Why this answer is correct

Given,

Statement:

Urban areas have expanded rapidly, but public transport has not kept pace. As a result, traffic congestion and air pollution have increased. Experts recommend massive investments in metro lines, electric buses, and last-mile connectivity to address urban mobility challenges.

Conclusions:

I. The lack of adequate public transport contributes to pollution in cities - Follow (Because the statement explicitly mentions that the lack of public transport has resulted in increased air pollution).

II. Improving public transport can reduce urban mobility problems - Follow (Because experts recommend investments in public transport solutions, which implies that improving public transport can mitigate mobility issues).

III. Urban growth is always a negative phenomenon - Does not follow (Because the statement does not suggest that urban growth is inherently negative, but rather highlights the need for better infrastructure to support it).

So, Only conclusions I and II follow.

Hence, the correct answer is "Option 2".

View answer & explanation

Correct answer

Answer: (b)B.

Moderate-salary job with flexibility

Why this answer is correct

Given,

Statement:

Nisha is choosing between two job offers. One offers a high salary but requires frequent travel and overtime. The other offers flexible hours, remote work, and a moderate salary. Nisha values work-life balance and spends weekends with her family. Which job should she take?

Analysis:

Based on the given information, Nisha values work-life balance and spending time with her family. Therefore, a job that aligns with these priorities would be more appropriate for her. The high-salary job involves frequent travel and overtime, which could negatively impact her work-life balance and family time. On the other hand, the moderate-salary job offers flexible hours and remote work, which would allow her to maintain her priorities and spend quality time with her family.

Hence, the correct answer is "Option 2".

Question 8

SSC Combined Higher Secondary Level (CHSL) 2025• General Intelligence• General Intelligence

In a row of 30 students, Ravi is 12th from the left and Priya is 8th from the right. How many students are sitting between Ravi and Priya?

  1. AOption (a)

    8

  2. BOption (b)

    9

  3. COption (c)

    10

  4. DOption (d)

    11

View answer & explanation

Correct answer

Answer: (c)C.

10

Why this answer is correct

The logic followed here is:

Position of Ravi from the left = 12th

Position of Priya from the right = 8th

Total number of students = 30

Position of Priya from the left = Total students - Position of Priya from the right + 1

= 30 - 8 + 1 = 23

Number of students sitting between Ravi and Priya = Position of Priya from the left - Position of Ravi from the left - 1

= 23 - 12 - 1

= 10.

Hence, the correct answer is "Option 3".

Question 9

SSC Combined Higher Secondary Level (CHSL) 2025• General Intelligence• General Intelligence

In a row of 80 students, if Arun is 23rd from the left and there are 18 students between Arun and Bharat, what is Bharat's position from the right end? (Bharat is to the right of Arun)

  1. AOption (a)

    38

  2. BOption (b)

    39

  3. COption (c)

    40

  4. DOption (d)

    41

View answer & explanation

Correct answer

Answer: (b)B.

39

Why this answer is correct

The logic followed here is:

Position of Arun from the left = 23rd

Since there are 18 students between Arun and Bharat, Bharat's position from the left = (23 + 18 + 1) = 42nd

To find Bharat's position from the right, use the formula:

Position of Bharat from the right = Total students - Position of Bharat from the left + 1

= 80 - 42 + 1

= 39

Hence, the correct answer is "Option 2".

Both I and II are strong

Why this answer is correct

Given:

Statement :

Should free healthcare be provided to all citizens regardless of income?

Now,

Arguments :

I. Yes, healthcare is a basic right and should be accessible to all - True (Healthcare is indeed considered a fundamental right by many, and accessibility ensures equity and social welfare).

II. No, it will put excessive financial pressure on the government - True (Providing free healthcare to all citizens can significantly strain government resources and budgets).

So, Both I and II strengthen the statement.

Hence, the correct answer is "Option 3".

Answer: (a)A.

Only I follows

Why this answer is correct

Given:

Statement: Many people are complaining about adulterated milk being sold in the market, causing health issues.

Course of Action:

I. Conduct regular inspections and impose strict penalties on offenders - True (Because this action directly addresses the problem by creating a deterrent and ensuring the quality of milk being sold).

II. Ban the sale of milk in the market for six months - False (Because this is an extreme measure that would create unnecessary difficulties for consumers and traders instead of solving the root cause of the problem).

So, Only I follows.

Hence, the correct answer is "Option 1".

View answer & explanation

Correct answer

Answer: (d)D.

Inform users transparently about the breach and the steps taken to fix it.

Why this answer is correct

Given,

Statement:

An IT company discovers a minor security breach in one of its user databases. No major data has been compromised, but it could become serious if not handled properly. The management must decide how to proceed without causing unnecessary panic among users.

Options:

  1. Hide the issue and hope it doesn’t escalate - False (Because, hiding the issue does not ensure that the breach will not escalate and could compromise the company's reputation if discovered later).
  2. Publicly announce a major crisis to alert all users - False (Because, announcing a major crisis unnecessarily could create panic among users, which is not ideal since the breach is minor).
  3. Quietly patch the vulnerability and release a generic security update - False (Because, while this resolves the issue technically, it does not transparently inform users about the breach, which is important to maintain trust).
  4. Inform users transparently about the breach and the steps taken to fix it - True (Because, this approach ensures transparency, builds trust with users, and demonstrates the company’s responsibility in handling the situation).

Hence, the correct answer is "Option 4".

View answer & explanation

Correct answer

Answer: (a)A.

Seating arrangement change and multiple versions of question paper

Why this answer is correct

Given,

Statement:

A teacher notices that some students copy from each other during tests. 

Now,

  • Seating arrangement change and multiple versions of question paper – It is a preventive, fair, and ethical approach that maintains exam integrity without harming students emotionally or academically.
  • Ignore it as minor – Allows the problem to continue and may encourage more cheating.
  • Publicly shame the students caught – Unethical, damages student morale, and can create fear rather than discipline.
  • Cancel all future tests – Overreaction that disrupts the learning and evaluation process.

So, Option I follows.

Hence, the correct answer is "Option 1".
