2. Subtle.

4. Sucres.

3. Sudoku.

1. Sugary.

5. Sullen.

Hence, the correct answer is "2, 4, 3, 1, 5".

Hence, the applicant meets all the criteria.

1st term = 1
2nd term = 1 + (1) = 2
3rd term = 2 + (1) = 3
4th term = 3 + (3) = 6
5th term = 6 + (3) = 9
6th term = 9 + (9) = 18
7th term = 18 + (9) = 27
8th term = 27 + (27) = 54

Thus, the missing term is 7th term = 27

Checking Statement I:

As per hints, following arrangements can be formed

A > E > B > C/D > D/C

Here in the above statements, clearly A is the heaviest person.

Hence data in statement I alone is sufficient to answer the question.

Checking Statement II:

As per hints, following arrangements can be formed

A > E > B/C > C/B

Since, there is no information about D, so statement II alone is not sufficient.

Hence data in statement II is not sufficient to answer the question.

Hence, Option A is correct.

P is male member and married to Q.
P is husband and Q is wife.
R is brother of P.
S is the son of R.
T, who is the sister of S will be daughter of R.
Q is the daughter-in-law of U, whose husband has died means U is the mother of P.

The pattern followed is:

Hence, the correct answer is "HS".

Lion eats deer, cat eats mouse, hawk eats pigeon but pig does not eat piglet.

Five persons A,B,C,D and E are sitting one above the other on a ladder (not necessarily in the same order).

1) B is sitting above A with one person between them.

2) Only two persons are sitting between A and C. If C is not sitting top, the figure are given below -

In which there is two case in which first one is -

Second case are given below -

After observation of both cases, B is the sitting in the middle.

Hence, "B" 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

Given

Ratio of principal and amount is 4 : 5 at a certain time. If it becomes 5 : 7 after 3 years

Concept used

Rate = (interest × 100)/(Principal × time)

Calculation

Principal : Amount = 4 : 5

Principal be equal 

Multiply the first ratio with 25 and second with 20

⇒ (4 : 5) × 25 

⇒ (5 : 7) × 20

Principal : Amount = 100 : 125

Principal : Amount = 100 : 140

Difference in amount = 140 - 125

Difference in Amount = 15

3 year = 15

1 year = 5

Rate = (interest × 100) / Principal × time

Rate = 

Rate = 5%

∴ The required simple rate of interest is 5%.

Let X and Y be two buses. Bus X travels the PA, AB, BC, CD.
Now, AD = BC = 25 km.
So, PD = PA +AD = 50km.
Bus Y travels 35km upto E.
Distance between two buses = PQ – (PD + QE)
= [150 – (50 + 35)] = 65 km.

From the final arrangement, we get “C sits at one of the extreme ends".
Hence, Option D is correct.
References:
O sits 3^rd to the right of N.
One who sits just behind O is to the immediate right of E.
Inferences:
From the above reference, we get the following cases:

References:
B is neither at any of the extreme ends nor sits exactly behind O.
The number of people sitting between C and E, is the same as the number of people sitting between E and B.
Inferences:
From the above reference, we get the following cases:

References:
D doesn’t sit at any of the extreme ends.
P sits on a seat which is exactly ahead of A.
M is not exactly ahead of E.
Inferences:
From the above reference, we get the following cases:
Case 1: Position of D cannot be fixed, thus this case is eliminated.

Case 2: We get the final arrangement as below:

Peel : Peal

The above words represent pair of homophones.

(c) is a pair of homophones. (a), (b) and (d) do not have pairs of homophones.

Hence, correct option is C.

'POLITICS' is a meaningful English word.

Hence, '1, 4, 8, 3, 2, 5, 7, 6' is the correct answer.

From the common explanation, we get O sits exactly opposite to Q.

Hence, Option B is correct.

Final Arrangement:

Common Explanation:

References:

M is sitting fourth to the right of N.

P is sitting second to the left of N.

Inferences:

From the above reference, we get the following arrangements:

References:

Q is sitting third to the right of S.

Inferences:

From the above reference, we get two different cases:

Case 1:

Case 2:

References:

S is not sitting beside P.

T is sitting second to the left of O.

O is not sitting beside M.

Inferences:

So, from this case 1 will be eliminated as S is not sitting beside P.

Thus, the final arrangement,

The correct answer is = (equal sign).

Answer:
The value displayed if the formula "= "$55.00" 5" is entered into a cell is 60 (Option B).
Here is the detailed solution:
1. The formula "= "$55.00" 5" combines a text string "$55.00" with the number 5.
2. When a text string is combined with a number using the plus sign (+) operator, Excel tries to convert the text into a number.
3. In this case, "$55.00" cannot be converted into a number because it contains a dollar sign and double quotes.
4. As a result, Excel treats "$55.00" as text and concatenates it with the number 5.
5. The result of the formula is the text string "$55.00" followed by the number 5, which is " $55.00 5".
6. Since the resulting value is a text string, it cannot be mathematically calculated.
7. Therefore, the value displayed in the cell will be the text string itself, which is "$55.00 5" (Option C).
8. Option B, which states 60, is incorrect because the formula does not perform any mathematical operations on the text string and number.
9. The correct answer is Option C, which displays the text string "$55.00 5".

Quickest way to select the entire worksheet:

• Step 1: Open the worksheet you want to select.


• Step 2: Locate the rectangle box on the upper left corner where column headings and row headings meet.


• Step 3: Click on the rectangle box.

Explanation:

The quickest way to select the entire worksheet is to click on the rectangle box on the upper left corner where column headings and row headings meet. This box is known as the "Select All" box and it allows you to select the entire worksheet in just one click.

This method is faster than other options because it saves you the time and effort of manually selecting each column or row. By clicking on the "Select All" box, you instantly select the entire worksheet including all columns, rows, and cells.

Using this method, you can quickly perform tasks such as formatting, copying, or deleting the entire worksheet without having to individually select each element. It is a time-saving technique that is particularly useful when working with large worksheets.

Therefore, the correct answer is Option D: Click on the rectangle box on the upper left corner where column headings and row headings meet.

The typical elements of process image are:

• User data


• System data


• User program


• System stack

Explanation:

• User data: This includes the data that is specific to the user and is used by the user program.


• System data: This includes the data that is used by the operating system to manage the process, such as process control block (PCB), process state, priority, etc.


• User program: This is the actual program code that is executed by the processor.


• System stack: This is the stack used by the system for managing function calls and local variables.

Therefore, the typical elements of a process image include user data, system data, user program, and system stack.

Introduction:
In this question, we are asked to identify the characteristics of a laser printer. We need to choose the correct options from the given choices.
Characteristics of a laser printer:
A laser printer is a type of printer that uses laser technology to produce high-quality prints. Let's analyze each statement given in the question and determine its accuracy:
1. Prints an entire line at a time:
- This statement is true. Laser printers use a process called "electrophotography" or "xerography" to print an entire line at a time. This process involves the use of a laser beam to create an electrostatic image of the entire line on a photosensitive drum.
- Correct
2. Non-impact printer:
- This statement is true. Laser printers are non-impact printers, which means they do not require direct contact between the print head and the paper to create an image. Instead, they use a laser beam to transfer toner onto the paper.
- Correct
3. Allows multiple copies to be taken at a time:
- This statement is false. Laser printers generally do not allow multiple copies to be taken at a time. However, some advanced laser printers may have features like duplex printing or collating, which can produce multiple copies in a single print job.
- Incorrect
4. Prints one character at a time:
- This statement is false. Laser printers do not print one character at a time. As mentioned earlier, they print an entire line at a time using a laser beam and electrostatic imaging.
- Incorrect
Conclusion:
Based on the analysis, we can conclude that the correct characteristics of a laser printer are:
- Prints an entire line at a time
- Non-impact printer
Therefore, the correct answer is (A) i and ii.

Reasons for Process Suspension:
Swapping parent process:
- When the operating system needs to free up memory resources, it may decide to swap out a parent process. This means that the process is moved from main memory to secondary storage (such as a hard disk) temporarily.
- Swapping allows the operating system to prioritize active processes and allocate resources efficiently.
Inter request:
- Process suspension can occur when a process needs to wait for an external event or resource before it can continue executing.
- For example, if a process is waiting for user input or waiting for a file to be read from the disk, it may be temporarily suspended until the requested input or data becomes available.
Timing:
- Timing can also be a reason for process suspension. This occurs when a process is scheduled to be suspended for a specific period of time, allowing other processes to execute during that time frame.
- Timing-based suspensions are often used in multitasking operating systems to ensure fair allocation of resources among different processes.
All of the above:
- The correct answer to the question is "d. All of the above" because all of the mentioned reasons (swapping parent process, inter request, and timing) can lead to process suspension.
In summary, process suspension can occur due to various reasons such as the need for memory management (swapping parent process), waiting for external events or resources (inter request), and timing-based scheduling. All of these reasons contribute to the efficient allocation of resources and fair execution of processes in an operating system.

The correct option is (1)

Herman Hollerith

 Key Points

• Herman Hollerith created the technology for punch card data processing at the end of the 1800s in order to record data on a medium that a machine could then read for the 1890 U.S. census.
• A card with data represented by holes punched at specific locations. also known as a punched card or Hollerith card.
• Punched cards were first used to "program" looms and machine for the production of textiles in the late eighteenth and early nineteenth century.

Additional Information

• Because the design of early computers was influenced by the Jacquard loom's interchangeable punch cards, it is frequently thought of as a forerunner to modern computing.
• French mathematician and philosopher Blaise Pascal made significant contributions to several branches of mathematics.

Devious: behaving in a dishonesty way
Nefarious: criminal
Surreptitious: stealthily done : secretly done
Villainous: very evil and unpleasant

• Consequences are results of something that already had happened whereas conclusions are the final verdits of discussions or ideas.
• Results: something that happens because of something else; the final situation at the end of a series of actions
• Conclusions: an opinion that you reach after thinking about something carefully
• Difficulties: the state or condition of being difficult
• Applications: the action of putting something into operation.

Hence Correct Answer is Option A
