Pooja is third to the extreme right end. Vishu is second to the left of Pooja. 
=> Vishu sits at extreme left end.
Vishakha is to the right of Pooja. Rani is third to the right of Ram, who is the immediate neighbour of Vishu.
=> Rani sits at extreme right end, and Ram sits between Vishu and Pooja.
Thus, arrangement:

∴ Pooja is sitting in the middle.
=> Ans - (a)

The pattern followed is that the sum of digits of second number is subtracted from the sum of digits of first number.
Eg: 45 % 11 = (4 + 5) - (1 + 1) = 9 - 2 = 7
and 59 % 34 = (5 + 9) - (3 + 4) = 14 - 7 = 7
Similarly, 55 % 4 = (5 + 5) - (4) = 10 - 4 = 6
=> Ans - (a)

The waste material of a house is called garbage and the waste of an ore is gangue.

Given = D × H : 4 × 8
Alphabets in English alphabetical series are given numbers starting from A = 1 , B = 2 , C = 3 and so on.
Similarly, M = 13 and Q = 17
Thus, M × Q : 13 × 17
=> Ans - (d)

Expression = 9 : 50 : : ?
The pattern followed is = n : 5n + 5
Eg = 9 : 5(9) + 5 = 9 : 50
Similarly, 20(5) + 5 = 100 + 5 = 105 
=> Ans - (d)

Expression = KMNP : ACDF : : PRSU : ?
The pattern followed is :
K (+2 letters) = M (+1 letter) = N (+2 letters) = P
A (+2 letters) = C (+1 letter) = D (+2 letters) = F
P (+2 letters) = R (+1 letter) = S (+2 letters) = U
Similarly, T (+2 letters) = V (+1 letter) = W (+2 letters) = Y
=> Ans - (b)

Expression = 82 : 06 : : 76 : ?
The number on the right is equal to the difference of the digits of the number on the left.
Eg = 8 - 2 = 06
Similarly, 7 - 6 = 01
=> Ans - (b)

The sum of digits of each number:

(a) 5061 = 5 + 0 + 6 + 1 = 12

(b) 4025 = 4 + 0 + 2 + 5 = 11

(c) 7202 = 7 + 2 + 0 + 2 = 11

(d) 6023 = 6 + 0 + 2 + 3 = 11

=> Ans - (a)

Expression = CDGF : HILK : : NORQ : ?

The pattern followed is:

Similarly, for NORQ:

=> Ans - (c)

Weight of the boxes = 30, 20, 60 and 70 kilograms

(a) 180 = 30 + 20 + 60 + 70 = 180

(b) 150 = 20 + 60 + 70 = 150

(c) 120 = 30 + 20 + 70 = 120

(d) 170 = not possible

=> Ans - (d)

Average temperature of a town in the first six days  = 410C

=> Sum of temperatures in 6 days = 6 × 410 = 2460C

Sum of the temperatures of the first five days of the same month = 2010C

∴ Temperature on the sixth day of the month = 2460 - 2010 = 450C

=> Ans - (b)

Expression: 505 & 5 # 4 @ 20 % 5 = ?

≡ 505 ÷ 5 − 4 + 20 × 5

= (550/5​) + (−4) + (20 × 5)

= 101 - 4 + 100 = 197

=> Ans - (b)

Expression: 96 x 12 - 4 + 13 ÷ 21 = ?

≡ 96 ÷ 12 × 4 − 13 + 21

= (8 × 4) + 8

= 32 + 8 = 40

=> Ans - (b)

Expression: 16 P 24 M 8 Q 6 M 2 L 3

≡ 16 + 24 ÷ 8 − 6 ÷ 2 × 3

= 16 + 3 - 9 = 10

=> Ans - (d)

Product and multiplication are synonyms, similarly sum and addition have same meaning.

Expression: 84 @ 12 # 3 $ 24 % 35 = ?

≡ 84 ÷ 12 × 3 + 24 − 35

= (7 × 3) − 11

= 21 − 11 = 10

=> Ans - (c)

In each row, the number in the middle is the arithmetic mean of the other two.

=> 150 + x = 240

=> x = 240 − 150 = 90

=> Ans - (d)

In each row, the number at the leftmost position is obtained by adding the other two.

Eg: 78 + 9 = 87

and 78 + 25 = 103

Similarly, x + 57 = 104

=> x = 104 - 57 = 47

=> Ans - (b)

In the first row, the number at the middle is obtained by taking the product of the other two.

Eg: 7 × 8 = 56

and 11 × 9 = 99

Similarly, 9 × x = 45

=> x = 45/9​ = 5

=> Ans - (c)

In the first column, number at the end is obtained by taking the square of the difference of the other two numbers.

Eg: (17 − 12)² = 5² = 25

and (11 − 13)² = (−2)² = 4

Similarly, (19 − 16)² = 3² = 9

=> Ans - (a)

In the first column, number at the end is obtained by taking the product of the other three.

Eg: 9 × 3 × 3 = 81

and 11 × 4 × 4 = 176

Similarly, 13 × 7 × 5 = 455

=> Ans - (c)
