• The chemical compound phenolphthalein has the formula C₂₀H₁₄O₄ and is commonly abbreviated as "HIn" or "phph" in shorthand notation.
• Phenolphthalein is frequently used as an indicator.
• It's a phthalein dye, which means it's a type of dye.
• Phenolphthalein in Acidic solutions turns colourless
• Phenolphthalein in basic solutions turns pink in colour. 

Explanation:

• Lime water is basic in nature. 
• Calcium hydroxide is the chemical term for lime water, which has the formula Ca(OH)₂.
• When Phenolphthalein, it turns pink as lime water is basic in nature.

∠DAC = ∠B + ∠C
(Exterior angle prop. of a Δ ABC)
According to question,
130° = 2A + 3A
5A = 130°
A = 26°
∴ ∠B = 52°; ∠C = 78°

A ratio equivalent to 3 : 7 is:
To find a ratio equivalent to 3 : 7, we need to find a pair of numbers that have the same ratio when simplified. Let's try the options:

(i) 3 : 9 → This simplifies to 1 : 3, not the same as 3 : 7
(ii) 6 : 10 → This simplifies to 3 : 5, not the same as 3 : 7
(iii) 9 : 21 → This simplifies to 3 : 7, which is the same as 3 : 7, so the answer is (iii).

80% of B = 125% of C
Efficiency → B : C = 125 : 80 = 25 : 16
Time → B : C = 16 : 25

Hence, Option C is correct.

Let the number be x. Then,

We know that: 
LCM is the least common multiple of the given numbers whereas HCF is the highest common factor of those numbers.
Then, LCM is the multiplication of one common factor of the numbers and the other different factors of the numbers.
Write the LCM = 120 into factored form, that is
120 = 2 × 2 × 2 × 3 × 5
= 4(2 × 3 × 5)
⇒ 4 is the common factor of the numbers.
So, the HCF of three numbers is a multiple of 4.
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, ...
Therefore, 35 is not the multiple of 4, then 35 cannot be their HCF.

x : y = 75 : 100

Hence, Option C is correct.

Let AB be the light house and the two boats be at C and D

∴ AB = 125 m

tan30° = BC/AB = x/125 = 1/3

=> x = 72.17 m

tan45° = BD/AB = y/125 = 1

=> y = 125 m

∴ The distance between the two boats is = x + y

= 72.17 + 125

= 197.17 m

πr² + 2πr = 704
πr(r + 2) = 704

r × (r + 2) = 224
r = 14
So the answer

Hence, Option C is correct.

Following the common explanation, we get “C is the immediate neighbor of X”.
Hence, option D is correct.
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.

From the common explanation, we get “L is second to the left of O.
Hence, Option B is correct.
Final Arrangement:

Common Explanation:
References:
There are two persons between P and K, who is to the right of P.
R is adjacent to K and O.
M, who is the immediate right of K, is second to the left of P.
Inferences:
From the above reference, we get the final arrangements:

From Statement 1:
A’s rank is five ranks below H's rank, whose rank is 19^th from the bottom.

Here, A’s rank is 10^th from the top.
From Statement 2:
A’s rank is seven ranks above F's rank, whose rank is 11^th from the bottom.

Here, A’s rank is 6^th from the top.
Hence option C is correct.

1st term = 24
2nd term = 24 + [6 x (6 + 0)] = 60
3rd term = 60 + [6 x (6 + 4)] = 120
4th term = 120 + [6 x (6 + 9)] = 210

Thus, the missing term is 5th term = 210 + [6 x (6 + 15)] = 210 + 126 = 336

Answer:
The correct answer is option C: JavaScript. JavaScript is a client-side programming language and is not typically used for server-side programming. Here is a detailed explanation:
Server-side programming languages:
- JSP (JavaServer Pages): JSP is a server-side scripting language that is used to create dynamic web pages. It is based on Java programming language and allows embedding Java code within HTML.
- ASP (Active Server Pages): ASP is a server-side scripting language developed by Microsoft. It allows embedding scripting code within HTML and is mainly used to create dynamic web pages on Windows servers.
- PHP: PHP is a popular server-side scripting language that is widely used for web development. It is embedded within HTML and can be used to perform various server-side tasks such as generating dynamic content, interacting with databases, and handling form data.
Client-side programming language:
- JavaScript: JavaScript is a programming language that is executed on the client-side (i.e., on the user's web browser). It is mainly used for enhancing the interactivity and functionality of web pages. JavaScript can manipulate the Document Object Model (DOM), handle user events, and perform client-side validations.
In summary, JavaScript is not a server-side programming language and is primarily used for client-side scripting.

The protocol that provides virtual terminal in the TCP/IP model is Telnet.
Telnet:
- Telnet is a network protocol that allows users to remotely access and control a virtual terminal over a TCP/IP network.
- It provides a command-line interface that enables users to execute commands and interact with remote hosts as if they were directly connected to them.
- Telnet uses TCP as the underlying transport protocol to establish a reliable connection between the local and remote hosts.
- It operates on port number 23 and sends data in clear text format, which means it is not secure for transmitting sensitive information.
- Telnet allows users to remotely manage devices, troubleshoot network issues, and administer systems without physically being present at the location.
Other options:
- SMTP (Simple Mail Transfer Protocol) is a protocol used for sending and receiving email messages.
- HTTP (Hypertext Transfer Protocol) is a protocol used for transmitting web pages and other resources over the internet.
- None of these options provide a virtual terminal functionality in the TCP/IP model.
Therefore, the correct answer is Telnet (option A).

Statement (i): An address with all bits 1 is interpreted as all networks or all hosts.

• This statement is true.


• An address with all bits 1 is known as the broadcast address.


• When this address is used, it is interpreted as a request to send data to all networks or all hosts within a network.


• For example, in a network with an IP address of 192.168.1.0 and a subnet mask of 255.255.255.0, the broadcast address would be 192.168.1.255.

Statement (ii): The class A network 128.0.0.0 is defined as the loopback network.

• This statement is false.


• The loopback network is defined as 127.0.0.0/8, not 128.0.0.0.


• The loopback address 127.0.0.1 is used to test network connectivity on a local machine.


• It is commonly used for troubleshooting and is not assigned to any physical network interface.

Therefore, the correct answer is (i) only.

The distance from one pixel to the next pixel is called resolution.
Explanation:
The resolution of an image refers to the number of pixels (individual points of color) contained in that image. It determines the level of detail and clarity in the image. The higher the resolution, the more pixels there are per unit of area, resulting in a sharper and more detailed image.
Key Points:
- Resolution is a measure of pixel density.
- It determines the level of detail and clarity in an image.
- The distance from one pixel to the next pixel is determined by the resolution.
- Higher resolution results in a sharper and more detailed image.
- Resolution is commonly measured in pixels per inch (ppi) or dots per inch (dpi).
- The higher the resolution, the smaller the distance between pixels.
Therefore, the correct answer is A: Resolution.
