A ratio equivalent to 3 : 7 is:
To find a ratio equivalent to 3 : 7, we need to find a pair of numbers that have the same ratio when simplified. Let's try the options:

(i) 3 : 9 → This simplifies to 1 : 3, not the same as 3 : 7
(ii) 6 : 10 → This simplifies to 3 : 5, not the same as 3 : 7
(iii) 9 : 21 → This simplifies to 3 : 7, which is the same as 3 : 7, so the answer is (iii).

Diagonal of a room = √(l² + b² + h²)
So the answer = √(20² + 10² + 20²) = √900 = 30 meters
Hence, Option B is correct.

πr² + 2πr = 704
πr(r + 2) = 704

r × (r + 2) = 224
r = 14
So the answer

Hence, Option C is correct.

Hence, Option B is correct.

= 9 km

From Statement 1:
H sits to the immediate right of D.
Two persons sit between D and F.
A is an immediate neighbour of M, who sits to the immediate right of F.

So, H sits to the immediate left of N.
The data in Statement I alone is sufficient to answer the question.
From Statement 2:
F and N are immediate neighbours and M sits immediate right of F.
A sits third to the left of N.
Here, we can not determine who sits immediate left of N.

Hence, option A is the correct answer.

An audio output unit
An audio output unit refers to a device that produces sound or audio output. Here are some key points to understand about audio output units:
1. Can speak out small range of digits and specified words:
- Audio output units are capable of producing sound in the form of spoken words and digits.
- They can be programmed to speak out specific words or digits, such as phone numbers, addresses, or other predetermined information.
2. Is not used in information system:
- This statement is incorrect. Audio output units are commonly used in information systems to provide auditory feedback or instructions to users.
- For example, automated phone systems often use audio output units to provide instructions or read out options to callers.
3. Is very expensive and is thus not used:
- This statement is also incorrect. Audio output units come in a wide range of prices, depending on their complexity and capabilities.
- While some high-end audio output units may be expensive, there are also many affordable options available in the market.
4. Is normally used to give only background music:
- This statement is incorrect. While audio output units can be used to play background music, their functionality extends far beyond that.
- They are commonly used in various applications such as multimedia systems, gaming consoles, public announcement systems, and more.
In conclusion, an audio output unit is a versatile device used for producing sound or audio output. It can speak out a small range of digits and specified words, is commonly used in information systems, comes in a wide range of prices, and can be used for various purposes beyond playing background music.

Control footings are printed because:
- It summarizes information in logically grouped items: Control footings are added to documents to provide a summary or overview of the information contained within the document. They help to organize and group related information together, making it easier for the reader to understand and navigate the document.
- It is required in documentation: In many industries, control footings are a standard requirement in documentation. They are often mandated by regulatory bodies or industry standards to ensure that important information is clearly presented and easily accessible.
- It is necessary for error detection: Control footings can help to identify errors or inconsistencies in the document. By summarizing key information and cross-referencing it with other parts of the document, control footings can help to catch any discrepancies or mistakes that may have been overlooked.
- It is suggested by management: Management may suggest the use of control footings as a best practice for document organization and clarity. Control footings can help to improve the readability and usability of documents, making them more effective tools for communication.
Overall, control footings are printed because they provide a concise summary of information, meet documentation requirements, aid in error detection, and are recommended by management.

Telnet is a Remote Login Protocol
Telnet is a protocol that allows users to remotely log in to another computer or server over a network. It provides a virtual terminal connection, allowing users to access and interact with the remote system as if they were physically present. Here are some key points to understand about Telnet:
1. Definition:
- Telnet is a network protocol used to establish a remote login session between a local client and a remote server.
- It allows users to access and control the functions of a remote computer or server over a network.
2. Functionality:
- Telnet enables users to log in to a remote system and perform various tasks and operations.
- It provides a command-line interface to interact with the remote system's operating system and execute commands.
3. Client-Server Model:
- Telnet follows a client-server model, where the local client initiates a connection request to the remote server.
- The server listens for incoming Telnet connections on a specific port (default port 23) and responds to client requests.
4. Terminal Emulation:
- Telnet provides terminal emulation, allowing the local client to access the remote system's command-line interface.
- It emulates a terminal or console on the local machine, providing a text-based interface to interact with the remote server.
5. Security Concerns:
- Telnet transmits data, including login credentials, in plain text format, making it vulnerable to eavesdropping and data interception.
- Due to its lack of encryption, Telnet is considered insecure, and its usage is discouraged in favor of more secure protocols like SSH (Secure Shell).
In conclusion, Telnet is a remote login protocol that allows users to establish a virtual terminal connection with a remote computer or server over a network. It provides a command-line interface for executing commands and accessing the remote system's functions. However, its lack of encryption makes it insecure for transmitting sensitive information, and alternative protocols like SSH are recommended for secure remote access.

Representation of Digital Signals:

• Binary Codes: Digital signals can be represented using binary codes, which are sequences of 0s and 1s.


• 0 and 1: Another common representation of digital signals is using the binary digits 0 and 1.


• High and Low: Digital signals can also be represented using the concepts of "high" and "low" voltage levels. A high voltage level represents a logical 1, while a low voltage level represents a logical 0.


• All of the Above: The correct answer is option D, as digital signals can be represented using binary codes, 0 and 1, as well as high and low voltage levels.

By utilizing these various representations, digital signals can be transmitted, stored, and processed in digital systems. The choice of representation depends on the specific application and the requirements of the system.
