The logic followed here is :-  

Given:

Hibiscus – a flower

Tulip – a flower

Apple – a fruit

Daisy – a flower

Hibiscus, Tulip, and Daisy are flowers, while Apple is a fruit.

So, the word that does not belong to the category is: Apple

Hence, the correct answer is Option 2.

The logic followed here is: n³ - n

⇒ 1³ - 1 = 1 - 1 = 0

⇒ 2³ - 2 = 8 - 2 = 6

⇒ 3³ - 3 = 27 - 3 = 24

⇒ 4³ - 4 = 64 - 4 = 60

⇒ 5³ - 5 = 125 - 5 = 120

⇒ 6³ - 6 = 216 - 6 = 210 = ?

Thus, "210" will replace the question mark in the given series.

Hence, the correct option is "Option 3".

The logic followed here is:

thus, "143" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

Given Statements:

No student of Class X failed the science exam this year.

Conclusions:

I. The science exam was very easy - False  (Even if no one failed, it doesn’t prove the exam was easy.

Students might have prepared well, or grading may have been lenient.).

II. All students of Class X passed science - True (If no student failed, it logically means all students passed.).

So, Only Conclusion II follows

Hence, the correct answer is "Option 2".

Given:

Statement: Although recent advancements in quantum computing have significantly improved processing speeds, the stability of quantum states remains a critical barrier to developing large-scale quantum computers for practical applications.

Assumptions:

I. Quantum computing holds the potential for faster data processing than classical computing - True (Because the statement explicitly mentions that advancements in quantum computing have significantly improved processing speeds. This assumes that faster processing is an important potential advantage of quantum computing.)

II. Quantum states are inherently unstable, making large-scale quantum computing unfeasible - False (Because the statement says that the stability of quantum states is a critical barrier, but it does not state that quantum states are inherently unstable or that large-scale quantum computing is completely unfeasible. The issue is presented as a current technological challenge.)

III. Recent advancements in quantum computing have resolved the issue of quantum state stability - False (Because the statement explicitly states that quantum-state stability remains a critical barrier. Therefore, the stability problem has not been resolved by recent advancements.)

So, only Assumption I is implicit.

Hence, the correct answer is "Option 3".

The logic followed here is :-  

Given Word: GARDEN

Letters: G, A, R, D, E, N

Alphabetical order: A, D, E, G, N, R

New letter cluster: A D E G N R

Thus, Fifth from the left → N

Third from the right → G

Here,  Alphabetical order: G, H, I, J, K, L, M, N

Letters between G and N: H, I, J, K, L, M

So, Total letters = 6

Hence, the correct answer is Option 3.

The logic followed here is :-  

Given Word: "ELEVATE"

1^st letter → E

2^nd letter → L

4^th letter → V

5^th letter → A

So, the letters are: E, L, V, A

Thus, Possible meaningful words:

VEAL

VALE

LAVE

All three are valid English words.

Therefore, total meaningful four-letter words = 3

Hence, the correct answer is Option 3.

The logic followed here is:

Logic: The address should match exaxtly.

Given Addrtess:

Rajesh Verma 15B, Sapphire Towers, Jaipur, 302018

Now, checking all the given options:

1. Rajesh Verma 15B, Sapphire Towers, Jaipur, 302018

⇒ Exactly the same.

2. Rajesh Verma 15B, Sapphire Towers, Jaipur, 302019

⇒ PIN code is different (302019 instead of 302018).

3. Rajesh Verma 15B, Sapphire Tower, Jaipur, 302018

⇒ "Tower" is singular instead of "Towers".

4. Rajesh Verma 15B, Sapphire Towers, Jaipur, 302017

⇒ PIN code is different (302017 instead of 302018).

Hence, Option 2 is the correct answer.

The logic followed here is :-

EK :: MS

Similarly, FP : ?

Hence, the correct answer is "Option 3".

The logic followed here is :-

Logic: Swap letters in pairs → (1↔2), (3↔4), (5↔6)

Given:

NUMBER : UNBMRE

NUMBER Positions: 

Rearranged as: 2 1 4 3 6 5 ⇒ U N B M R E

Similarly, GHOSTS : ?

GHOSTS Positions: 

Rearranged as: 2 1 4 3 6 5 ⇒ H G S O S T

Hence, the correct answer is "Option 3".
