Mettl Aptitude Assessment — Questions and Answers

Question 1: A train leaves Station A at 9:00 AM traveling east at 60 mph. Another train leaves Station B (180 miles east of A) at the same time traveling west at 30 mph. At what time do they meet?

10:30 AM
10:00 AM
11:00 AM (Correct answer)
12:00 PM

Correct answer: 11:00 AM

Combined speed is 90 mph; 180 miles ÷ 90 mph = 2 hours, so they meet at 11:00 AM.

Question 2: Some doctors are teachers. All teachers are graduates. Conclusion I: Some doctors are graduates. Conclusion II: All graduates are doctors. Which is correct?

Only Conclusion II follows
Only Conclusion I follows (Correct answer)
Both conclusions follow
Neither conclusion follows

Correct answer: Only Conclusion I follows

Some doctors are teachers and all teachers are graduates, so some doctors must be graduates; the converse 'all graduates are doctors' is not implied.

Question 3: Select the sentence that correctly uses 'who' vs. 'whom':

Whom called the meeting to order?
Who did you speak with about the promotion? (Correct answer)
To who should I address the complaint?
Whom is responsible for this error?

Correct answer: Who did you speak with about the promotion?

'Whom did you speak with' is correct since 'whom' is the object of the preposition 'with,' and the sentence restructured shows this.

Question 4: What is the value of x + y? Statement 1: x + 2y = 10 Statement 2: 2x + y = 8 Which of the following is correct?

Statement 1 alone is sufficient to answer the question
Both statements together are sufficient, but neither alone is (Correct answer)
Statement 2 alone is sufficient to answer the question
Even both statements together are not sufficient to answer the question

Correct answer: Both statements together are sufficient, but neither alone is

Adding both equations: (x + 2y) + (2x + y) = 10 + 8 → 3x + 3y = 18 → x + y = 6. Neither statement alone gives x + y, but adding them together yields the answer directly without needing individual values of x and y.

Question 5: A table compares Q1 and Q2 revenue for three regions: North ($500K→$600K), South ($300K→$270K), East ($400K→$440K). Which region had the highest percentage growth?

North (Correct answer)
East
North and East tied
South

Correct answer: North

North grew 20%, East grew 10%, and South declined 10%, making North the highest growth region.

Question 6: A data table shows that Customer Acquisition Cost (CAC) rose from $120 to $150 while Customer Lifetime Value (LTV) rose from $480 to $525. Which metric improved most in percentage terms?

LTV improved more
CAC worsened while LTV improved (Correct answer)
Both improved by the same percentage
CAC improved more

Correct answer: CAC worsened while LTV improved

CAC rose 25% (unfavorable increase in cost); LTV rose 9.375% (favorable) — CAC worsened, LTV improved.

Question 7: Read the passage: 'Despite the exhaustive research conducted over three decades, scientists remain divided on the root causes of the phenomenon.' What does 'exhaustive' mean here?

Thorough and comprehensive (Correct answer)
Tiring and draining
Recent and cutting-edge
Inconclusive and flawed

Correct answer: Thorough and comprehensive

In this context, 'exhaustive' means thorough and comprehensive, covering all aspects of the subject.

Question 8: In a series, shapes gain one vertex per step: step 1 = triangle, step 2 = square, step 3 = pentagon. What shape appears at step 7?

Decagon
Heptagon
Octagon
Nonagon (Correct answer)

Correct answer: Nonagon

Step 1 = 3 sides; each step adds 1, so step 7 = 3 + 6 = 9 sides = nonagon.

Question 9: What is the meaning of the idiom 'burn the midnight oil'?

Cook food at midnight
Work very late into the night (Correct answer)
Waste energy carelessly
Start a fire late at night

Correct answer: Work very late into the night

To burn the midnight oil means to stay up late working or studying.

Question 10: A line graph shows a company's stock price over 6 months. The price was $50 in Month 1 and $65 in Month 6, with no clear straight-line trend between. Which statement is most accurate?

The stock grew at a constant rate
The stock never dipped below $50
The average monthly price was $57.50
The net change was +$15 but intra-period volatility is unknown from this info (Correct answer)

Correct answer: The net change was +$15 but intra-period volatility is unknown from this info

Only endpoint values are stated; intra-period movements cannot be determined from two data points alone.

Question 11: A chart shows that 3 out of every 8 employees work remotely. In a company of 480 employees, how many work on-site?

160
180
300 (Correct answer)
240

Correct answer: 300

Remote workers = (3/8)×480=180; on-site = 480−180 = 300.

Question 12: Which technique is most appropriate when testing a login system that locks an account after 3 failed attempts?

Cause-Effect Graphing
Boundary Value Analysis
State Transition Testing (Correct answer)
Equivalence Partitioning

Correct answer: State Transition Testing

Correct answer: Merge Sort

Merge Sort runs in O(n log n) average-case, outperforming the O(n²) algorithms.

Question 14: A line graph shows two product revenue lines crossing in June. Product A starts higher in January. What does the crossing point indicate?

Product A revenue exceeds Product B for the first time
Product B revenue equals Product A revenue (Correct answer)
Both products have zero revenue
Product A revenue falls to zero

Correct answer: Product B revenue equals Product A revenue

A crossing point on a line graph means the two values are equal at that moment.

Question 15: Consider the following statements: 'If the server is online, then the website is accessible. The website is not accessible.' Based on these statements, which of the following conclusions is logically certain?

The server status is unknown.
The server is offline. (Correct answer)
The website will be accessible soon.
The server is online.

Correct answer: The server is offline.

This is an example of a valid logical argument form called Modus Tollens. If the first statement (If P, then Q) is true, and the second part (Q) is false, then the first part (P) must also be false. Since the website is not accessible (not Q), the server must not be online (not P).

Question 16: Select the correct meaning of the idiom: 'To bite the bullet'.

To make a rash decision
To challenge someone aggressively
To take a significant financial risk
To endure a painful situation with courage (Correct answer)

Correct answer: To endure a painful situation with courage

'To bite the bullet' means to endure a painful or difficult situation stoically rather than avoiding it.

Question 17: A shipping label includes Tracking #: AB123456789CD. If the system requires exactly 12 alphanumeric characters, what is wrong?

Nothing is wrong with the tracking number
The tracking number has 13 characters instead of 12 (Correct answer)
The weight field is missing
The dimensions are out of range

Correct answer: The tracking number has 13 characters instead of 12

Counting A-B-1-2-3-4-5-6-7-8-9-C-D gives 13 characters, one more than the required 12.

Question 18: A spreadsheet shows Q1: $45,200; Q2: $52,100; Q3: $48,750; Q4: $61,300. The annual total is listed as $208,350. Is this correct?

No, the total should be $209,350
No, the total should be $207,350 (Correct answer)
No, the total should be $206,350
Yes, the total is correct

Correct answer: No, the total should be $207,350

45,200 + 52,100 + 48,750 + 61,300 = $207,350, not $208,350 as stated.

Question 19: Which of these is the most accurate description of 'emotional hijacking' (amygdala hijack)?

Deliberately using emotions to manipulate others
A sudden emotional reaction that bypasses rational thinking (Correct answer)
A therapeutic technique for processing trauma
The process of suppressing emotions until they explode

Correct answer: A sudden emotional reaction that bypasses rational thinking

An amygdala hijack occurs when a strong emotional stimulus triggers the amygdala to override the prefrontal cortex, resulting in reactive rather than reasoned behavior.

Question 20: Which workplace behavior is most associated with low emotional intelligence?

Taking a short break when feeling overwhelmed
Acknowledging uncertainty during a team decision
Blaming others consistently when projects fail (Correct answer)
Asking clarifying questions during conflict

Correct answer: Blaming others consistently when projects fail

Consistent blame-shifting reflects poor self-awareness and an inability to regulate emotions like defensiveness, both markers of low EI.

Neither the manager nor the employees were informed about the policy change. (Correct answer)
Neither the manager nor the employees have been informed about the policy change.

Correct answer: Neither the manager nor the employees were informed about the policy change.

In 'neither…nor' constructions, the verb agrees with the subject closest to it (the 'nor' subject). 'The employees' is plural, so the verb must be plural: 'were.' Options A, C, and D use singular or incorrect forms.

Question 24: Two candidates have identical Conscientiousness scores. Candidate A is high in Extraversion; Candidate B is high in Introversion. Which role would Candidate B likely outperform in?

Corporate sales territory management
High-volume customer service representative
Independent research analyst requiring deep focused work (Correct answer)

3 hours 30 minutes
2 hours 50 minutes
3 hours 20 minutes (Correct answer)
3 hours 10 minutes

Correct answer: 3 hours 20 minutes

Original speed = 360/4 = 90 km/h. New speed = 90 × 1.20 = 108 km/h. Time = 360/108 = 3.33 hours = 3 hours 20 minutes.

Question 32: A pie chart shows company expenses: Salaries 40%, Rent 20%, Marketing 15%, Operations 15%, Miscellaneous 10%. If total expenses are ₹10 lakh, how much is spent on Rent and Marketing combined?
