A turning green with China rose indicator suggests that it is a basic solution. China rose indicator is a pH indicator that changes color in the presence of acidic and basic solutions. In this case, the green color indicates that solution A has a basic nature.

B remaining colorless with China rose indicator suggests that it is a neutral solution. The lack of color change indicates that solution B has a pH value close to 7, which is considered neutral on the pH scale.

C turning dark pink in color with China rose indicator suggests that it is an acidic solution. China rose indicator turns pink or dark pink in the presence of acidic solutions, indicating that solution C has an acidic nature.

AB || CD and t transversal intersects them at E and F
∠BEF + ∠EFD = 180° (co-interior angles)

⇒ ∠FEG + ∠EFG = 90°
In Δ GEF
∠EGF + ∠FEG + ∠EFG = 180°
∴ ∠EGF + 90° = 180°
∴ ∠EGF = 90°.
The above result can be restated as :
If two parallel lines are cut by a traversal, then the bisectors of the interior angles on the same side of the traversal intersect each other at right angles.

Combined weight of the group increases by = 2 × 15 = 30 kg

Let's check each option:
(i) x:y::z:x → This doesn't follow the pattern of a proportion.
(ii) x:y::y:z → This follows the pattern of a proportion.
(iii) x:y::z:y → This doesn't follow the pattern of a proportion.
(iv)  x:z::y:z → This doesn't follow the pattern of a proportion.
Therefore, the answer is (b).

(100 – 37.50)% of total employees = 450
62.50% of total employees = 450

 a = -3 and a(2) = 4
a = -3
d = 4 - a = 4 - (-3) = 7
a(21)=a + (21-1) x d
= -3 + (20) x 7
= -3 + 140
= 137

There are 8 triangles in the figure. By counting the individual triangles, we can see that there are 2 large triangles, 4 medium triangles, and 2 small triangles, making a total of 8 triangles.

According to question,
A's weight is twice as much as of B.
1. A = 2B.
B's weight is four and half times as much as of C.
2. B = 4.5C
C's weight is half times as much as of D.
3. C = D/2.
D's weight is half as much as of E.
4. D = E/2.
E weight is less than A but more than C.
5. A > E > C
from 1 and 2
6. A = 2B = 9C
from 6 and 3
7. A = 2B = 9C = 4.5D
from 7 and 4
8. A = 2B = 9C = 4.5D = 2.25E
so from 8 and 5
A > B > E > D > C

So A is the heaviest in the weight.

As Cloth is made in a Mill, similarly Newspaper is printed in press.

Final Arrangement:

Common Explanation:
References:
1. Two people are sitting between A and Z.
2. C sits fourth to the right of Z.
3. The number of people sitting to the right of A is the same as the number of people sitting to the left of Z.
4. The number of people sitting between A and C is the same as the number of people sitting between X and C.
5. X is an immediate neighbour of D, who sits on one of the ends.
6. The number of people sitting between D and C is the same as the number of people sitting between C and Y.
7. At most 25 people are sitting in a row.
Inferences:
From reference 1, we get two possible cases.
From reference 7, case2 was eliminated.
Hence, Case 1 is the final arrangement.

Dos

. DOS (Disk Operating System) is not a requirement of the internet. Here is a detailed explanation of why each of the other options is a requirement:
A: Operating System
- An operating system is required to run the necessary software and manage hardware resources on a computer. It provides the foundation for running internet-related applications and services.
C: Web browser
- A web browser is essential for accessing and viewing websites on the internet. It interprets HTML, CSS, and JavaScript code to display web pages and allows users to navigate through different websites.
D: Modem
- A modem is used to connect a computer or other device to the internet. It converts digital data from the computer into analog signals that can be transmitted over telephone lines or other communication channels. The modem at the receiving end then converts the analog signals back into digital data.
In summary, while an operating system, web browser, and modem are all requirements for accessing and using the internet, DOS is not necessary for internet connectivity.

To determine the size of a monitor, we measure the screen diagonally, from the top left corner to the bottom right corner. Here's a detailed explanation:
Diagonal Measurement:
- The size of a monitor is typically measured diagonally because it provides an accurate representation of the screen's actual size.
- The diagonal measurement is obtained by measuring the distance from the top left corner of the screen to the bottom right corner in a straight line.
- This measurement helps us understand the physical size of the screen and is commonly used to compare and select monitors.
Other Measurements:
- While diagonal measurement is the standard for determining monitor size, other measurements are also important for specific purposes.
- Vertical measurement refers to the distance from the top to the bottom of the screen, which is essential for understanding the screen's height.
- Horizontal measurement refers to the distance from the left to the right of the screen, which helps in determining the screen's width.
- However, these measurements alone do not provide a comprehensive understanding of the monitor's size.
Conclusion:
In conclusion, the size of a monitor is determined by measuring the screen diagonally, from the top left corner to the bottom right corner. This measurement provides an accurate representation of the screen's size and is commonly used for comparing and selecting monitors.

The operating system is also called the Interface between the user and the computer.
Explanation:
- An operating system is a software that manages computer hardware and software resources and provides common services for computer programs.
- It acts as an intermediary between the user and the computer, allowing the user to interact with the computer hardware and software.
- The operating system provides a user-friendly interface that enables users to perform various tasks and access computer resources easily.
- It translates user commands and instructions into a language that the computer can understand and execute.
- The operating system also manages and allocates system resources such as memory, processing power, and input/output devices.
- It allows users to run multiple programs simultaneously and ensures that they do not interfere with each other.
- The operating system also handles system errors, manages file systems, and provides security features to protect the computer and user data.
- Overall, the operating system serves as a bridge between the user and the computer, enabling efficient and effective communication and interaction.
