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.

Under Montagu-Chelmsford reforms, education was shifted to provincial ministries. The government stopped taking a direct interest in educational matters, while government grants, liberally sanctioned since 1902, were now stopped. Financial difficulties prevented any substantial expansion, but still, education grew, especially under philanthropic efforts.

The Government of Nepal  is an executive body and the central government of Nepal. Prior to the abolition of the Nepali monarchy in 2008, it was officially known as His Majesty's Government.

The head of state is the President and the Prime Minister holds the position of the Head of executive. The role of President is largely ceremonial as the functioning of the government is managed entirely by the Prime Minister who is appointed by the Parliament.

The heads of constitutional bodies are appointed by the President on the recommendation of the Constitutional Council, with the exception of the Attorney General, who is appointed by the President on the recommendation of the Prime Minister.

Explanation of the Iqta system:

• Grant of taxation over lands: The Iqta system was a system of land distribution in the medieval Islamic world where officials were given control over land in exchange for military or administrative services. This was a grant of taxation over lands.


• Role of Muqti: The officer holding the charge of a large iqta was known as a Muqti. The Muqti was responsible for collecting revenue from the land and ensuring its proper administration.


• Significance of Iqta: The iqta was a piece of landed property received by a person from the state. It signified 'revenue assignments' and was a way for the state to compensate officials for their services.


• Conclusion: Therefore, all of the above statements regarding the Iqta system are correct. It was a grant of taxation over lands, the officer holding the charge of a large iqta was known as Muqti, and the iqta signified revenue assignments.

Explanation:

• Embargo on imports from India: The Roman senate laid an embargo on the import of Muslin from India as it was considered a menace to the city's morals.


• Reasoning behind the embargo: Muslin was a luxurious fabric that was highly sought after by the Roman elite. However, the sheer and delicate nature of Muslin was believed to be provocative and immoral.


• Impact on the city: The Roman senate believed that the availability of Muslin in the city would lead to moral decadence and corrupt the values of the citizens.


• Alternative imports: In order to maintain the moral integrity of the city, the Roman senate restricted the import of Muslin and looked for alternative fabrics that were deemed more appropriate for the society.

The Elichpur clan was a feudatory of the Badami Chalukyas, and during the rule of Dantidurga, it overthrew Chalukya Kirtivarman II and went on to build an empire with the Gulbarga region in modern Karnataka as its base.

The word Noise comes from the Latin word “nausea”. Noise pollution is referred to as an undesirable sound that causes uneasiness to the ear and can result in serious health hazards. Noise pollution can be classified into indoor and outdoor sources.

• Indoor Sources: They include noise produced from radio, television, generators, lawn mowers, electric fans, air coolers, air conditioners, different home, and kitchen appliances, etc.
• Outdoor Sources: They include noise from loudspeakers, industrial activities, automobiles, rail traffic, aeroplanes, farm machines, pump sets, etc.

Key Points

• ​Noise pollution around the educational area can negatively affect the performance of both teachers and students. Noise pollution in the school's environment occurs due to many sources.
• It depends on where the school is built. A school which is located near the city center has a very high noise pollution range because it has many sources that will lead to noise pollution.
• In large residential areas, the sources of noise pollution are limited but in some cases, it still leads to noise problems. The schools must be located in a quiet environment.
• Noise in classrooms can lead to stress and teacher has to raise their voice louder. Hence, teachers teach children to remain quiet in the class and maintain proper silence while learning so that the teacher can teach effectively.

Hence, it is concluded that by maintaining silence in and around the school helps to prevent noise pollution in or around the school.

Every country that is a democracy gives rights to its citizens. In a democracy, every citizen has the right to vote and the right to be elected. For democratic elections to take place, it is necessary that citizens should have the right to express their opinion, form political parties and take part in other political activities.

Both are pairs of antonyms.
Hence, Option A is correct.

As per the given information;

Distance between S and P = √(PQ² + QS²)
SP = √(6² + 8²)
SP = √(36 + 64)
SP = √100
SP = 10 km
Hence, S is 10 km in South-East with respect to P.

Four friends W, X, Y and Z are students of Class 10th.

i) W and X are good in Hindi but poor in English.

ii) W and Y are good in Science but poor in Mathematics.

iii) Y and Z are good in English but poor in Social Studies.

iv) Z and X are good in Mathematics as well as in Science.

Thus we can see W is not good in Mathematics but good in Hindi.

Hence, the correct answer is "W".

By using the symbols in the table given below, we can draw the following family tree:

We do not know the gender of Shanti. 
Clearly, Shaurya is the cousin of Karan.
Hence, ‘Cousin’ is the correct answer.

The logic followed is:

Abduct and Kidnap are synonyms.

Similarly,

Fierce and Violent are synonyms.

Hence, the correct answer is "Violent".

In the question,

11² = 121

13² = 169

17² = 289

19² = 361

23² = 529

24² = 576

Thus we can say except for (24)² , all the given number is a square of a prime number.

Hence, Option (2) is correct.

From Statement I:

From this statement, we get the following ranking.

Person in the row = 8 persons + Akansha + 4 persons + Rhea + 7 persons + Harshita + 8 persons

So, we get that Rhea is 17th from the bottom in the class.

Clearly, Statement I alone is sufficient to answer the question.

From Statement II:

From this statement, we get the following ranking.

Person in the row = 11 persons + Yamini + 13 persons + Rhea + 4 persons

So, we get that Rhea is 5th from the bottom in the class.

Clearly, Statement II alone is sufficient to answer the question.

Clearly, Either Statement I or Statement II alone is sufficient to answer the question.

Hence, option C is the correct answer.

Complement of 30°20′ = 90° – ( 30°20′ ) = 90° – ( 30° + 20′ )
= (89° – 30°) + (1° – 20′)
= 59° + 60′ – 20′ [ ∴ 1° = 60°′]
= 59° + 40′ = 59°40′.

By increasing his speed by 25%, he will reduce his time by 20%. (This corresponds to a 6 minute
drop in his time for travel—since he goes from being 10 minutes late to only 4 minutes late.)
Hence, his time originally must have been 30 minutes. Hence, the required distance is 20 kmph ×
0.5 hours = 10 km.

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.

We have to find the least number that is divisible by all numbers from 1 to 10. 

∴ LCM (1 to 10) = 2³ × 3² × 5 × 7 = 2520 

Thus, 2520 is the least number that is divisible by every element and is equal to the least common multiple.

∴ STOLL → $2@33
Hence, option B is correct.

The average of the last two numbers

Hence, Option A is correct.

The A.P. is -3, -1/2, 2 …
Where a = – 3
d = a(2) – a(1) = (-1 / 2) - (-3)
⇒ (-1 / 2) + 3 = 5 / 2
a(n) = a + (n−1) x d
a(11) = 3 + (11-1) x (5 / 2)
a(11) = 3 + (10) x (5 / 2)
a(11) = -3 + 25
a(11) = 22

HCF = 13
Let the numbers be 13x and 13y.
Where x and y are co-prime.
∴ LCM = 13 xy
∴ 13 xy = 455

∴ Numbers are 13 × 5 = 65 and 13 × 7 = 91
