From the common explanation, we get C sits opposite to F.

Hence, Option C is correct.

Common Explanation:

References:

One person sits between A and C, who sits second to the right of H.

G sits opposite to B.

Both G and B do not sit immediate left of H.

Inferences:

From the above reference, we get two different cases:

References:

D sits second to the left of B.

A doesn’t sit beside D.

E doesn’t face C.

Inferences:

From the above reference, case 1 will be eliminated because A doesn’t sit beside of D.

So, the final arrangement:

From the common explanation, we get (C, L) sits at the extreme corner of the table.

Hence, Option D is correct.

Final Arrangement:

Common Explanation:

References:

J sits fourth to the right of O and N sits second to the left of J.

Only H sits between J and G.

Inferences:

From the above references, we get

References:

Only D sits between G and C

G is not an immediate neighbour of J but fifth to the right of I.

M, who sits exactly in the middle, is second to the right of I.

Five persons sit between L and J.

Inferences:

From the above references, we get

References:

E is not an immediate neighbour of N.

Inferences:

From the above reference, we get the final arrangement:

As 'Calf' is the youngest of 'Cow' similarly 'Kitten' is the young one of 'Cat'.

Following the common explanation, we get “C and Z sits two places away from Y”.
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 Statement I:
O runs faster than N but slower than L. P runs slower than N but is not slowest runner.
L > O > N > P > M
Here, N is the third faster runner.
From Statement II:
M runs slower than N. L runs faster than N and P. O runs faster than only M.
L > N/P > P/N > O > M
Here, either N or P is the third faster runner.
So, the data in Statement I alone is sufficient to answer the question while the data in Statement II is not sufficient to answer the question.
Hence option A is correct.

Utility, in ordinary sense, means usefulness. But, in economics, it means want-satisfying power of a commodity or service — the power to satisfy a human want. Utility is addable. One can add utility obtained from each unit of a commodity to get total utility obtained from the entire stock. In other words, by adding marginal utility from successive units, we obtain total utility of the stock.

Factors that helped Shivaji in his raids:
1. The gradual decline of the Portuguese power on the western coast:
- The Portuguese had been a dominant force on the western coast, but their power was gradually declining during Shivaji's time.
- This decline weakened their ability to resist Shivaji's raids and allowed him to exploit their weak defenses.
2. The able assistance of Bijapur and Golcunda:
- Shivaji received support from the Sultanates of Bijapur and Golcunda in his raids.
- These Sultanates were rivals of the Mughals and saw Shivaji as a valuable ally against the Mughal Empire.
- Their assistance provided Shivaji with additional resources and manpower, increasing his chances of success in his raids.
3. Mughal preoccupation with the Afghan uprising in the northwest:
- The Mughal Empire was facing a significant challenge in the form of an Afghan uprising in the northwest region.
- This preoccupation with internal conflicts diverted their attention and resources away from dealing with Shivaji's raids.
- Shivaji took advantage of this situation and launched his attacks on the Mughal provinces of Berar, Baglana, and Khandesh.
4. None of these:
- This option is incorrect as there were clear factors that helped Shivaji in his raids, as mentioned above.
In conclusion, the factors that helped Shivaji in his raids include the decline of Portuguese power, assistance from Bijapur and Golcunda, and the Mughal Empire's preoccupation with the Afghan uprising. These factors created favorable conditions for Shivaji to successfully carry out his raids.

Collateral provides a level of assurance to the lender and reduces the risk associated with lending, making it a common practice in credit agreements.

Explanation:

• Assertion (A): The RBI supervises the functioning of formal sources loans in India.


• Reason (R): RBI is authorised to issue currency notes.

Detailed

• Assertion (A) is true: The Reserve Bank of India (RBI) is the central bank of India and it plays a crucial role in supervising the functioning of formal sources of loans in the country. It regulates and supervises the banking sector, including banks and financial institutions, to ensure stability and efficiency in the financial system.


• Reason (R) is true: The RBI is indeed authorized to issue currency notes in India. It is the sole authority responsible for the issuance and distribution of currency notes in the country. This power is granted to the RBI under the Reserve Bank of India Act, 1934.


• Explanation of the relationship between A and R: While both the assertion and reason are true, the reason does not directly explain why the RBI supervises the functioning of formal sources of loans in India. The issuance of currency notes is just one of the many responsibilities of the RBI, and its supervision of formal sources of loans is a separate function aimed at ensuring the stability and regulation of the financial sector.


• Therefore, option B: Both A and R are true but R is not the correct explanation of A is the correct choice in this case.

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).
