Clearly, Statement I and Statement II together are necessary to answer the question.
Hence, option E is the correct answer.

- Given Codes:
- PAINT = 74128
- EXCEL = 93596

- Analysis:
- Each letter is represented by a single digit in the code.

- Mapping:
- P -> 7
- A -> 4
- I -> 1
- N -> 2
- T -> 8

- Applying the same logic to ACCEPT:
- A -> 4
- C -> 5
- E -> 5
- P -> 7
- T -> 8

- So, the code for ACCEPT is 455978, which corresponds to option A.

From the final arrangement, we get T faces Q.
Hence, Option C is correct.
References:
Q sits second to the right of P.
Inferences:
From the above reference, we get two different cases:
In case 1, P sits at the corner or in the middle of the side of the table.

References:
R is not an immediate neighbor of P.
R faces inside.
R sits third to the left of W.
Inferences:
From the above references, we get different cases for R, in case 1(a) in which R faces P and in case 1(b) R faces Q.

References:
T sits third to the left of U.
V sits second to the left of U.
Inferences:
So, from this case 1(b) and case 2 will be eliminated as there is no possible place for V in these cases after placing U and T. Hence, we get our final arrangement in which S sits on the immediate left of P and V sits on the immediate right of R.
Final arrangement:

Checking Statement I:

Using the above reference, we get the following arrangement:

Clearly, W is sitting second to the right of U.

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

Checking Statement II:

Using the above references, we get the following arrangement:

Clearly, W is sitting second to the right of U.

Hence data in statement II is sufficient to answer the question.

Here, the data in either Statement I or II alone is sufficient to answer the question.

Hence, Option C is correct.

Given:

Distance travelled by the object in 4 sec = 24 m

Distance travelled by the object in 2 sec = 15 m

Formula used:

Distance = Speed × time

Average speed = Total distance/Total time

Calculation:

Total distance travelled by the object = 24 + 15 = 39 m

Total time taken = 4 + 2 = 6 sec

Average speed = 39/6 

⇒ 6.5 m/s

∴ The average speed of the object is 6.5 m/s.

Carpenter, Plumber, Electrician and Blacksmith are in same working category.

User-level threads

User-level threads are very effective because a mode switch is not required to switch from one thread to another. Here is a detailed explanation:

• Definition: User-level threads are managed by the application without the intervention of the operating system. They are created and scheduled by the application itself.


• Advantages: User-level threads offer several advantages, including:




• No mode switch: User-level threads do not require a mode switch from user mode to kernel mode when switching between threads. This makes the context switch faster and more efficient.


• Thread management control: The application has full control over thread management, including scheduling, synchronization, and resource allocation.


• Portability: User-level threads can be easily ported across different operating systems, as they are independent of the underlying kernel.




• Disadvantages: User-level threads also have some limitations:




• Blocking system calls: If a user-level thread performs a blocking system call, it will block the entire process, as the kernel is unaware of the individual threads.


• Limited parallelism: User-level threads may not fully utilize the available hardware resources, as the operating system schedules threads at the process level rather than at the thread level.

In conclusion, user-level threads are very effective because they eliminate the need for a mode switch and provide greater control over thread management. However, they also have some limitations that need to be considered in certain scenarios.

The correct answer is Option 3.

Retaining Information when Power is Turned Off:
ROM (Read-Only Memory)
- ROM is a non-volatile memory type that retains data even when the power is turned off.
- It contains firmware or software instructions that are permanently stored during manufacturing.
- The data stored in ROM is not easily modified or erased, hence the name "read-only."
CPU (Central Processing Unit)
- The CPU is the brain of the computer that performs calculations and executes instructions.
- It does not retain any data when the power is turned off.
- The CPU relies on other storage devices, such as RAM and ROM, to store and retrieve data.
DRAM (Dynamic Random-Access Memory)
- DRAM is a type of volatile memory that requires constant power to retain data.
- When the power is turned off, the stored data in DRAM is lost.
- DRAM is commonly used as the main memory in computers due to its fast access times.
DIMM (Dual In-Line Memory Module)
- DIMM is a physical component that houses memory modules, such as RAM or ROM.
- It does not retain any data when the power is turned off.
- The data stored in DIMM is stored in the memory modules it houses, which may be either volatile (e.g., RAM) or non-volatile (e.g., ROM).
Conclusion:
Of the options provided, only ROM (Read-Only Memory) retains the information it's storing when the power to the system is turned off.
