As a result of Nur Jahan's machinations against Jahangir, Mahabat Khan decided to take action, and so in 1626, he led an army of loyal Rajput soldiers to Punjab. He had also brought the wives and families of many of them, so that, if driven to extremity, they would fight to the last for the lives and honour of themselves and their families. Meanwhile, Jahangir and his retinue were preparing to head to Kabul, and were encamped on the banks of the River Jhelum. Mahabat Khan and his forces attacked the royal encampment, and successfully took the emperor hostage; Nur Jahan, however, managed to escape.

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 Z is good in English, Mathematics, and Science but poor in Social Studies.

Hence, the correct answer is "Z".

The pattern followed is:

Hence, the correct answer is "127".

Alternate Method
The pattern followed is:
3 = 2² - 1
7 = 2³ - 1
15 = 2⁴ - 1
31 = 2⁵ - 1
63 = 2⁶ - 1
127 = 2⁷ - 1
Hence, the correct answer is "127".

Given: 24$3@8#45*5
After replacing the symbols we get:
24 + 3 x 8 - 45 ÷ 5
= 24 + 3 x 8 - 9
= 24 + 24 - 9
= 48 - 9
= 39
Hence, 39 is the correct answer.

The pattern followed here is:

Hence, the correct answer is "L".

1) 8, 4, 6, 1, 5, 3, 7, 2 

2) 7, 8, 3, 4, 5, 2, 6, 1

3) 3, 6, 1, 5, 4, 8, 2, 7

4) 7, 3, 6, 1, 5, 8, 4, 2

'RESIDENT' is a meaningful English word.

Hence, '7, 8, 3, 4, 5, 2, 6, 1' is the correct answer.

From Statement 1:

C = X ≤ D ≥ R

From the statement, the conclusion H < D is not followed because H is absent.

From Statement 2:

R > Z = O > H

From the statement, the conclusion H < D is not followed because D is absent.

From Statement1 and Statement2:

We have, C = X ≤ D ≥ R > Z = O > H

From the statement, H < O = Z < R ≤ D, the conclusion H < D is followed.

Hence option D is correct.

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

Hence, Option B is correct.

The average of the last two numbers

Hence, Option A is correct.

Let the numbers be 23x and 23y where x and y are co-prime.
∴ LCM = 23 xy
As given,
23xy = 23 × 13 × 14
∴ x = 13, y = 14
∴ The larger number = 23y
= 23 × 14 = 322

Hence, Option B is correct.

Let the required number be x.
As given,

10 men = 20 women
Man : Woman = 2 : 1

Hence, Option B is correct.

Pipe Q alone can fill the tank in

Hence, Option D is correct.

Hence, Option C is correct.

Time taken by B = 400 – 80 = 320 seconds

Hence, Option A is correct.

a = 1/ (3-2√2) 

b =  1/ ( 3+2√2) 

∴ ab =  1/(3-2√2) * 1/ (3+2√2) 

=>  1/ (9-8) 

=> 1 

We know; 

(a+b)² = a² + b² + 2ab

And, a²+ b² = (a+b)² - 2ab

=> [ 1/(3-2√2) + 1/(3+2√2) ]² -2*1

=> [3+2√2+3-2√2 / 1]^2 -2 

=> (6)² - 2 

=>  36 - 2
=>  34
