The logic follows here. 

Logic: The pattern is based on adding consecutive perfect squares 1² , 2², 3², 4², 5²) to the preceding number

• 5 + 1² = 5 + 1 = 6
• 6 + 2² = 6 + 4 = 10
• 10 + 3² = 10 + 9 = 19
• 19 + 4² = 19 + 16 = 35
• 35 + 5² = 35 + 25 = 60

Hence, the correct answer is "Option 1."

The logic followed here is:

QX 18 → SS 4:

EL 10 → GG −4:

Similarly, for IJ 5 → KE −9

Thus, IJ 5 is related to KE −9.

Hence, the correct answer is 'Option 4'.

Given number: 36857219

When the digits are arranged in ascending order from left to right, the new sequence is:

Left  12356789  Right 

The second digit from the left in the new number is 2. 

The third digit from the right in the new number is 7 

So, Sum of these two number 2 + 7 = 9.

The correct answer is 'Option 3'.

The logic followed here is:

Therefore, the term that replaces the question mark is ATX.

Hence, the correct answer is option 3

The pattern followed here is,

• The pattern for letters is: Previous letter + 9 = Next letter.
• The pattern for numbers is: Previous number − 5 = Next number.

By combining both patterns, the missing term is B 25.

Hence, the correct answer is option 2

Given:  (Left) K D D U R V U D E C Q D V A D R D G D E D Z D J (Right)

The logic to be followed here is to identify 'D's that satisfy the specific condition mentioned in the question.

Required Condition: Vowel → D → Consonant

Given:  (Left) K D D U R V U D E C Q D V A D R D G D E D Z D J (Right)

There are a total of two such 'D's in the series that satisfy the given conditions: A D R, E D Z

Hence, the correct answer is "Option 1."

Preparing the family tree using the following symbols,

Given : ‘S – D + F ÷ H x K’

The family tree can be drawn using the given information,

Here, S is brother of H and H is wife of K so, we can see that S is wife brother’s  of K.

Hence, the correct answer is "Option 3".

The logic followed here is:

Total number of students in the row = 22

Position of Sunil from the left end = 17^th

Deepak is 3^rd to the right of Sunil.

Position of Deepak from the left end = Position of Sunil from the left end + 3

= 17 + 3

= 20^th

Position of Deepak from the right end = (Total number of students − Position of Deepak from the left end) + 1

= (22 − 20) + 1

= 2 + 1

= 3^rd

Hence, the correct answer is 'Option 1'.

The logic followed here is.

Logic: The difference between the positional values of consecutive letters in each cluster is −1 and −3 based on the English alphabetical order.

For QPM

For BAX

For TTP

For SRO

The pattern observed in QPM, BAX, and SRO is the same. However, TTP follows a different pattern 

Hence, the correct answer is option 3

The logic followed here is.

‘BRAK’ is coded as '4938.'

'ARCK' is coded as '2849.'

The code for ‘C’ in the given code language is 2.

Hence, the correct answer is "Option 3".
