60/15 = 4 units/day C’s efficiency = 60/20 = 3 units/day

Combined efficiency = 5 + 4 + 3 = 12 units/day Time taken = 60/12 = 5 days

Answer: 5 days

Question 3: Ratio and Proportion

Q3: The ratio of ages of A and B is 3:5. After 8 years, the ratio becomes 5:7. Find the present age of A.

Solution:

Let present ages be 3x and 5x.

After 8 years:

• A’s age: 3x + 8
• B’s age: 5x + 8

Given: (3x + 8)/(5x + 8) = 5/7

7(3x + 8) = 5(5x + 8) 21x + 56 = 25x + 40 4x = 16 x = 4

Present age of A = 3x = 3 × 4 = 12 years

Answer: 12 years

Verbal Ability Questions (2024)

Question 4: Reading Comprehension

Q4: Read the passage and answer: “Artificial Intelligence is transforming industries by automating processes and enabling data-driven decisions. However, concerns about job displacement and ethical implications remain significant.” What is the main concern mentioned?

Answer: Job displacement and ethical implications

Explanation: The passage explicitly mentions concerns about job displacement and ethical implications as significant issues related to AI.

Question 5: Grammar - Error Spotting

Q5: Identify the error: “Neither of the students were present in the class.”

Error: “were” should be “was”

Correct Sentence: “Neither of the students was present in the class.”

Explanation: “Neither” is singular and requires singular verb “was”.

Reasoning Ability Questions (2024)

Question 6: Syllogism

Q6: Statements: All cats are animals. Some animals are dogs. Conclusions: I. Some cats are dogs. II. All dogs are cats.

Solution:

Analyzing the statements:

• All cats are animals (A → B)
• Some animals are dogs (B → C, some)

Conclusion I: Some cats are dogs

• Cannot be concluded. Some animals are dogs, but cats are a subset of animals. We cannot say some cats are dogs. Invalid

Conclusion II: All dogs are cats

• This cannot be concluded. Invalid

Answer: Neither conclusion follows

Question 7: Coding-Decoding

Q7: If “CAT” is coded as “3120”, “DOG” is coded as “4157”, then how is “RAT” coded?

Solution:

Pattern analysis:

• C = 3, A = 1, T = 20 → “3120”
• D = 4, O = 15, G = 7 → “4157”

Pattern: Position of letter in alphabet

For “RAT”:

• R = 18
• A = 1
• T = 20

Answer: “18120”

Programming Logic Questions (2024)

Question 8: Output Prediction

Q8: What will be the output of the following C code?

#include <stdio.h>
int main() {
    int x = 5;
    printf("%d", x++ + ++x);
    return 0;
}

Solution:

x++ is post-increment: uses value 5, then increments to 6 ++x is pre-increment: increments 6 to 7, then uses value 7

Result: 5 + 7 = 12

Answer: 12

Coding Problems (2024)

Question 9: Array Manipulation

Q9: Find the second largest element in an array.

Problem Statement: Given an array of integers, find the second largest element.

Example:

Input: [12, 35, 1, 10, 34, 1]
Output: 34

Solution (Java):

public int findSecondLargest(int[] arr) {
    if (arr.length < 2) return -1;

    int largest = Integer.MIN_VALUE;
    int secondLargest = Integer.MIN_VALUE;

    for (int num : arr) {
        if (num > largest) {
            secondLargest = largest;
            largest = num;
        } else if (num > secondLargest && num != largest) {
            secondLargest = num;
        }
    }

    return secondLargest == Integer.MIN_VALUE ? -1 : secondLargest;
}

Time Complexity: O(n)
Space Complexity: O(1)

Question 10: String Processing

Q10: Reverse words in a string.

Problem Statement: Given a string, reverse the order of words.

Example:

Input: "the sky is blue"
Output: "blue is sky the"

Solution (Java):

public String reverseWords(String s) {
    String[] words = s.trim().split("\\s+");
    StringBuilder result = new StringBuilder();

    for (int i = words.length - 1; i >= 0; i--) {
        result.append(words[i]);
        if (i > 0) result.append(" ");
    }

    return result.toString();
}

Time Complexity: O(n)
Space Complexity: O(n)
