Correct Answer :- b

Explanation : Aurangzeb felt that he was superior not only had he become superior to administer the empire in a better way but also to protect and strengthen Islam particularly its Sunni faith. He was a strict follower of the Sunni sect not Shia.

• Second Anglo-Afghan War (1870-80): Lytton made an offer of a favourable treaty to Sher Ali, but the Amir wanted friendship with both his powerful neighbours. 

•  Sher Ali fled in face of the British invasion, and the Treaty of Gandamak (May 1879) was signed with Yakub Khan, the eldest son of Sher Ali. 

For this question, we will use the given table-

The relation of NZ : MA  is given below-

Similarly,

We will apply the same relation to TV : ? as-

Hence, Option (3) is correct.

The logic followed is:

In each next step 1 line segment is deleting from the given letter.

In figure A

The given shape is the letter "E".

In figure B

One line segment get deleted from the right end

Thus we get 

In figure C

Again the one-line segment gets deleted from the right end.

Thus we get 

Similarly,

In figure D

Again one line segment will get deleted from the previous image to obtained figure D.

Thus only one figure is satisfying the pattern.

Hence, the correct answer is "Option 2".

The logic follows here is:

It is given that Rahul has 48% marks in 10th, an age of 28 years, and work experience of 5 years.

It is clearly mentioned in the criteria that 10^th marks should be greater than 50% for job P and greater than 60% for job Q. Rahul got 48% marks in 10^th.

Therefore, Rahul, neither qualifies for job P nor for job Q.

Hence, the correct answer is "Neither P nor Q".

The pattern followed is:

Hence, the correct answer is "PM".

The logic followed is:

The bottom number = sum of the square of all the first three number column-wise 

In column-wise operation:

Column 1:

69 = 7² + 4² + 2² 

69 = 49 + 16 + 4

69 = 69

Column 2:

91 = 32 + 92 + 12 

91 = 9 + 81 + 1

91 = 91

Similarly,

Column 3:

? = 22 + 62 + 52 

? = 4 + 36 + 25

? = 65 

Hence, the correct answer is "65".

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 patterns 13 ± 1, 23 ± 1,  and so on.
• The difference of the numbers could be in the patterns 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. 

The logic is:

the pattern being followed here is:

(Number)² : (Number)³

1. 225 : 3375 → 15² : 15³

2. 49 : 280 → 7² : 7³ = 343 ≠ 280

3. 64 : 512 → 8² : 8³

4. 25 : 125 → 5² : 5³

Hence, ‘49 : 280’ is the odd one out. 

Only daughter of woman’s father is woman herself. So, the woman is person’s mother.

Since ∠1 = ∠2

But BD = CD (given)

AB = AC
∴ the given ∆ is isosceles

Let AB be the light house and the two boats be at C and D

∴ AB = 125 m

tan30° = BC/AB = x/125 = 1/3

=> x = 72.17 m

tan45° = BD/AB = y/125 = 1

=> y = 125 m

∴ The distance between the two boats is = x + y

= 72.17 + 125

= 197.17 m

Let AB be the kite and AC be the level ground
So that BC - AC.
At that point, ∠BAC = 60°and BC = 75m. Let AB = x meters.
Presently AB/BC = coses60° = 2/ √3
=> x/75 = 2/√3 => x = 150/√3 = 150 * √3/3 = 50 √3m.
∴ Length of the string = 50 √3m.

18% of x = 13.50% of y

50% of x = 37.50% of y
Hence, Option D is correct.

The total surface area of a cylinder = 2πrh + 2πr² = 2πr(h + r)

Hence, Option D is correct.

Hence, Option D is correct.

Let AB be the post and AC be its shadow.
Let AB = X m. Then, AC = √3Xm.Let∠ACB = θ.
AB/AC = tanθ => tanθ = X/√3X = 1/√3 = tan30°.
∴ θ = 30°.
Hence, the point of rise is 30°.

Total females = 100% - 52% = 48%
So the answer = (100 – 60)% of 52% + (100 – 70)% of 48% = 35.20%
Hence, Option B is correct.
