NVS Junior Secretariat Assistant Mock Test - 3 - NVS TGT/PGT MCQ

Q, R, S, T, U, and V are seated in a straight line facing North.

i) S is second to the right of T.

ii) T is second to the right of Q.

iii) R is to the immediate left of Q

iv) R is to the immediate left of Q and is second to the left of V.

Thus we can see Q is sitting Fourth to the left of S.

Hence, the correct answer is "Option 4".

Let the numerator = x and denominator = y

y + 3 = 2y ⇒ y = 3

x +1= 3 ⇒ x = 2

∴ xy = 2 × 3 = 6

Step 1: Determine Sunny's Work Rate

• Sunny's Completion Time: 15 days to complete the work.
• Sunny's Work Rate:
  • Sunny can complete 1 work in 15 days.
  • Therefore, Sunny's work rate is 1/15 work per day.

Step 2: Calculate Bobby's Work Rate

• Bobby's Efficiency: Bobby is 60% as efficient as Sunny.
• Convert Efficiency to Fraction:
  • 60% = 60/100 = 3/5.
• Bobby's Work Rate:
  • Bobby's rate = (3/5) * (1/15) = 3/75 = 1/25 work per day.

Step 3: Determine the Number of Days Bobby Takes to Complete the Work

• Total Work: 1 work.
• Bobby's Daily Contribution: 1/25 work per day.
• Number of Days Required:
  • Days = Total Work / Bobby's Work Rate = 1 / (1/25) = 25 days.

Let AB be the building and AC be its shadow.
Then, AC = 20m and ∠ACB = 60°. Let AB = x m.
Presently AB/AC = tan 60° = √3 => x/10 = √3
=> x = 10√3m = (10 * 1.732) m = 17.32m.
∴ Height of the building is 17.32m.

a(18) – a(14) = 32
a(n) = a + (n – 1) x d
a + (17) x d – (a + 13 x d) = 32
(17) x d – (13) x d = 32
(4) x d = 32
d = 8

Product of two numbers = HCF × LCM
1280 = 8 × LCM
160 = LCM

When installing a peripheral, you also usually need to install a ______.

The correct answer is driver.

Explanation:

When installing a peripheral, such as a printer, scanner, or external hard drive, it is necessary to install a driver. A driver is a software program that allows the peripheral to communicate with the computer's operating system and enables the computer to recognize and utilize the peripheral's features and functions.

Here are some key points to remember:

• Peripheral: A peripheral is an external device that connects to a computer, such as a printer, scanner, mouse, keyboard, or external storage device.


• Driver: A driver is a software program that acts as a bridge between the peripheral and the computer's operating system. It provides the necessary instructions and protocols for the operating system to communicate with the peripheral.


• Installation: To install a peripheral, you typically follow these steps:




• Connect the peripheral to the computer using the appropriate cables or wireless connection.


• Insert the installation disc provided with the peripheral into the computer's disc drive, or download the driver software from the manufacturer's website.


• Run the installation program and follow the on-screen instructions.


• Once the driver is installed, the computer should recognize the peripheral and it will be ready for use.

Remember to always install the correct driver for your specific peripheral and operating system version to ensure compatibility and optimal performance.

To return the desired result "MCQ@ Questions" in cell C1, you can use the CONCATENATE function or the ampersand (&) operator in Excel.
Here is the detailed solution:
1. The correct function to use in this case is the CONCATENATE function or the ampersand (&) operator.
2. The CONCATENATE function allows you to join multiple text strings together. It takes multiple arguments and concatenates them into a single string.
3. The ampersand (&) operator also performs the same function as the CONCATENATE function and joins text strings together.
4. In this case, you want to join the value in cell A1 ("MCQ") with the text string "@" and the value in cell B1 ("Questions").
5. To achieve this, you can use the following formula in cell C1:
=CONCATENATE(A1, "@", B1) or =A1 & "@" & B1
This formula will concatenate the text in A1, the "@" symbol, and the text in B1, resulting in the desired output "MCQ@ Questions" in cell C1.
Therefore, the correct answer is option C: =A1 & "@" & B1.

The program that interacts with the inner part called kernel is known as Shell. Here is a detailed explanation:
Definition:
The Shell is a program that acts as an interface between the user and the operating system kernel. It allows users to interact with the operating system by executing commands and managing the system resources.
Key Points:
- The Shell provides a command-line interface (CLI) or a graphical user interface (GUI) for users to interact with the operating system.
- It interprets the commands entered by the user and executes them by communicating with the kernel.
- The Shell handles input/output redirection, command execution, file management, and other system operations.
- It provides features like command history, command completion, and scripting capabilities.
- Different operating systems have different types of shells, such as Bash (Bourne Again SHell) on Linux, PowerShell on Windows, and Terminal on macOS.
- The Shell also allows users to run scripts, which are sequences of commands stored in a file.
- It acts as an intermediary between the user and the kernel, translating user commands into instructions that the kernel can understand and execute.
Example:
Let's say a user wants to create a new directory. They can use the Shell by typing a command like "mkdir new_directory". The Shell will interpret this command and send a request to the kernel to create the directory. The kernel will then carry out the requested operation and inform the Shell of the result. The Shell will then display the appropriate message to the user.
Therefore, the correct answer is D: Shell.

A bootstrap is:

• Definition: A bootstrap is a small initialization program that starts up a computer system. It is responsible for loading and executing the operating system or other software components necessary for the system to function.


• Function: The bootstrap program resides in the computer's firmware or read-only memory (ROM) and is automatically executed when the system is powered on or restarted.


• Initialization: The bootstrap program initializes the hardware components of the computer, such as the processor, memory, and input/output devices.


• Bootloader: The bootstrap program then loads and executes a more complex bootloader, which further initializes the system and loads the operating system or other software from storage devices, such as hard drives or solid-state drives.


• Chain of Execution: The bootstrap process involves a chain of execution, where each component in the chain is responsible for loading and executing the next component until the operating system is fully loaded and running.


• Importance: The bootstrap program is crucial for the proper functioning of a computer system as it ensures that the necessary software is loaded and executed in the correct order.

In summary, a bootstrap is a small initialization program that starts up a computer system by loading and executing the necessary software components, such as the operating system. It plays a critical role in the boot process and ensures the proper functioning of the system.
