Question: If the ratio of boys to girls in a class is 3:5, and the total number of students is 160, how many boys are there?

Answer: (3 / (3 + 5)) * 160 = 60 boys

Question: A train travels from City A to City B at a speed of 80 km/h and returns from City B to City A at a speed of 60 km/h. What is the average speed for the entire round trip?

Answer: (2 * 80 km/h * 60 km/h) / (80 km/h + 60 km/h) = 96 km/h

Question: If the area of a square is 36 square meters, what is its perimeter?

Answer: Side length of square = √(Area) = √36 = 6 meters

Perimeter = 4 * 6 = 24 meters

Question: If x = 5 and y = 7, what is the value of 3x + 2y?

Answer: 3(5) + 2(7) = 15 + 14 = 29

Question: A car travels a distance of 180 km with an average speed of 60 km/h. How long did the journey take in hours?

Question: Find the missing number in the sequence: 2, 6, 12, ?, 30, 42

Answer: The pattern is increasing by multiples of 2 each time.

Missing number: 2 * 4 = 8

Question: If the selling price of an item is $500, and the profit earned is 25%, what is the cost price?

Answer: Cost Price = Selling Price / (1 + Profit Percentage)

Cost Price = $500 / (1 + 0.25) = $500 / 1.25 = $400

Question: Solve the equation: 4x – 6 = 10

Answer: 4x = 10 + 6 = 16

x = 16 / 4 = 4

Question: If the area of a rectangle is 45 square units and its length is 9 units, what is its width?

Answer: Width = Area / Length = 45 square units / 9 units = 5 units

Question: A shopkeeper offers a discount of 20% on an item. If the discounted price is $320, what was the original price?

Answer: 3x = 22 – 7 = 15

x = 15 / 3 = 5

Question: What is the next number in the series: 2, 4, 8, 16, ?

Answer: The pattern is multiplying by 2 each time.

Next number: 16 * 2 = 32

Question: If the perimeter of a square is 40 cm, what is the length of one side?

Answer: Perimeter = 4 * Side length

Side length = Perimeter / 4 = 40 cm / 4 = 10 cm

Question: What is 30% of 200?

Answer: 30% of 200 = (30 / 100) * 200 = 0.30 * 200 = 60

Question: Solve the equation: 2y + 3 = 11

Now, let’s talk about some common TCS interview questions for freshers. We will cover technical questions as well as HR questions. These questions cover a wide range of topics and can help you prepare for your interview.

Technical Questions

Here are 10 technical interview questions that freshers might encounter in a TCS interview:

Question: Explain the concept of Object-Oriented Programming (OOP) and its key principles.

Answer: Object-Oriented Programming is a programming paradigm that uses objects to represent real-world entities. The key principles of OOP are encapsulation, inheritance, and polymorphism.

Question: What is the difference between a class and an object in OOP?

Answer: A class is a blueprint or template that defines the structure and behavior of objects, whereas an object is an instance of a class, representing a specific entity with its own data and behavior.

Question: How does dynamic memory allocation work in C/C++? What are the functions used for dynamic memory allocation?

Answer: Dynamic memory allocation in C/C++ is done using ‘malloc()’ and ‘free()’ functions. In C++, ‘new’ and ‘delete’ operators can also be used for dynamic memory allocation and deallocation.

Question: What are the differences between the ‘printf()’ and ‘scanf()’ functions in C?

Answer: ‘printf()’ is used for output, displaying data on the screen, while ‘scanf()’ is used for input, reading data from the user or a file.

Question: Explain the concept of data structures and give an example of a real-world application for each of the following: arrays, linked lists, and stacks.

Answer: Data structures are ways of organizing and storing data to perform operations efficiently. For example, arrays are used to store and access a collection of elements, linked lists are used for dynamic data storage, and stacks are used for managing function calls in programming.

Question: What are pointers in C/C++? How are they different from variables?

Answer: Pointers are variables that store memory addresses. Unlike regular variables that store values, pointers store addresses of other variables or memory locations.

Question: What is the difference between overloading and overriding in object-oriented programming?

Answer: Overloading refers to having multiple functions with the same name but different parameters within the same class, while overriding is when a subclass provides a specific implementation for a method that is already defined in its superclass.

Question: What are SQL injection attacks, and how can they be prevented?

Answer: SQL injection attacks are a type of cybersecurity vulnerability where malicious SQL queries are inserted into input fields. To prevent them, use parameterized queries, input validation, and avoid concatenating user input directly into SQL queries.

Question: Explain the concept of recursion and provide an example of a recursive function.

Answer: Recursion is a programming technique where a function calls itself to solve a problem. An example of a recursive function is the factorial function, where factorial(n) = n * factorial(n-1) for n > 0 and factorial(0) = 1.

Question: What is the difference between HTTP and HTTPS?

Answer: HTTP (Hypertext Transfer Protocol) is a standard protocol used for transmitting data over the internet, but it is not secure. HTTPS (Hypertext Transfer Protocol Secure) is the secure version of HTTP, where data is encrypted during transmission, ensuring a more secure communication channel.
