AP: 21, 42, 63, 84, …
a = 21
d = 42 – 21 = 21
a(n) = 210
a + (n – 1) x d = 210
21 + (n – 1) x (21) = 210
21 + 21 x n – 21 = 210
21 x n = 210
n = 10

r% of r = 49
r² = 49 × 100
r = 7 × 10 = 70
Hence, Option B is correct.

Let the measured of the required angle be P degree.
Then, its supplement = 180 – P
Now use the formula,

3P + P180°
⇒ P = 45°

Assume a distance of 60 km in each stretch. Get the average speed by the formula. Total distance/
Total time = 180/10 = 18 kmph.

Let the required number be x.
As given,

Given:

Mohit got 30% marks and failed by 25 marks

Another student scored 38% and

He got 15 more marks than passing marks

Calculation:

According to the question

⇒ 30% + 25 = 38% – 15

⇒ (38% – 30%) = (15 + 25)

⇒ 8% = 40

⇒ 1% = 5 marks

Now,

5% = 25 marks 

Then,

The necessary pass percentage required = (30% + 5%)

⇒ 35%

∴ Required pass percentage is 35%

Hence, "Printer" is the correct answer.

Important PointsInput Device: A piece of equipment/hardware that helps us enter data into a computer is called an input device. For example keyboard, mouse, etc. 

1. Keyboard:

• A simple device comprising keys and each key denotes either an alphabet, number, or number commands which can be given to a computer for various actions to be performed
• It has a modified version of typewriter keys
• The keyboard is an essential input device and computers and laptops both use keyboards to give commands to the computer

2. Joy Stick:

• It is a device that comprises a stick that is attached at an angle to the base so that it can be moved and controlled
• Mostly used to control the movement in video games
• Apart from a computer system, a joystick is also used in the cockpit of an aeroplane, wheelchairs, cranes, trucks, etc. to operate them well

3. Scanner:

• This device can scan images or text and convert it into a digital signal
• When we place any piece of a document on a scanner, it converts it into a digital signal and displays it on the computer screen

Output Device: A piece of equipment/hardware that gives out the result of the entered input, once it is processed (i.e. converts data from machine language to a human-understandable language), is called an output device. For example printers, monitors, etc. 

Printer:

• A device that makes a copy of the pictorial or textual content, usually over a paper is called a printer
• For example, an author types the entire book on his/her computer and later gets a printout of it, which is in the form of paper and is later published
• Multiple types of printers are also available in the market, which can serve different purposes

From Statement I:

From this statement, we get the following ranking.

Person in the row = 8 persons + Akansha + 4 persons + Rhea + 7 persons + Harshita + 8 persons

So, we get that Rhea is 17th from the bottom in the class.

Clearly, Statement I alone is sufficient to answer the question.

From Statement II:

From this statement, we get the following ranking.

Person in the row = 11 persons + Yamini + 13 persons + Rhea + 4 persons

So, we get that Rhea is 5th from the bottom in the class.

Clearly, Statement II alone is sufficient to answer the question.

Clearly, Either Statement I or Statement II alone is sufficient to answer the question.

Hence, option C is the correct answer.

Decoding the information, 

Given:

14 ÷ 2 + 8 × 5

After replacing the signs from left to right and using the BODMAS rule,

14 + 2 × 8 - 5

= 14 + 16 - 5

= 30 - 5

= 25

Hence, “25” is the correct answer.

Given:

Speed of train₁ = 32 km/h

Speed of train₂ = 40 km/h

Length of train₁ = 132 m

Length of train₂ = 108 m

Formula used:

If bodies moving in opposite direction = (x + y) km/h

If bodies moving in same direction = (x – y) km/h

Speed = Distance/Time

1 km/h = (5/18) m/sec

Calculation:

The sum of the length of the train = (132 + 108) m

⇒ 240m

According to the question

Relative speed = (32 + 40) km/h

⇒ 72 km/h

⇒ (72 × 5/18) m/sec = 20 m/sec

Now,

Time taken = Total distance/Speed

⇒ (240/20) sec

⇒ 12 sec

∴ Required time is 12 sec

Computers use base 2 number system to store information.

The base 2 number system, also known as the binary number system, is used by computers to store and process information. This system uses only two digits, 0 and 1, to represent all numbers and characters. Here is how computers use the base 2 number system:

Binary Digits:

• In the base 2 number system, each digit is called a binary digit or bit.


• A bit can either be 0 or 1, representing the two possible states of a switch (off or on) in a computer's electronic circuitry.


• Bits are combined to represent numbers, characters, and other types of data.

Binary Representation:

• Binary numbers are written using powers of 2, with the rightmost digit representing 2^0 (1), the next digit representing 2^1 (2), the next digit representing 2^2 (4), and so on.


• For example, the binary number 1010 represents (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (0 * 2^0) = 8 + 0 + 2 + 0 = 10.

Storage and Processing:

• Computers store all data in binary form, using a series of 0s and 1s.


• Memory cells in a computer's hardware are designed to store and retrieve binary information.


• Processors perform calculations and operations using binary logic and arithmetic.

Overall, computers use the base 2 number system because it is compatible with the electronic circuitry and logical operations of digital computers. The binary system allows computers to represent and process information in a way that is efficient and reliable.

Domain Name ".org" Represents Organization

The domain name ".org" is a top-level domain (TLD) that represents organizations. It is one of the original generic top-level domains established in 1985 along with .com, .net, .gov, and .edu. Here is a detailed explanation of why ".org" represents organizations:

• Definition: ".org" stands for organization, which is a group of people working together towards a common goal or purpose.


• Intended Use: The ".org" domain was initially intended for non-profit organizations, but it has since been expanded to include for-profit organizations as well.


• Common Usage: Many well-known organizations, such as the Red Cross, Amnesty International, and Wikipedia, use the ".org" domain for their websites.


• Identification: The ".org" domain is often associated with credibility, trustworthiness, and a dedication to a cause or mission.


• Open Registration: Unlike some other TLDs, there are no specific requirements or restrictions for registering a ".org" domain. It is open to any individual, business, or organization.


• Alternative Meanings: While the primary meaning of ".org" is organization, it can also be interpreted as organic in some contexts. However, when it comes to domain names, ".org" predominantly represents organizations.

In conclusion, the domain name ".org" represents organizations, both non-profit and for-profit, and is widely used by various reputable organizations around the world.

Answer:
802.5 is the correct answer because it provides for a collision-free protocol. Here's a detailed explanation:
802 Standards:
The 802 standards are a set of networking protocols defined by the Institute of Electrical and Electronics Engineers (IEEE). These standards define the specifications for various aspects of network communication, including data link layer protocols, physical layer specifications, and network management.
Collision:
In networking, a collision occurs when two or more devices on a network attempt to transmit data at the same time, resulting in a garbled signal. Collisions can cause data loss and network congestion, leading to decreased performance.
802.2:
- Also known as the Logical Link Control (LLC) standard.
- Defines the interface between the Media Access Control (MAC) sublayer and the network layer.
- It does not provide a collision-free protocol.
802.3:
- Also known as Ethernet.
- Defines the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol.
- CSMA/CD allows devices to detect collisions and handle them by retransmitting the data.
- It does not provide a collision-free protocol.
802.5:
- Also known as Token Ring.
- Defines a token passing protocol, where a token is passed between devices to control access to the network.
- Only the device holding the token can transmit data, ensuring a collision-free protocol.
- It provides a collision-free protocol.
802.6:
- Also known as Distributed Queue Dual Bus (DQDB).
- Defines a protocol for metropolitan area networks (MANs).
- It does not provide a collision-free protocol.
Therefore, the correct answer is 802.5 as it provides for a collision-free protocol.
