The correct option is B.
When we talk about the Vijayanagara Empire, we all remember the popular and great king, Sri Krishnadevaraya and the capital city of his kingdom, Hampi. Many people do not know about the second capital and summer capital of Vijayanagara Empire, Penukonda. Penukonda means “Big Hill”.

B is the correct option.In Hindu thought, some suffering is self-caused (karma in this life or past life, either intentionally or from ignorance), some caused by evilness of others. The Islamic tenets of brotherhood and equality expose some of the evils of Hinduism.

The 'Garibi Hatao' slogan was targeted more towards the rural poor and aimed at social change and eradication of poverty.

Utility can be measured cardinally according to Marshall, but according to Hicks (ordinal approach) we can rank our preferences so utility is not always measurable cardinally.

The United Nations works on addressing issues like climate change to protect the environment and ensure a sustainable future.

Hence, the applicant meets all the criteria.

A Priest wears cassock (a full-length garment worn by certain Christian clergy, members of church choirs, and others having an office or role in a church.) while Graduate wears gown.

The Logic followed here is:

The third number = The First number × (second number ÷ 2)

In Row 1:- 10, 4, 20

The third number = 10 × (4 ÷ 2)

= 10 × 2 = 20

In Row 2:- 15, 8, 60

The third number = 15 × (8 ÷ 2)

= 15 × 4 = 60

Similarly,

In Row 3:- 25, 8, ?

The third number = 25 × (8 ÷ 2)

? = 25 × 4 = 100

Hence, the correct answer is "100".

Additional Information 

The most common pattern asked in exams are based on:

• It could be the sum of two numbers divided by a constant
• It could be the average of numbers.
• It could be in the form of alphabets, where alphabets are increased by constant or increased by the square of numbers or increased by prime numbers.
• It could be the difference of product of two diametrically opposite numbers.
• It could be the difference in the sum of adjacent numbers.
• The difference of the numbers could be in the pattern 13 ± 1, 23 ± 1,  and so on.
• The difference of the numbers could be in the pattern 12 ± 1, 22 ± 1, and so on.
• Numbers could be 12, 22, 32, and so on or 13, 23, 33, and so on.
• The difference could be prime numbers or the difference could be the square of prime numbers.
• The difference could be in the form of N2 ± N or N3 ± N.
• The difference could be in the form of ×N + N or ×2 + 1, ×2 + 2, ×2 + 3, and so on.
• The difference could be in the form of ×2 ± 1 alternatively.
• Numbers could be ×1, ×2, ×3, and so on. 

From the final arrangement, we get V sits second to the right of S.
Hence, Option B is correct.
References:
Q sits second to the right of P.
Inferences:
From the above reference, we get two different cases:
In case 1, P sits at the corner or in the middle of the side of the table.

References:
R is not an immediate neighbor of P.
R faces inside.
R sits third to the left of W.
Inferences:
From the above references, we get different cases for R, in case 1(a) in which R faces P and in case 1(b) R faces Q.

References:
T sits third to the left of U.
V sits second to the left of U.
Inferences:
So, from this case 1(b) and case 2 will be eliminated as there is no possible place for V in these cases after placing U and T. Hence, we get our final arrangement in which S sits on the immediate left of P and V sits on the immediate right of R.
Final arrangement:

First Number x Second Number = HCF x LCM
Then, 75 x Second Number = 15 x 225
Second Number latex ={ 15 x 225}/75 = 45$
Therefore, other number is 45. 

You can solve this question using the options. Option (a) fits the given situation best as if we take
the distance as 12 km he would have taken 1 hour to go by car and 4 hours to come back walking
—a total of 5 hours as given in the problem.

Let 3889 + 12.952 - x = 3854.002.

Then x = (3889 + 12.952) - 3854.002

= 3901.952 - 3854.002

= 47.95.

Given:

Odd numbers from 1 to 100.

Formula used:

The sum of n of odd number = n²

Where, n = Number of terms

Number of terms = (First terms + Last terms)/2

Average = The sum of all number/(Total number)

Calculation:

The odd numbers between 1 to 100,

1 + 3 + 5 + ..........+ 99 

Number of terms = (First terms + Last terms)/2

⇒ n = (1 + 99)/2

⇒ n = 50

Hence, Option A is correct.

All even numbers between 1 and 50 = 2 to 48

Hence, Option D is correct.

Hence, Option D is correct.

1st term = 2
2nd term = 2 + 3 = 5
3rd term = 5 + 4 = 9
4th term = 9 + 5 = 14
5th term = 14 + 6 = 20
6th term = 20 + 7 = 27

Thus, Missing number is 4th term = 14

These are all defensive games.

According to the information given in the question, we can draw the following diagram.

Thus we can see if a man has to travel to point E from point A  (through these points by the shortest distance), he has to follow a path point A → B → F → E.

Thus travelling from point A, he will pass the first point B.

Hence, the correct answer is "Point B".

Let AB be the observer and CD be the tower.

Draw BE ⊥ CD.

Then, CE = AB = 1.6 m,

BE = AC = 20√3 m.

∴ CD = CE + DE = (1.6 + 20) m = 21.6 m.

Time → A : C = 40 : 90 = 4 : 9
Efficiency → A : C = 9 : 4

Hence, Option D is correct.
