The logic followed here is:

Logic: Letters increase by +3 positions and numbers increase by +3 in each step.

Now,

A1@ : D4# : G7$

Letters →

A → D (+3)

D → G (+3)

Numbers →

1 → 4 (+3)

4 → 7 (+3)

Follows the pattern

B2% : E5^ : H8&

Letters →

B → E (+3)

E → H (+3)

Numbers →

2 → 5 (+3)

5 → 8 (+3)

Follows the pattern

C3* : F6( : I9)

Letters →

C → F (+3)

F → I (+3)

Numbers →

3 → 6 (+3)

6 → 9 (+3)

Follows the pattern

D4_ : G8@ : K13$

Letters →

D → G (+3)

G → K (+4) Should be J if +3)

Numbers →

4 → 8 (+4)  (Should be +3)

8 → 13 (+5) 

Does NOT follow the pattern

So, the odd group is D4_ : G8@ : K13$.

Hence, the correct option is "Option 4".$

Given: A said to B: "The woman I met yesterday at the park was the only daughter of the father of your brother."

 

So, The woman A met = B’s sister.

Hence, the correct answer is "Option 1".

Given: A man says, "My son's mother is the only child of your father."

 

So, the man is the husband of that person.

Hence, the correct answer is "Option 2".

Given: Introducing a man, Shruti said, "He is the husband of the granddaughter of the only son of my grandfather."

 

So, The man is Shruti’s daughter's husband or son-in-law.

Hence, the correct answer is "Option 1".

BODMAS Table: 

Given equation: 6 + 3 − 2 × 1 = ?

Now, if ‘+’ = ×, ‘−’ = +, and ‘×’ = ÷, then:

⇒ 6 × 3 + 2 ÷ 1 = ?

⇒ 18 + 2 ÷ 1 = ?

⇒ 18 + 2 = 20

Hence, the correct answer is "Option 1."

The logic followed here is:

So, 'KLV' will replace the question mark in the given series.

Hence, the correct answer is "Option 2".

The logic followed here is:

So, 'RIB' will replace the question mark in the given series.

Hence, the correct answer is "Option 4".

BODMAS Table: 

Given:

'÷' means '+'

'-' means '×'

'+' means '-'

'×' means '÷'

Given equation:

42 × 28 - 30 ÷ 48 + 45 = ?

Now replace the signs accordingly:

⇒ 42 ÷ 28 × 30 + 48 - 45

Now solve step by step:

⇒ 42 ÷ 28 = 1.5

⇒ 1.5 × 30 = 45

⇒ 45 + 48 - 45

⇒ 93 - 45

⇒ 48

Hence, the correct answer is "Option 4".

The logic followed here is:

thus, "98" will replace the question mark in the given series.

Hence, the correct option is "Option 2".

Given:

Statement:

The rapid advancement of automation and artificial intelligence could lead to significant job displacement, but it also presents an opportunity to create new jobs in emerging industries.

Assumptions:

I. Automation and AI could cause job losses in some sectors – True (The statement clearly mentions “job displacement,” which assumes that automation and AI may cause job losses).

II. New industries will emerge as a result of automation and AI – True (The statement says there is an opportunity to create new jobs in emerging industries, which assumes new industries will develop).

III. The displacement caused by automation is temporary and will be reversed by new industries – False (The statement does not assume that job losses will be completely reversed or that the displacement is temporary; it only mentions an opportunity for new jobs).

So, Only assumptions I and II are implicit.

Hence, the correct answer is "Option 1".
