• Through the 18th century, the Mughal Empire gradually fragmented into a number of independent, regional states.
• It can be divided into three overlapping groups:

1. States that were old Mughal provinces like Awadh, Bengal, and Hyderabad. Although extremely powerful and quite independent, the rulers of these states did not break their formal ties with the Mughal emperor.
2. States that had enjoyed considerable independence under the Mughals as watan jagirs. These included several Rajput principalities.
3. States under the control of Marathas, Sikhs and others like the Jats. They all had seized their independence from the Mughals after a long-drawn armed struggle.

Concept:

Greenhouse Effect: The solar energy trapped by the earth atmosphere and radiate it slowly so to cover our earth with a warm blanket. This is the natural process of the greenhouse effect on earth to maintain its temperature and makes the earth perfect for life.

Greenhouse gases are carbon dioxide, other greenhouse gases are methane, water vapour, nitrous oxide, CFCs and ozone. 

Values of radiation absorbed by the greenhouse gases are as follow:

Explanation:

Global Warming

• An increase in the average temperature of the earth surface due to the greenhouse effect is called global warming
• It also refers to the increase in the average temperature of the air and sea at the earth's surface.
• The greenhouse gases combined increased the temperature of planet earth so the correct option is greenhouse gases.

The correct answer is wood.

Concept:

Segregation of Waste: Waste Can be segregated as

• Bio-Degradable Waste: 
  • Waste that can be decomposed by microorganisms. 
  • It includes organic waste, e.g. kitchen waste, vegetables, fruits, flowers, leaves, wood, and paper.​
• Non-Bio Degradable Waste:
  • ​Waste that cannot be decomposed by microorganisms.
  • It includes plastic, rubber, glass, electronic waste, etc. 

Explanation:

Non-Biodegradables can be disposed of by following the 3Rs: 

• Reduce: If the old objects (bags, water bottles, clothes) are in good condition, it's better to keep using them rather than buying new things. 
• Reuse: Jam or pickle jars or plastic bottles can be used again to store small objects like buttons. 
• Recycle: Paper, glass, some plastics, and metals can be recycled. 

Wood is biodegradable, it can be made into compost but cannot be recycled. 

Consumer surplus, also called social surplus and consumer's surplus, in economics, the difference between the price a consumer pays for an item and the price he would be willing to pay rather than do without it.

NASA and Japan’s space agency, JAXA, are planning to launch the world’s first wooden satellite, LignoSat, in 2024. The satellite is designed to reduce space debris and is made of biodegradable magnolia wood, known as Hoonoki in Japanese. The satellite is being developed by scientists at Kyoto University. First tests have been performed in space-simulating laboratories, and wood samples found no signs of damage, decomposition, or mass changes. The initiative aims to make spaceflight operations more sustainable and pave the way for a more sustainable future in orbit.

Given:

x + 1/x = 25

Concept Used:  

If x + 1/x = p then, x – 1/x = √(p² – 4)

Calculation:

It is given that x + 1/x = 25

 We know that if x + 1/x = p then, x – 1/x = √(p² – 4)

⇒ x – 1/x = √(25² – 4)

⇒ x – 1/x = √(625 – 4)

⇒ x – 1/x = √621

The Venn diagram that best represents the relationship between Crockery, Plate, and Bowl is shown below:

Bowl and Plate are name of Crockery items.

Hence, ‘option 3’ is the correct answer.

The logic followed is:
Top number = (sum of the bottom number)²
In fig 1:
225 = (8 + 7)²
225 = 15²
225 = 225
In fig 2:
49 = (3 + 4)²
49 = 7²
49 = 49
Similarly,
121 = (6 + ?)²
√121 = 6 + ?
11 = 6 + ?
? = 11 - 6
? = 5 
Hence, the correct answer is "5".

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 Y and Z pairs of friends are good, both in English and Science

Hence, the correct answer is "Y and Z".

Thus, the code for REMAIN is 8@7$%6.
Hence, option D is correct.

After rearrangement, we get the following arrangement:

So, E is sitting 3rd to the left of D after rearrangement.
Hence, Option C is correct.
Final Arrangement:

Common explanation:
References:
Six person A, B, C, D, E and F sit around a triangular table.
One person sits at each corner of the table facing away from the centre while one person sits at the middle of each edge facing toward the centre.
Inferences:
So, we need to arrange as follows to accommodate the information as stated in the question,

References:
Three persons sit between C and D, who is not facing the centre.
Inferences:
From the above reference, we get two different cases:
Case 1:

Case 2:

References:
F sits third to the left of C.
A sits second to the left of E.
A is not an immediate neighbour of D.
Inferences:
So, from this case 2 will be eliminated as A is not an immediate neighbour of D.
Case 1:

Case 2: (Eliminated)

Hence, Case 1 is the final arrangement.

As cat has Paw similarly Horse has Hoof.

Let the number = x

Hence, Option C is correct.
