Statement:

A surge in dengue cases has been reported in the city due to water stagnation during monsoon.

Courses of Action:

I. Conduct mass fumigation drives and clean stagnant water.

II. Declare a public holiday until the monsoon ends.

Analysis:

I. Conduct mass fumigation drives and clean stagnant water – Follows (Dengue spreads through mosquitoes that breed in stagnant water, so fumigation and cleaning stagnant water directly address the cause of the problem.)

II. Declare a public holiday until the monsoon ends – Does not follow (Declaring a public holiday does not solve the root cause of dengue spread and is not a practical solution.)

Thus, Only Course of Action I follows.

∴ The correct answer is Option (1).

Given: P, M, J, G, ?

The pattern followed here is:

∴ The correct answer is Option (1).

The logic followed here is:

∴ The correct answer is Option (3).

In the given situation,

Therefore Option 3 is the correct answer.

Given word: ESTABLISHMENT

Option 1) TENTS → Can be formed as ESTABLISHMENTS.

Option 2) STATE → Can be formed as ESTABLISHMENT.

Option 3) TABLE → Can be formed as ESTABLISHMENT.

Option 4) BLUNT → Cannot be formed as letter U is not present in ESTABLISHMENT.

Hence, "Option 4" is the correct answer.

In the given situation,

Therefore Option 4 is the correct answer.

CE : XV

Similarly, KG : ?

∴ The correct answer is Option(4).

The logic followed here is:

AC : DB

Similarly, EG : ?

∴ The correct answer is Option (4).

The logic followed here is:

∴ The correct answer is Option (2).

The logic followed here is:

⇒ (3 × 5) + 7 = 22

⇒ (22 × 5) + 7 = 117

⇒ (117 × 5) + 7 = 592

⇒ (592 × 5) + 7 = 2967

∴ The correct answer is Option (2).

The logic followed here is:

⇒ (10 × 5) - 9 = 41

⇒ (41 × 5) - 9 = 196

⇒ (196 × 5) - 9 = 971

⇒ (971 × 5) - 9 = 4846

∴ The correct answer is Option (3).

Given pairs:

1. 12 : 19

2. 25 : 32

3. 41 : 48

4. 13 : 21

Check the pattern:

12 + 7 = 19

25 + 7 = 32

41 + 7 = 48

But,

13 + 7 = 20 ≠ 21

Here the difference is 8 instead of 7.

Hence, 13 : 21 does not follow the pattern.

∴ The correct answer is Option (4)

Given Equation : 12 # 7 ^ 3 $ 10 = ?

Symbol meanings:

! → ÷

→ ×

^ → +

$ → −

Calculation:

12 # 7 ^ 3 $ 10 = ?

After replacing the symbols with their actual signs,

12 × 7 + 3 − 10 = ?

⇒ 84 + 3 − 10

⇒ 87 − 10

⇒ 77

Hence, the correct answer is 77.$

The arrangement of the given words in the order in which they appear in an English dictionary is as shown below:

5. Refrigerator

3. Representation

1. Responsibility

2. Restaurant

4. Revolution

Hence, the correct order is: 5, 3, 1, 2, 4

The arrangement of the given words in the order in which they appear in an English dictionary is as shown below:

1. Rainbow

2. Rather

4. Recent

3. Reason

5. Region

6. Remove

Hence, the correct order is: 1, 2, 4, 3, 5, 6

Here, each letter of the word is shifted 3 positions forward in the English alphabet.

H → K

A → D

R → U

M → P

O → R

N → Q

Y → B

Hence, the logic followed is: Each letter is replaced by the letter that is 3 positions ahead in the alphabet.

Now apply the same logic to BALANCE:

B → E

A → D

L → O

A → D

N → Q

C → F

E → H

Thus, BALANCE → EDODQFH

Hence, the correct answer is EDODQFH.

Observe the pattern:

Each letter of the given word is replaced by the next letter in the English alphabet (+1 shift).

Example from the first word:

A → B

R → S

C → D

H → I

A → B

E → F

O → P

L → M

O → P

G → H

I → J

C → D

A → B

L → M

Hence, the logic followed is: Each letter is replaced by the next letter in the English alphabet.

Now apply the same logic to PSYCHOLOGICAL:

P → Q

S → T

Y → Z

C → D

H → I

O → P

L → M

O → P

G → H

I → J

C → D

A → B

L → M

Thus, PSYCHOLOGICAL → QTZDIPMPHJDBM

Hence, the correct answer is QTZDIPMPHJDBM.

Observe the pattern:

M → N

A → B

T → U

H → I

E → F

M → N

A → B

T → U

I → J

C → D

S → T

Similarly,

G → H

E → F

O → P

G → H

R → S

A → B

P → Q

H → I

Y → Z

Hence, the logic followed is: Each letter is replaced by the next letter in the English alphabet (+1 shift).

Now apply the same logic to CHEMISTRY:

C → D

H → I

E → F

M → N

I → J

S → T

T → U

R → S

Y → Z

Thus, CHEMISTRY → DIFNJTUSZ

Hence, the correct answer is DIFNJTUSZ.

Analysis of Conclusions:

Conclusion I: Surveillance technology has both benefits and risks.

The statement mentions improvement in security (benefit) and privacy concerns (risk). Therefore, this conclusion follows.

Conclusion II: Public oversight and clear policies are needed to balance privacy and security.

The statement clearly says critics demand transparent policies and public oversight. Hence, this conclusion follows.

Conclusion III: Surveillance should be completely banned to protect individual freedom.

The statement only mentions concerns and demand for oversight, not a complete ban. Hence, this conclusion does not follow.

Hence, the correct answer is: Only Conclusions I and II follow.

Situation:

A student has only 3 days left before an exam and half the syllabus is still incomplete.

Analysis of Options:

Watch motivational videos to calm nerves

This may reduce stress, but it does not directly help in completing the syllabus. Hence, it is not the most practical strategy.

Sleep less and cover all topics

Reducing sleep can harm concentration and efficiency, which may negatively affect exam performance.

Focus on high-weightage and familiar topics

This is a practical and effective strategy when time is limited. Prioritizing important and known topics can maximize marks within the available time.

Give up and skip the exam

This is not a reasonable response because the student still has time to prepare.

Hence, the correct answer is Focus on high-weightage and familiar topics.
