From the given information;

Pankaj is middle of Prakash and Sabnam.

There are 9 people between Prakash and Sabnam.

So, Pankaj is 14th from the front.

Hence, "14th" is the correct answer.

The logic follows here is:-

Square root of each number gives a prime number, except 9.

Let's check each option:-

1) 121 = (11)² . Here 11 is prime number.

2) 81 = (9)2 . Here 9 is not prime number.

3) 169 = (13)2 . Here 13 is prime number.

4) 49 = (7)2 . Here 7 is prime number.

Hence, '81' is odd number among given alternatives.

Let’s check each option:

1) 234165 → ULYOAT

2) 123654 → OULATY

3) 315246 → LOTUYA

4) 364125 → LAYOUT

Hence, ‘364125’ represents a meaningful word ‘LAYOUT’.

Given: 3, 11, 27, 59, ?

The logic followed here is: 

Hence, 123 is the correct answer.

Alternate Method

→ (3 × 2) + 5  = 6 + 5 = 11;

→ (11 × 2) + 5 = 22 + 5 =  27;

→ (27× 2) + 5 = 54 + 5 = 59;

→ (59 × 2) + 5 = 118 + 5 = 123;

The logic followed here is :-

First letter if added +2, next letter in subtracted -2 and repeated for next letters in given word.

‘VENDOR’ is written as ‘TMFLGT’.

Similarly,

‘CUSTOM’ will be written as :

Hence, the correct answer is "OMVQWA".

Hence there are "24" triangles in the figure.

First let's count the sections of the given triangle and then add them, then that is the number of triangles.

Lines originating from the top vertex are dividing the triangle into 4 parts. And naming the parts as 1, 2, 3, and 4. (Upper and bottom figure)

Then adding these parts separately we get,

Number of triangles (Upper)= 1 + 2 + 3 + 4 = 10.

Number of triangles (Upper and bottom) = 2 × 10 = 20.

Number of triangles = 4

Thus, total number of triangles = 20 + 4 = 24.

As Goggles, spectacles and Bifocals are worn by human beings but Optical reader is not worn , It is a device found within most computer scanners that captures visual information and translates the image into digital information the computer is capable of understanding and displaying. 

Hence, option 4 is the correct answer.

Here all the polygon are of odd number of sides except hexagone.

Hendecagon is a polygon of 11 sides, Heptagon is a polygon of 7 sides and Pentagon is a polygon of 5 sides.

Only Hexagon is an odd one here as it has even number of sides i.e. 6 sides.

Hence, option 2 is the correct answer.

Symbol representation :

The family tree diagram is shown below - 

Hence, 'brother-in-law' is the correct answer.

The logic followed here is :-

1. Convert each letters  to its corresponding alphabetical position.

2.  Add 1 to each numerical value and convert the resulting numbers back to letters.

3. Arrange the letters obtained in the previous step in decreasing order of their numerical values.

IVORY : ZWSPJ

Similarly,

CREAM : ?

Hence, the correct answer is "SNFDB".

Hence, the correct answer is ‘Intestine’.

According to given figure:

The figure will appear when it is opened as follows:

Hence, "Option - (3)" is the correct answer.

The pattern followed here is:

Logic: Second number - First number = 89

1) 139 : 228

⇒ 228 - 139 = 89

And,

2) 122 : 211

⇒ 211 - 122 = 89

Similarly,

3) 2 : ?

⇒ X - 2 = 89

⇒ X = 89 + 2

⇒ X = 91

Hence, the correct answer is "91".

The logic followed here is:

(First number × 3) - (Second number × 4) = Third number

First row - 67, 25, 101 → (67 × 3) - (25 × 4) = 201 - 100 = 101

Second row - 55, 17, 97 → (55 × 3) - (17 × 4) = 165 - 68 = 97

Similarly,

Third row - 45, 19, ? → (45 × 3) - (19 × 4) = 135 - 76 = 59

Hence, option 4) is the correct answer.

Important Points

•  NOT Related means "We have to find a pair that is different from the given pair."

• The logic followed here is: Second number = First number × (First number ÷ 2)
• Given: 4 : 8 ⇒ 4 × (4 ÷ 2) = 4 × 2 = 8

1. 8 : 32 ⇒ 8 × (8 ÷ 2) = 8 × 4 = 32
2. 2 : 2 ⇒ 2 × (2 ÷ 2) = 2 × 1 = 2
3. 3 : 9 ⇒ 3 × (3 ÷ 2) = 3 × 1.5 = 4.5 ≠ 9
4. 6 : 18 ⇒ 6 × (6 ÷ 2) = 6 × 3 = 18

Hence, "option 3" is the correct answer.
