The description is as follows:

 

Hence, ‘COW’ is the odd one out.

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.

Thus, the code for REMAIN is 8@7$%6.
Hence, option D is correct.

As Tree is found in Forest similarly Grass is found in Lawn.

Given Statement: P < Q < R < S = T

Conclusion:

I. Q < T → True (As, Q < R < S = T → Thus, it is clear that Q < T. So, the conclusion is true)

II. P > S → False (As, P < Q < R < S → Thus, it is clear that P < S. So, the conclusion is false)

III. R = T → False (As, R < S = T → Thus, it is clear that R < T. So, the conclusion is false)

Hence, the correct answer is "Only conclusion I follows".

The Venn diagram that best represents the relationship between Mammals, Whale, and Elephant is shown below:

Whale and Elephant belong to the class Mammal.

Elephants are the largest land mammals on earth and have distinctly massive bodies, large ears, and long trunks.

Hence, ‘Option 1’ is the correct answer.

1st term = 12
2nd term = 12 + 20 = 32
3rd term = 32 + 40 = 72
4th term = 72 + 80 = 152

Thus, the missing term is 5th term = 152 + 160 = 312

From Statement I:  From this statement, we have three possible scenarios as shown:

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

From Statement II:

From this statement, we get the following table

Clearly, Statement II alone is not sufficient to answer the question.

Now combining both the statements, we get,

Hence, option D is the correct answer.

From Statement 1:

C = X ≤ D ≥ R

From the statement, the conclusion H < D is not followed because H is absent.

From Statement 2:

R > Z = O > H

From the statement, the conclusion H < D is not followed because D is absent.

From Statement1 and Statement2:

We have, C = X ≤ D ≥ R > Z = O > H

From the statement, H < O = Z < R ≤ D, the conclusion H < D is followed.

Hence option D is correct.

From the common explanation, we get Bobby sits immediate right of Kirti.

Hence, Option A is correct.

Final Arrangement:

Common Explanation:

References:

Eight students Kirti, Ayushi, Manu, Sona, Aarti, Bobby, Ankita and Divya are sitting around the square table.

Four students sit on each side while rest on each corner.

Students at the side face away from the centre and students at the corner faces towards the centre.

Inferences:

So, we need to arrange as follows to accommodate the information as stated in the question,

References:

Divya sits third to the left of Ayushi.

Kirti sits opposite to Manu and both faces away from the centre.

Inferences:

From the above references, we get the following two different cases:

Case 1:

Case 2:

References:

Neither Kirti nor Manu are beside Ayushi.

Sona sits immediate left of Ankita, who sits on the side of the table.

Bobby is not an immediate right of Ayushi.

Bobby is not adjacent to Manu.

Inferences:

So, from this case 2 will be eliminated as neither Kirti nor Manu are beside Ayushi.

Now, from case 1 we get the following final arrangements:

Hence, the above image is the correct answer.

There are five such 5's as shown below

3 5 9 5 4 5 5 3 5 8 4 5 6 7 3 5 7 5 5 4 5 2 3 5 1 0

In the given figure, we can identify multiple triangles. By counting the individual triangles, we can determine that there are a total of 12 triangles in the figure.

Cup is used to drink something with the help of lips. Similarly birds collects grass with the help of beak to make her nest.

As all terms given in the question are medical terms and Hematology is also medical term.

1) Medha is sitting diagonally opposite Radha.

We can randomly place Medha on any seat and then we can place Radha opposite her.

2) Medha is on Seema’s left.

3) Raman is next to Seema and opposite Govind.

Raman must be to Seema's right as Medha is to her left.

4) Govind is on Chandra’s right.

Implies, Chandra is sitting between Govind and Radha.

5) Shanti is not on Medha’s right but is opposite to Shashi.

Implies, Shanti is to the immediate left of Medha, and Sashi is between Radha and Raman.

Hence, "Seema" is opposite Chandra.

The figure shown the no. of triangle is in the diagram so that total no. of triangle is 8 + 8 + 8 + 4 = 28

The following are the main components of the Computer:

1. Computer Hardware:

• Central processing unit: The CPU is considered as the brain of the computer. It is made up of Control Unit and Arithmetic and Logic Unit (ALU). It processes instructions and performs operations as per the requirements of the user of the computer.
• Memory: It could be primary or secondary. The primary memory is RAM which is the systems main memory that is used to temporarily store data when a program is running. The secondary memory is used for large and permanent data storage. E.g. a thumb drive.
• Computer Peripherals: It includes input and output devices. An input device is used to send information to the computer for processing. E.g. the keyboard, mouse, etc. An output device is used to display the results of processing. E.g. the printer, Modem, Projector, etc.

2. Computer Software:

• The Operating System: It is an interface between the computer and the user. It is responsible for the allocation of memory, recognising input and transmitting output. It is considered as the backbone of the computer that manages both software and hardware.
• Application Software: It is used by the user to complete specific tasks. E.g. Microsoft Word, Adobe Photoshop, etc.

TCP stands for Transmission Control Protocol.

Key Points

• The Transmission Control Protocol (TCP) is a transport protocol built on top of IP that ensures packet delivery reliability.
• In Transmission Control Protocol communication, the two computers begin by establishing a connection via an automated process called a ‘handshake.’
  • Once this handshake is complete, the first computer will begin delivering data packets to the second.
• TCP addresses many of the issues that arise with packet-based messaging, such as missing packets, out-of-order packets, duplicate transmissions, and malformed packets.
• TCP communications specify the order in which data packets should be received and verify that they arrive in the correct sequence.
• TCP specifies that if a packet does not arrive (due to congestion in intermediary networks) it be resent.

Additional Information

• A server is a computer or system that across a network distributes resources, data, services, or programmes to other computers known as clients.
• A socket is one of the two ends of a two-way communication link between two networked programmes.
• The norms and customs of a group or a regular procedure are referred to as a protocol.

The correct answer is option 4, i.e., They help you to club a group of commands and run them one after another

Additional Information

• A batch file is a text file that contains a sequence of commands for a computer operating system. It's called a batch file because it batches (bundles or packages) into a single file a set of commands that would otherwise have to be presented to the system interactively from a keyboard one at a time.
• Its extention is .bat.

The correct answer is OMR.

Important Points

• Optical mark recognition
  • It is the input device used to scan a marked answer book of a multiple choice question paper.
  • An optical answer sheet or bubble sheet is a special type of form used in multiple-choice question examinations. 
  • Optical mark recognition is used to detect answers.

Additional Information

• OCR
  • ​OCR (Optical Character Recognition) recognizes all the characters from the paper document.
  • It collects and stores them into an editable document.
• ​MICR
  • ​The term magnetic ink character recognition (MICR) refers to the line of numbers that appears at the bottom of a check.
  • The MICR line is a group of three numbers, which are the check number, account number, and bank routing number.
• Card reader
  • A card reader is a data input device that reads data from a card-shaped storage medium.

The correct answer is .

A dot matrix printer is a type of printer that uses a matrix of small pins to create characters or images on paper. Let's analyze each statement to determine the correct answer:
i) Prints an entire line at a time: This statement is incorrect. A dot matrix printer prints one character at a time by striking an ink-soaked ribbon against the paper. It does not print an entire line at a time.
ii) Is a non-impact printer: This statement is incorrect. A dot matrix printer is an impact printer because it uses physical force to create the characters. The pins strike the ribbon, which transfers ink to the paper, resulting in the printed output.
iii) Allows multiple copies to be taken at a time: This statement is correct. Dot matrix printers have the ability to create multiple copies simultaneously. This is achieved by using carbon paper or carbonless paper, which allows the impact of the pins to transfer the image to multiple layers of paper.
iv) Prints one character at a time: This statement is correct. Dot matrix printers operate by individually striking pins against an ink-soaked ribbon to create characters. Each pin represents one dot, and the combination of dots forms the characters or images on the paper.
Based on the analysis above, the correct answer is C: iii and iv. A dot matrix printer allows multiple copies to be taken at a time and prints one character at a time.
