India's weightage in the MSCI Global Standard (Emerging Markets) index has surged to a historic high of 18.2% after MSCI's February review, nearly doubling since November 2020. This increase is attributed to factors like standardized foreign ownership limits, sustained domestic equity rally, and relative underperformance of other emerging markets, particularly China.

Using Rule 1 :
1st number × 2nd number = L.C. M. × H.C.F,
First number × Second number = HCF × LCM

X × 32 + 8 – 40  = X × 30
2X = 32
X = 16
Hence, Option A is correct.

4’s multiples are:
12, 16, 20, 24, …
a = 12 and d = 4
2 is the remainder for 250 / 4.
250 – 2 = 248 which is divisible by 2.
12, 16…248
nth term, a(n) = 248
a(n) = a + (n − 1) x d
248 = 12 + (n-1) × 4
236 / 4 = n - 1
59 = n - 1
n = 60

Bigger number : Smaller number = 27 : 20

Hence, Option B is correct.

Population in 2022

So the answer = 68,400 – 60,000 = 8,400
Hence, Option C is correct.

Let the numbers be 23x and 23y where x and y are co-prime.
∴ LCM = 23 xy
As given,
23xy = 23 × 13 × 14
∴ x = 13, y = 14
∴ The larger number = 23y
= 23 × 14 = 322

As we know that the angles are supplementary so sum of angles will be 180 degree.
Let us assume that the ratio factor is r.
According to question,
Angles are supplementary and have a ratio of 1:4.
r + 4r = 180
⇒ 5r = 180
⇒ r = 180/5
⇒ r = 36

The logic follows here : 
1. Sukhoi Su-30MKI is a Fighter Jet.
2. INS Vikrant is different from these two, it is an Aircraft Carrier.

The least possible Venn diagram for the given set of words is :

Hence, the correct answer is "Option (4)".

From the diagram given below:

The shaded part represents the persons who speak only two languages.

26 + 51 + 17

= 94 

Hence, the correct answer is "94".

The logic that follows here is 

1) D is sitting to the immediate left of A.

2) C is sitting to the immediate right of B.

3) B is not sitting adjacent to A.

The final seating arrangement will be

Second to the right of D is 'E'.

Hence, the correct answer is E.

All conditions are as follows;

 

Rakul doesn't fulfill the necessary conditions for any post.

Thus he is not eligible for any post.

Hence, the correct answer is "Option 2".

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

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

From the common explanation, we get Aarti sits third to the right of Kirti.

Hence, Option D is correct.

Final Arrangement:

Common Explanation:

References:

Eight students Kirti, Ayushi, Manu, Sona, Aarti, Bobby, Ankita and Divya are sitting around the square table.

Four students sit on each side while rest on each corner.

Students at the side face away from the centre and students at the corner faces towards the centre.

Inferences:

So, we need to arrange as follows to accommodate the information as stated in the question,

References:

Divya sits third to the left of Ayushi.

Kirti sits opposite to Manu and both faces away from the centre.

Inferences:

From the above references, we get the following two different cases:

Case 1:

Case 2:

References:

Neither Kirti nor Manu are beside Ayushi.

Sona sits immediate left of Ankita, who sits on the side of the table.

Bobby is not an immediate right of Ayushi.

Bobby is not adjacent to Manu.

Inferences:

So, from this case 2 will be eliminated as neither Kirti nor Manu are beside Ayushi.

Now, from case 1 we get the following final arrangements:

As 24:60 = (2/5)

Similarly, (120/300) = (2/5)

Explanation:

• Identifying the missing word: We need to find the word that fits best in blank number 14 based on the context provided.


• Understanding the context: The sentence talks about ancestors punishing individuals who failed in their duty, indicating that those individuals were chastised by the ancestors.


• Analysis: The word "who" is the most appropriate choice for blank number 14 as it refers to individuals (people) who failed in their duty.


• Conclusion: Therefore, the correct answer is option A: who.

One meaning of fathom is to comprehend, and hence misconstrue is the closest antonym.

Routing in OSI Network Architecture

Answer: B. Data link layer

Explanation:

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven different layers. The routing process, which involves the selection of the best path for data packets to travel from the source to the destination, is primarily performed by the network layer in the OSI model. However, the data link layer also plays a role in routing by facilitating the transmission of data between directly connected nodes or devices. Here's a breakdown of the routing process in the OSI model:

1. Network Layer:

• The network layer is responsible for logical addressing, routing, and path determination.


• It receives data from the transport layer and adds network layer headers to create packets.


• It determines the best path for packet transmission based on the destination address and network conditions.


• It uses routing protocols (such as OSPF, RIP, BGP) to exchange routing information and build routing tables.


• It forwards packets to the next hop or the next network based on the routing table.

2. Data Link Layer:

• The data link layer provides reliable point-to-point communication between directly connected nodes.


• It encapsulates the network layer packets into data frames and adds data link layer headers and trailers.


• It performs error detection and correction using techniques like CRC (Cyclic Redundancy Check).


• It controls the flow of data between devices to avoid congestion.


• It uses MAC (Media Access Control) addresses to identify devices on the same network.


• It performs local network routing by forwarding data frames to the appropriate device based on MAC addresses.

While the primary responsibility of routing lies with the network layer, the data link layer contributes to the routing process by facilitating communication between directly connected devices. Therefore, in the OSI network architecture, routing is performed by both the network layer and the data link layer.

Email (electronic mail) is the exchange of computer-stored messages from one user to one or more recipients via the internet.

Refresh Buffer on a Color Monitor
The refresh buffer on a color monitor is also known as the pixmap. The pixmap is a memory area that holds the pixel data for the current frame being displayed on the screen. When the refresh buffer is updated, the changes are reflected on the screen, creating a smooth and continuous display.
Key Points:
- The refresh buffer, or pixmap, contains the pixel data for the current frame on the color monitor.
- It is a memory area that holds the information needed to display the image on the screen.
- The refresh buffer is constantly updated to create a smooth and flicker-free display.
- By refreshing the buffer at a high rate, typically 60 times per second, the image appears to be continuously displayed to the viewer.
- The pixmap is typically stored in a specific format, such as RGB (Red Green Blue), to accurately represent the colors on the screen.
- The refresh buffer is an essential component of a color monitor, allowing for the dynamic and vibrant display of images and videos.
In conclusion, the refresh buffer on a color monitor is also called the pixmap, which is responsible for holding the pixel data for the current frame being displayed on the screen. It plays a crucial role in creating a smooth and continuous display for the viewer.
