Question 1 · Quantitative Aptitude and Data Interpretation (QA & DI) · 2024 MCQ

FS food stall sells only chicken biryani. If FS xes a selling price of Rs. 160 per plate, 300 plates of biriyani are sold. For each increase in the selling price by Rs. 10 per plate, 10 fewer plates are sold. Similarly, for each decrease in the selling price by Rs. 10 per plate, 10 more plates are sold. FS incurs a cost of Rs. 120 per plate of biriyani, and has decided that the selling price will never be less than the cost price. Moreover, due to capacity constraints, more than 400 plates cannot be produced in a day.
If the selling price on any given day is the same for all the plates and can only be a multiple of Rs. 10, then what is the maximum pro t that FS can achieve in a day?

A.
Rs. 25,300
B.
Rs. 28,900
C.
Rs. 41,400
D.
Rs. 52,900
E.
None of the remaining options is correct.

Correct Answer:

Step-by-Step Solution

Key idea: This is a revenue optimization problem with a linear demand curve and discrete constraints. We need to maximize Profit = (Selling Price - Cost Price) * Quantity Sold.

Step 1: Define the demand function.

Base case: Price $P_{0} = 160$ , Quantity $Q_{0} = 300$ .

Change: For every Rs. 10 increase in P, Q decreases by 10.

Let $n$ be the number of Rs. 10 increases.

$P = 160 + 10 n$ .

$Q = 300 - 10 n$ .

Constraints:

$P \geq Cost Price = 120$ .
$Q \leq 400$ (Capacity).
$P$ is a multiple of 10. (Satisfied by formula).
$Q \geq 0$ .

Step 2: Formulate Profit function.

$Profit Z (n) = (P - 120) \times Q$

$Z (n) = (160 + 10 n - 120) \times (300 - 10 n)$

$Z (n) = (40 + 10 n) (300 - 10 n)$

Factor out 10:

$Z (n) = 10 (4 + n) \times 10 (30 - n)$

$Z (n) = 100 (4 + n) (30 - n)$

Step 3: Maximize the quadratic function.

Let $f (n) = (4 + n) (30 - n)$ .

Roots are at $n = - 4$ and $n = 30$ .

The vertex (maximum) of a parabola $a x^{2} + b x + c$ is at the midpoint of roots.

$n_{o pt} = \frac{- 4 + 30}{2} = \frac{26}{2} = 13$ .

Check if $n = 13$ is valid.

$P = 160 + 130 = 290$ . ( $\geq 120$ , OK).

$Q = 300 - 130 = 170$ . ( $\leq 400$ , OK).

Step 4: Calculate Max Profit.

$Z (13) = 100 (4 + 13) (30 - 13)$

$Z (13) = 100 (17) (17)$

$1 7^{2} = 289$ .

$Z (13) = 100 \times 289 = 28, 900$ .

Wait, let me double check the capacity constraint.

"More than 400 plates cannot be produced".

Our Q is 170, which is well within 400.

Is it possible to decrease price?

If $n$ is negative.

Let $m = - n$ (decreases).

$P = 160 - 10 m$ .

$Q = 300 + 10 m$ .

Constraint $Q \leq 400 \Rightarrow 300 + 10 m \leq 400 \Rightarrow 10 m \leq 100 \Rightarrow m \leq 10$ .

Profit $Z (m) = (160 - 10 m - 120) (300 + 10 m) = (40 - 10 m) (300 + 10 m)$ .

$Z (m) = 100 (4 - m) (30 + m)$ .

Roots at $m = 4, m = - 30$ .

Vertex at $m = \frac{4 - 30}{2} = - 13$ .

Since parabola opens downward, max is at vertex. But domain is $m \in [0, 10]$ .

Vertex -13 is outside. Function decreases as we move away from -13?

Actually, vertex is at -13. For $m > - 13$ , the function is decreasing?

Let's check derivative or values.

$f (m) = (4 - m) (30 + m) = 120 + 4 m - 30 m - m^{2} = 120 - 26 m - m^{2}$ .

This is decreasing for all $m \geq 0$ .

So max profit in this region is at $m = 0$ (no change).

$Z (0) = 100 (4) (30) = 12, 000$ .

Comparing regions:

Increase price ( $n > 0$ ): Max 28,900 at $n = 13$ .

Decrease price ( $m > 0$ ): Max 12,000 at $m = 0$ .

Global Max is 28,900.

Let me re-read the options.

A: 25,300

B: 28,900

C: 41,400

D: 52,900

My calculation gives 28,900. This matches Option B.

Wait, did I miss something?

"FS incurs a cost of Rs. 120 per plate".

"Selling price ... multiple of Rs. 10".

Let's re-calculate $17 \times 17$ .

$10 \times 17 = 170$ .

$7 \times 17 = 119$ .

$170 + 119 = 289$ .

$289 \times 100 = 28, 900$ .

Why is Option C 41,400?

Maybe I made a mistake in the demand slope?

"For each increase ... by 10 ... 10 fewer". Slope is -1.

$Q = 300 - (P - 160)$ .

$Q = 460 - P$ .

Profit $= (P - 120) (460 - P)$ .

Vertex at $P = \frac{120 + 460}{2} = \frac{580}{2} = 290$ .

$Q = 460 - 290 = 170$ .

Profit $= (290 - 120) (170) = 170 \times 170 = 28, 900$ .

Calculation is robust.

Let's check if capacity constraint binds in the other direction?

If we decrease price, Q increases.

Max Q is 400.

$400 = 460 - P \Rightarrow P = 60$ .

But $P \geq 120$ .

So min P is 120.

At $P = 120$ , $Q = 460 - 120 = 340$ .

Profit $= (120 - 120) \times 340 = 0$ .

So the range of P is $[120, 460]$ .

Vertex 290 is in range.

Answer is 28,900.

Option B is 28,900.

Why did I write C in the header? I must correct it.

Answer: Option B.

Question 2 · Quantitative Aptitude and Data Interpretation (QA & DI) · 2025 MCQ

Arun selected an integer $x$ between 2 and 40, both inclusive. He noticed that the greatest common divisor of the selected integer $x$ and any other integer between 2 and 40, both inclusive, is 1.

How many different choices for such an $x$ are possible?

A.
4
B.
8
C.
1
D.
12
E.
0

Correct Answer:

Step-by-Step Solution

Key idea: This is a Coprimality in a Range question. We are looking for an integer $x$ such that $g cd (x, y) = 1$ for every other integer $y$ in the range $[2, 40]$ .

Step 1: Analyze the condition.

The condition states that $x$ must be coprime to every other number in the set ${2, 3, \dots, 40}$ .

Let $S = {2, 3, \dots, 40}$ . We need $x \in S$ such that $\forall y \in S, y \neq = x ⟹ g cd (x, y) = 1$ .

Step 2: Test small primes.

If $x$ is a prime number $p$ , does it satisfy the condition?

Consider $x = 2$ . Is $g cd (2, y) = 1$ for all $y \neq = 2$ ? No, because $g cd (2, 4) = 2$ . In fact, any even number $y$ will share a factor of 2 with $x = 2$ . So $x = 2$ fails.

Consider $x = 3$ . Is $g cd (3, y) = 1$ for all $y \neq = 3$ ? No, because $g cd (3, 6) = 3$ . Any multiple of 3 in the range will fail.

Generally, if $x$ has any prime factor $p$ , then any multiple of $p$ in the range (other than $x$ itself) will have a GCD $> 1$ with $x$ .

Step 3: Identify the constraint on prime factors.

For $x$ to be coprime to all other numbers in the range, $x$ cannot share any prime factor with any other number in the range.

This implies that no multiple of any prime factor of $x$ can exist in the range $[2, 40]$ other than $x$ itself.

Let's look at the smallest prime, 2. The multiples of 2 in the range are $2, 4, 6, \dots, 40$ .

If $x$ is even, it shares the factor 2 with all other even numbers. Since there are many even numbers, $x$ cannot be even (unless the range was very small, e.g., only ${2, 3}$ ). Here, if $x = 2$ , it fails against 4. If $x = 4$ , it fails against 2.

Let's look at prime $p$ . If $x$ is a multiple of $p$ , then $x$ shares factor $p$ with $2 p, 3 p, \dots$ as long as they are in the range.

For $x$ to work, there must be NO other multiple of any of its prime factors in the range.

Consider $x = 1$ . But the range is $2$ to $40$ . So $1$ is not an option.

Let's check if any number works.

If $x > 1$ , let $p$ be the smallest prime factor of $x$ .

Then $p \leq x$ .

Also $2 p$ is a multiple of $p$ .

If $2 p \leq 40$ and $2 p \neq = x$ , then $g cd (x, 2 p) \geq p > 1$ , so $x$ fails.

Case A: $x$ is prime.

If $x = p$ , then $2 p$ is in the range if $2 p \leq 40 ⟹ p \leq 20$ .

If $p \leq 20$ , then $2 p$ is in the range $[2, 40]$ and $2 p \neq = p$ . Thus $g cd (p, 2 p) = p > 1$ . So any prime $p \leq 20$ fails.

Primes in $(20, 40]$ are: 23, 29, 31, 37.

Let's test $x = 23$ .

Multiples of 23 in range: 23, 46 (out of range).

So the only multiple of 23 in the range is 23 itself.

Does 23 share any other factors? No, it's prime.

So $g cd (23, y)$ for any $y \neq = 23$ ?

If $y$ is not a multiple of 23, $g cd (23, y) = 1$ because 23 is prime.

Since no other multiple of 23 exists in the range, $g cd (23, y) = 1$ for all $y \in [2, 40], y \neq = 23$ .

So 23 is a valid choice.

Similarly for 29: $2 \times 29 = 58 > 40$ . Valid.

Similarly for 31: $2 \times 31 = 62 > 40$ . Valid.

Similarly for 37: $2 \times 37 = 74 > 40$ . Valid.

Are there any composite numbers?

If $x$ is composite, let $p$ be its smallest prime factor. $x \geq p^{2}$ .

We need no other multiple of $p$ in the range.

This requires $2 p > 40 ⟹ p > 20$ .

If smallest prime factor $p > 20$ , then $x \geq p^{2} > 400$ , which is outside the range $[2, 40]$ .

So no composite number works.

What about primes $p \leq 20$ ? We already showed they fail because $2 p$ is in the range.

So the valid values for $x$ are the primes $p$ such that $2 p > 40$ , i.e., $p > 20$ .

Primes in $[2, 40]$ greater than 20 are: 23, 29, 31, 37.

Count = 4.

Wait, let me re-read carefully. "GCD of selected integer x and ANY OTHER integer... is 1".

My logic for 23: $g cd (23, y) = 1$ for all $y \neq = 23$ . Correct.

Let's double check if I missed any.

Is it possible for a non-prime to work?

If $x$ is not prime, it has a prime factor $p \leq x \leq 40 < 7$ .

So $p \in {2, 3, 5}$ .

If $p = 2$ , $2 p = 4 \leq 40$ . Fail.

If $p = 3$ , $2 p = 6 \leq 40$ . Fail.

If $p = 5$ , $2 p = 10 \leq 40$ . Fail.

So no composite works.

So only primes $p$ where $2 p > 40$ work.

Primes: 23, 29, 31, 37.

Total count = 4.

Answer: 4.

Question 3 · Quantitative Aptitude and Data Interpretation (QA & DI) · 2026 MCQ

Common Description:

Light Chemicals is an industrial paint supplier with presence in three locations: Mumbai, Hyderabad and Bengaluru. The sunburst chart below shows the distribution of the number of employees of different departments of Light Chemicals. There are four departments: Finance, IT, HR and Sales. The employees are deployed in four ranks: junior, mid, senior and executive. The chart shows four levels: location, department, rank and gender(M: male, F: female). At every level, the number of employees at any location/department/rank/gender are proportional to the corresponding area of the region represented in the chart.

Due to some issues with the software, the data on junior female employees have gone missing. Notice that there are junior female employees in Mumbai HR, Sales and IT departments, Hyderabad HR department, and Bengaluru IT and Finance departments: the corresponding missing numbers are marked u, v, w, x, y and z in the diagram, respectively.

It is also known that:

a) Light Chemicals has a total of 210 junior employees.

b) Light Chemicals has a total of 146 employees in the IT department.

c) Light Chemicals has a total of 77 employees in the Hyderabad office.

d) In the Mumbai office, the number of junior female employees is 55.

Based on the given information and the sunburst chart, which of the following statements CANNOT BE TRUE?

A.
In the Hyderabad office, the number of senior employees is more than the number of junior employees.
B.
All three offices put together, the number of Sales employees is less than the number of Finance employees.
C.
In the Bengaluru office, the number of Finance employees is more than the number of IT employees.
D.
Number of female junior employees at Finance and IT departments in the Bengaluru office are equal.
E.
In the Mumbai office, the number of junior employees is more than the number of mid-level employees.

Correct Answer:

Step-by-Step Solution

Key idea: This is a logical deduction question with missing segments, recognizable because it asks which statement CANNOT be true based on partial data and sum constraints.

Step 1: Reuse the equations derived from the common data.

Total junior = 210 => u + v + w + x + y + z = 96.

Total IT = 146 => w + y = 24.

Total Hyderabad = 77 => x = 12.

Mumbai junior female = 55 => w + v + u = 55.

Step 2: Simplify the system. From the first and fourth equations, (u + v + w) + x + y + z = 96 => 55 + 12 + y + z = 96 => y + z = 29.

Step 3: Analyze the options for logical impossibility.

Option D states that the number of female junior employees at Finance (z) and IT (y) departments in Bengaluru are equal.

Step 4: If y = z, then y + z = 2y = 29. This implies y = 14.5.

Step 5: Since the number of employees must be an integer, y and z cannot be equal. Therefore, Option D is mathematically impossible and CANNOT be true.

Answer: Number of female junior employees at Finance and IT departments in the Bengaluru office are equal.

Question 4 · Verbal Ability and Logical Reasoning (VALR) · 2022 MCQ

Carefully read the following statement: When I ask people to name three recently implemented technologies that most impact our world today, they usually propose the computers, the Internet and the laser. All three were unplanned,___________, and_____________ upon their discovery and remained__________ well after their initial use.

Which of the following options will BEST ll up the above blanks meaningfully?

A.
Unpredicted, Unappreciated, Unappreciated
B.
Amazing, Shocking, Shocking
C.
Surprising, Ful lling, Unful lling
D.
Astonishing, Amazing, Amazing
E.
Astonishing, Superb, Superb

Correct Answer:

Step-by-Step Solution

Key idea: This is a contextual fill-in-the-blanks question relying on parallel structure and semantic consistency. The clues "unplanned" and the historical context of technological discovery dictate a specific tone of unexpectedness and initial lack of understanding.

Step 1: Analyze the first blank. The word "unplanned" establishes a theme of lacking foresight. "Unpredicted" is the exact semantic parallel to "unplanned". Words like "amazing" or "astonishing" describe a subjective reaction, not the objective lack of planning.

Step 2: Analyze the second and third blanks. The sentence describes the trajectory of these technologies from discovery to initial use. If they were unplanned and unpredicted, it follows they were not fully understood or valued at first. "Unappreciated" fits both blanks, indicating a continuous state of being undervalued or misunderstood.

Step 3: Evaluate the options. Option A provides "Unpredicted, Unappreciated, Unappreciated", which perfectly maintains the parallel structure and the logical narrative of unforeseen and initially misunderstood technologies.

Answer: A

Question 5 · Verbal Ability and Logical Reasoning (VALR) · 2022 MCQ

Arrange the following sentences in a LOGICAL sequence:

But when it comes to companies that lack computer programmers, the government is far more sympathetic.
As a result, limited access to foreign talent is a common gripe of tech founders and venture capitalists.
And, demand for the latter has soared among British startups.
This is less inconsistent than it may seem.
An HGV driver takes between six and ten weeks to train; a competent coder several years.

A.
3,4,2,1,5
B.
1,4,5,3,2
C.
3,5,1,2,4
D.
1,2,5,3,4
E.
3,5,4,2,1

Correct Answer:

Step-by-Step Solution

Key idea: This is a contrast-and-explanation sequencing question that tests semantic coherence over superficial transition words.

Step 1: Sentence 1 must be the opener among the choices. It begins with "But", implying a contrast with an unstated prior context (e.g., government strictness on another group). It states the government is "far more sympathetic" to companies lacking computer programmers.

Step 2: Sentence 4 directly addresses this apparent contradiction or surprising fact: "This is less inconsistent than it may seem."

Step 3: Sentence 5 provides the logical explanation for this consistency: "An HGV driver takes between six and ten weeks to train; a competent coder several years." (Local training is fast for one, slow for the other, justifying different government approaches).

Step 4: Sentence 3 builds on the coder point using a pronoun reference: "And, demand for the latter [competent coders] has soared among British startups."

Step 5: Sentence 2 provides the concluding consequence of this high demand and long training time: "As a result, limited access to foreign talent is a common gripe..." (Because they take years to train and demand is soaring, they rely on foreign talent, making any limitation a gripe).

Sequence: 1 -> 4 -> 5 -> 3 -> 2.

Answer: B

Question 6 · Verbal Ability and Logical Reasoning (VALR) MCQ

The committee's final report was heavily criticized for being overly _____, failing to address the core systemic issues and instead focusing excessively on minor, irrelevant details.

A.
pedantic
B.
pragmatic
C.
succinct
D.
profound

Correct Answer:

Step-by-Step Solution

Key idea: This is a sentence completion question testing vocabulary in context, specifically focusing on precise semantic fit and tonal consistency.

Step 1: Analyze the context clues. The report is "heavily criticized" for "failing to address core systemic issues" and "focusing excessively on minor, irrelevant details."

Step 2: Determine the required meaning for the blank. The word must describe someone or something that is overly concerned with minor details or formalisms, to the detriment of the bigger picture.

Step 3: Evaluate Option A. "Pedantic" means overly concerned with minute details or formalisms, especially in a tedious way. This fits perfectly.

Step 4: Evaluate Option B. "Pragmatic" means dealing with things sensibly and realistically. This is a positive trait and contradicts the criticism.

Step 5: Evaluate Option C. "Succinct" means briefly and clearly expressed. This contradicts "focusing excessively on minor details."

Step 6: Evaluate Option D. "Profound" means having deep insight. This contradicts "failing to address core systemic issues."

Step 7: Select the best fit. Option A is the only word that matches the negative tone and the specific criticism of focusing on minor details.

Answer: Option A.

Question 7 · Decision Making (DM) · 2022 MCQ

Common Description:

Read the following scenario and answer the THREE questions that follow.

Comprehension: Future Leaders is one of the most prestigious private schools in a small town, next to an industrial hub. Most of its students come from a uent families, but there are some who belong to middle-income and lower-middle-income families as well. The school charges an annual fee of ₹2 lakhs, inclusive of all charges, payable at the beginning of the academic year. Roughly 20% of the fees collected goes into paying the salaries of the teachers, another 30% for the upkeep of the school, and roughly 20% for miscellaneous expenses in running day-to-day businesses like supply, cleaning etc. The remaining goes into an exigency corpus.

This year, like the rest of the country, the town has been hit by the coronavirus pandemic. The classes have been shifted online. The local authorities have mandated that all schools have to reduce their fees by 20%.

Further, parents should be given extended time to pay the fees if they are in nancial distress. Six months into the academic year, only 40% of the parents have paid even the reduced annual fees.

The board of trustees of the school is concerned about the current nancial situation and has called Biswas for a meeting. The trustees have thought of the following actions, as listed below, to improve the school nances immediately: P. Appeal to the local industrialists to donate to the school Q. Withhold 20% of teachers' salary till the situation improves R. Ask parents to pay up within a week or show a proof of nancial distress S. Stop online classes for a week to signal the desperate nancial crunch T. Start an extra section in every class and offer admission to whoever is willing to pay fees Biswas is tasked to nd the most feasible way of alleviating the nancial crunch immediately.

Which of the following combinations of the above-listed actions, in a DECREASING order of preference, will BEST help Biswas in achieving his goal?

A.
PRSQT
B.
TSRPQ
C.
QRSPT
D.
PSTRQ
E.
RSQTP

Correct Answer:

Step-by-Step Solution

Key idea: This is a "priority ranking" decision-making question based on the time horizon of the solution. The keyword is "IMMEDIATELY". We must rank the actions by how fast and feasibly they can alleviate the financial crunch.

Step 1: Evaluate each action for immediacy and feasibility.

Step 2: Action R (Ask parents to pay or show proof) is the most direct, immediate, and feasible way to unlock pending revenue from those who can afford it. It is the highest priority.

Step 3: Action S (Stop online classes for a week) provides immediate relief by cutting operational costs (electricity, misc) and signals the severity of the crunch to parents without directly attacking stakeholders. It is the second highest.

Step 4: Action Q (Withhold 20% salary) provides immediate cash flow relief but is highly toxic to teacher morale and retention. It is a severe internal measure, ranking below S.

Step 5: Action T (Start extra section) requires time for marketing, admissions, and setup. It is a medium-term solution, not immediate.

Step 6: Action P (Appeal to industrialists) is uncertain, takes time to organize, and relies on external charity. It is the least feasible for immediate relief.

Step 7: Order the actions in decreasing preference: R, S, Q, T, P.

Answer: E

Question 8 · Decision Making (DM) · 2024 MCQ

Common Description: Raman had been working tirelessly as a Project Manager in the IT department of Flying Groceries, a renowned app-based supply chain company, for the past three years. Having graduated from a top-tier engineering college, he dived straight into the corporate world, managing projects with great zeal that inspired his seniors.
At the end of his rst year with Flying Groceries, impressed with his hard work, Raman’s boss, Suraj, the founder-CEO of Flying Groceries, fast-tracked his promotion and made him Delivery Manager responsible for multiple projects of a vertical. Suraj also promised Raman the position of Chief Operation O cer in the fth year of his tenure.
In search of a greater career trajectory, Raman pursued entrance exams for business schools. His efforts bore fruits as he secured a place in the country’s best business school, known for a strong alumni base, stellar placement records and demanding academic requirements.
Raman was delighted; he had three months to join the business school. Flying Groceries demanded that any employee who wished to leave the organization should give at least a month’s notice. Raman decided to continue working and enriching his work experience, which will be bene cial when applying to companies after graduating from the business school. Therefore, he decided not to share the news of the offer with anyone else for the time being. Flying Groceries was planning to implement a much-needed update to enhance the functionality and user experience of their app. According to Suraj, the update was expected to take at least six months to complete. Suraj wanted Raman to lead this project because his leadership was critical for the project’s success. However, Raman knew that he would be there only for three months; he was not sure whether he should accept the project.
Which of the following information, if true, will BEST assist Raman in accepting the role of leading the project?

A.
During his time with Flying Groceries, Raman nished some projects ahead of schedule.
B.
Raman could requisition more human resources to his team for the next three months.
C.
Suraj might advise against the update if he got to know that Raman was leaving soon.
D.
The last two projects Raman led were successfully completed by his subordinates during his exams.
E.
Raman had previously taken many projects home, and the business school would have no classes during the weekends.

Correct Answer:

Step-by-Step Solution

Key idea: This is a "project continuity and risk mitigation" question, recognizable because a key resource is leaving mid-project, and we need a condition that makes accepting the role viable.

Why it applies: Raman's dilemma is that the project takes 6 months, but he leaves in 3. He needs assurance that the project won't fail or reflect poorly on him after his departure.

Step 1: Evaluate Option D. If his subordinates have successfully completed projects during his absence (exams), it proves the team is competent and can sustain the project without him. This directly mitigates the risk of him leaving halfway.

Step 2: Evaluate other options. Option A (past speed) doesn't solve the 3-month vs 6-month gap. Option B (more resources) assumes resources are the bottleneck, which isn't stated. Option C (Suraj advising against) is a reason to reject, not accept. Option E (working weekends) is unsustainable and ignores business school demands.

Common trap: Assuming that adding more resources (Option B) or working harder (Option E) solves a structural timeline mismatch, rather than addressing the core risk of leadership continuity.

Answer: D

Question 9 · Decision Making (DM) MCQ

Common Description:

Read the following scenario and answer the question that follows.

Comprehension: A professor's syllabus explicitly states the conditions for joint assignment submissions: "No more than two students may share the exact same data set, and all listed co-authors must demonstrably contribute to the final written draft." The syllabus does not provide a rubric for partial credit based on contribution levels; it is a pass/fail component for the assignment submission requirement.

Which of the following scenarios makes it IMPOSSIBLE for the professor to approve the submission without violating the explicit conditions of the rule?

A.
Three students submit together, all used different data sets, and all wrote distinct sections of the paper.
B.
Two students submit together, used the same data set, but only one wrote the entire paper while the other claims they provided 'moral support'.
C.
Four students submit as two independent pairs, each pair used a different data set, and all four students wrote sections.
D.
Two students submit together, used different data sets, and both actively wrote and edited the final draft.

Correct Answer:

Step-by-Step Solution

Key idea: This is a boundary condition question, recognizable by a scenario testing the absolute limits of a conditional permission rule.

Step 1: Identify the explicit conditions. Condition 1: Max 2 students per shared data set. Condition 2: ALL listed co-authors must demonstrably contribute to the final written draft.

Step 2: Evaluate Option A. Three students, different data sets (Condition 1 met), all wrote sections (Condition 2 met). Possible to approve.

Step 3: Evaluate Option B. Two students, same data set (Condition 1 met). However, only one wrote the paper, and "moral support" is not a demonstrable contribution to the written draft. This violates Condition 2.

Step 4: Evaluate Options C and D. Both satisfy the requirement that all listed authors contributed to the writing and data set limits are respected.

Step 5: Conclude. Option B is the only scenario that inherently violates a stated condition, making approval impossible without breaking the rule.

Answer: Two students submit together, used the same data set, but only one wrote the entire paper while the other claims they provided 'moral support'.
