If the Chief Minister passes away without a successor, the Governor may use discretionary powers unless the ruling party nominates a replacement, leaving the Governor with no choice but to make the appointment.

Lord Ellenborough admitted in 1840 that India had to transmit large sums annually to Britain without substantial returns.

Let, the measure of the required angled be A°.
Then, measure of its complement = ( 90 – A )° measure of its supplement = (180 – A)°
According to question,
6(90° – A) = 2(180° – A) –12°
⇒ 540° – 6A = 360° – 2A – 12°
⇒ 4A = 192°
⇒ A = 48°.

All even numbers between 1 and 50 = 2 to 48

Hence, Option D is correct.

Suraj's rate of work: Suraj can complete the work in 80 days, so his rate of work is 1/80 of the work per day.

Mangal's efficiency: Mangal is 60% as efficient as Suraj. So, Mangal's rate of work will be 60% of Suraj's rate, or (0.60 × 1/80) = 1/133.33 of the work per day.

Combined rate of work: When Suraj and Mangal work together, their combined rate is: (1/80) + (1/133.33).

To add these, we convert them to have a common denominator: (1/80) = 5/400 and (1/133.33) = 3/400.

So, the combined rate is (5/400) + (3/400) = 8/400 = 1/50.

Time taken to complete the work: Since their combined rate is 1/50, they will complete the work in 50 days.

Thus, the answer is 50 days.

A can complete a piece of work in 20 days, and B can do the same work in 30 days.

To find out how many days A and B will take to finish the work together:

• Calculate the work done by A in one day: 1/20 of the work.
• Calculate the work done by B in one day: 1/30 of the work.
• Add both rates: 1/20 + 1/30 = 1/12 of the work per day.

Therefore, A and B working together can complete the work in 12 days.

Hence, Option B is correct.

7 × 57 + 7 × 65 = 854
Since the 7th number came twice, it is added two times.
So the answer = 854 – 13 × 60 = 74
Hence, Option D is correct.

The HCF and LCM of two numbers are 12 and 924.
Let the numbers be 12p and 12q where p and q are prime to each other.
∴ LCM = 12pq
∴ 12pq = 924
⇒ pq = 77
∴ Possible pairs are (1 , 77) and (7 ,11)
Hence , required answer is 2.

Using Rule 1 :
1st number × 2nd number = L.C. M. × H.C.F,
Let LCM be L and HCF be H, then L = 4H
∴ H + 4H = 125
⇒ 5H = 125

∴ L = 4 × 25 = 100

Height of an equilateral triangle

Hence, Option A is correct.

Hence, Option A is correct.

1st term = 3
2nd term = 3 + 9 = 12
3rd term = 12 + 15 = 27
4th term = 27 + 21 = 48
5th term = 48 + 27 = 75
6th term = 75 + 33 = 108

Thus, the missing term is 7th term = 103 + 39 = 147

The logic is x³ : (x+1)³ + 1
                   2³ : (2 + 1)³ + 1
                   2³ : 3³ + 1
                   8  :  28
27 = 3³
so next digit (n+1)³ + 1 = (3 + 1)³ + 1 = 64 + 1 = 65

All these are part of a vehicle.

Checking Statement I:
Using the above references, we get the following arrangement:

Clearly, A is sitting immediately left of C.
Hence data in statement I is sufficient to answer the question.
Checking Statement II:
Using the above references, we get the following arrangement:

Hence data in statement II is not sufficient to answer the question.
Hence, Option A is correct.

1st term = 5
2nd term = 5 + (4*1) = 5 + 4 = 9
3rd term = 9 + (4*2) = 9 + 8 = 17
4th term = 17 + (4*3) = 17 + 12 = 29
5th term = 29 + (4*4) = 29 + 16 = 45

Thus, the missing number is 6th term = 45 + (4*5) = 45 + 20 = 65

PCB stands for Process Control Block.
The Process Control Block (PCB) is a data structure used by operating systems to manage processes. It contains all the necessary information about a process that the operating system needs to manage and control the execution of the process.
The PCB includes the following information:
1. Process ID (PID): A unique identifier assigned to each process by the operating system.
2. Process State: Indicates the current state of the process, such as running, ready, waiting, or terminated.
3. Program Counter: Stores the address of the next instruction to be executed by the process.
4. CPU Registers: Contains the values of the CPU registers being used by the process, such as the accumulator, stack pointer, and program status word.
5. Memory Management Information: Includes information about the memory allocated to the process, such as base and limit registers, page tables, and segment tables.
6. Scheduling Information: Contains data related to process scheduling, such as priority, time slice, and waiting time.
7. I/O Status Information: Stores the status of I/O operations initiated by the process, such as the list of open files and their file descriptors.
8. Parent Process ID: Stores the PID of the parent process that created the current process.
9. Child Process ID: Stores the PID of the child process created by the current process, if any.
The PCB plays a crucial role in process management:
- Context Switching: When the operating system switches from one process to another, it saves the context of the currently running process in its PCB and restores the context of the next process from its PCB.
- Process Scheduling: The PCB contains scheduling information that helps the operating system determine the priority and order in which processes should be executed.
- Process Communication: The PCB can be used to facilitate process communication by providing information about shared resources, inter-process communication channels, and synchronization mechanisms.
- Resource Management: The PCB includes information about the resources allocated to the process, such as memory, files, and I/O devices, which helps the operating system manage and track resource usage.
In conclusion, the Process Control Block (PCB) is a data structure used by operating systems to manage and control processes. It contains essential information about a process, including its state, CPU registers, memory management details, and scheduling information. The PCB plays a crucial role in process management, including context switching, process scheduling, process communication, and resource management.

Direct Method of Deadlock Prevention

A direct method of deadlock prevention is to prevent the occurrence of circular waits. Here is a detailed explanation:

Mutual Exclusion:
- Mutual exclusion refers to the condition where a resource can only be allocated to one process at a time.
- Preventing mutual exclusion is not a direct method of deadlock prevention because it may not always be feasible to allow multiple processes to access a resource simultaneously.
Hold and Wait:
- Hold and wait refers to the condition where a process holds a resource while waiting for another resource.
- Preventing hold and wait is not a direct method of deadlock prevention because it may not always be possible for a process to acquire all the required resources at once.
Circular Waits:
- Circular waits refer to the condition where a set of processes form a circular chain, with each process in the chain waiting for a resource held by the next process in the chain.
- Preventing circular waits is a direct method of deadlock prevention as it eliminates the possibility of a deadlock occurring due to circular dependency.
No Preemption:
- No preemption refers to the condition where a resource cannot be forcibly taken away from a process.
- While preventing no preemption can help in avoiding certain deadlocks, it is not a direct method of deadlock prevention as it does not eliminate the possibility of circular waits.
Therefore, the correct answer is C: Circular waits. Preventing the occurrence of circular waits is a direct method of deadlock prevention.

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.

To find out what will happen when selecting Column G and H and choosing Insert → Columns, we need to understand the behavior of the Insert Columns function in Excel.
When selecting a range of cells and choosing to insert columns, the inserted columns will be added to the left of the selected range.
In this case, we are selecting Column G and H.
So, if we choose to insert columns, the following will happen:
- Two columns will be inserted after Column F because the selected range starts from Column G and H is the next column.
- Therefore, the correct answer is A: 2 Columns will be inserted after Column F.
Note: It's important to mention that the behavior may vary depending on the version of Excel or the settings applied. However, in most versions, this is the default behavior.

Answer:
The horizontal and vertical scroll bars in a worksheet allow users to navigate and view different rows and columns of data. Here is a detailed explanation of how the scroll bars are used:
1. Split a worksheet into two panes:
- By using the horizontal and vertical scroll bars, you can split a worksheet into two panes. This is particularly useful when you want to view different sections of a large worksheet simultaneously.
2. View different rows and columns:
- The horizontal scroll bar allows you to scroll left and right, enabling you to view different columns of data that are beyond the visible area of the worksheet.
- The vertical scroll bar allows you to scroll up and down, allowing you to view different rows of data that are not immediately visible.
3. Edit the contents of a cell:
- When you click on a cell in a worksheet, the contents of the cell appear in the formula bar. You can use the horizontal scroll bar within the formula bar to edit the contents of the cell if the text exceeds the width of the formula bar.
4. View different worksheets:
- If a workbook contains multiple worksheets, the horizontal scroll bar can be used to navigate between different sheets. You can scroll left or right to switch between worksheets.
In summary, the horizontal and vertical scroll bars in a worksheet are essential tools for navigating and viewing different rows and columns of data, splitting a worksheet into two panes, editing cell contents, and switching between worksheets.

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.
