If you cannot clear the aptitude round, your coding skills and communication abilities never get a chance to shine. This guide covers 50+ aptitude questions with answers across all four categories — quantitative aptitude, verbal ability, logical reasoning, and data interpretation.

Whether you are preparing for placement aptitude test questions or aptitude interview questions, these are the types you will face. Every aptitude questions for interview round follows a predictable pattern — companies recycle question types year after year. The numbers change, the logic stays the same.

This is not a theory guide. Every question below comes with a step-by-step solution and a shortcut method. Use this for aptitude practice before your next placement drive or job interview.

“80% of aptitude test questions repeat the same patterns. Learn the pattern once, solve any variation in 30 seconds.”

Quantitative Aptitude — Aptitude Numerical Ability (15 Questions)

Aptitude numerical ability is the highest-weighted section in every placement test. TCS gives 26 questions from this section alone. Master percentages, profit & loss, time & work, speed-distance-time, and number series — and you cover 80% of what companies ask.

Percentages (3 Questions)

Q1: A shopkeeper marks a product 40% above cost price and gives a 20% discount. Find the profit percentage.

Let CP = 100
Marked Price = 100 + 40% of 100 = 140
Discount = 20% of 140 = 28
Selling Price = 140 - 28 = 112
Profit = 112 - 100 = 12
Profit % = (12/100) × 100 = 12%

Shortcut: Successive % formula
Net effect = 40 - 20 - (40×20)/100
           = 40 - 20 - 8 = 12%

Answer: 12% profit

Q2: If the price of petrol increases by 25%, by what percentage should a person reduce consumption to keep expenditure the same?

Shortcut formula:
Reduction % = (increase / (100 + increase)) × 100
            = (25 / 125) × 100
            = 20%

Step-by-step:
Let original price = 100, consumption = 1 unit
Original expenditure = 100
New price = 125
New consumption = 100/125 = 0.8 units
Reduction = (1 - 0.8)/1 × 100 = 20%

Answer: 20% reduction

Q3: In an election between two candidates, 20% of voters did not vote. Candidate A got 60% of votes polled. He won by 2400 votes. Find total voters.

Let total voters = x
Votes polled = 80% of x = 0.8x
A got 60% of 0.8x = 0.48x
B got 40% of 0.8x = 0.32x
Difference = 0.48x - 0.32x = 0.16x

0.16x = 2400
x = 15,000

Answer: 15,000 total voters

Companies that ask this: TCS NQT, Cognizant GenC

Profit & Loss (3 Questions)

Q4: A man buys 10 oranges for ₹50 and sells 8 oranges for ₹50. Find profit %.

CP of 1 orange = 50/10 = ₹5
SP of 1 orange = 50/8 = ₹6.25
Profit per orange = 6.25 - 5 = ₹1.25
Profit % = (1.25/5) × 100 = 25%

Shortcut: When amount is same
Profit % = ((10-8)/8) × 100 = (2/8) × 100 = 25%

Answer: 25% profit

Q5: By selling a watch for ₹1140, a man loses 5%. At what price should he sell to gain 5%?

SP = ₹1140, Loss = 5%
CP = SP / (1 - Loss%) = 1140 / 0.95 = ₹1200
For 5% gain: SP = CP × 1.05 = 1200 × 1.05 = ₹1260

Shortcut ratio method:
Loss SP : Gain SP = (100-5) : (100+5) = 95 : 105
1140/95 = 12 → 12 × 105 = ₹1260

Answer: ₹1260

Q6: A trader mixes 30 kg of rice at ₹40/kg with 20 kg at ₹60/kg. At what price should he sell the mixture to gain 20%?

Total CP = (30 × 40) + (20 × 60)
         = 1200 + 1200 = ₹2400
Total weight = 50 kg
CP per kg = 2400/50 = ₹48
For 20% gain: SP per kg = 48 × 1.20 = ₹57.60

Answer: ₹57.60 per kg

Time & Work (3 Questions)

Q7: A can do a job in 12 days, B in 15 days. They work together for 4 days, then A leaves. How many more days does B take to finish?

A's rate = 1/12 per day
B's rate = 1/15 per day
Together = 1/12 + 1/15 = (5+4)/60 = 9/60 = 3/20

Work done in 4 days = 4 × 3/20 = 12/20 = 3/5
Remaining work = 1 - 3/5 = 2/5

B alone: (2/5) ÷ (1/15) = (2/5) × 15 = 6 days

Answer: 6 more days

Companies that ask this: TCS NQT, Infosys

Q8: 12 men can complete a work in 18 days. After 6 days, 4 more men join. How many more days to finish?

Total work = 12 × 18 = 216 man-days
Work done in 6 days = 12 × 6 = 72 man-days
Remaining = 216 - 72 = 144 man-days
New workforce = 12 + 4 = 16 men
Days needed = 144/16 = 9 days

Answer: 9 more days

Q9: A pipe fills a tank in 6 hours, another empties it in 8 hours. If both are open, how long to fill the tank?

Fill rate = 1/6 per hour
Empty rate = 1/8 per hour
Net rate = 1/6 - 1/8 = (4-3)/24 = 1/24

Time to fill = 24 hours

Answer: 24 hours

Speed, Distance & Time (3 Questions)

Q10: A train 150m long passes a pole in 15 seconds. Find its speed in km/h.

Speed = Distance / Time
     = 150 / 15 = 10 m/s

Convert to km/h: 10 × (18/5) = 36 km/h

Shortcut: m/s to km/h → multiply by 3.6
10 × 3.6 = 36 km/h

Answer: 36 km/h

Q11: Two trains 200m and 300m long run in opposite directions at 40 km/h and 50 km/h. Time to cross each other?

Total distance = 200 + 300 = 500m
Relative speed (opposite) = 40 + 50 = 90 km/h
Convert: 90 × (5/18) = 25 m/s

Time = 500/25 = 20 seconds

Answer: 20 seconds

Companies that ask this: TCS, Wipro

Q12: A person covers half the distance at 40 km/h and the other half at 60 km/h. Find average speed.

Shortcut for equal distances:
Average speed = 2ab/(a+b)
             = 2 × 40 × 60 / (40 + 60)
             = 4800 / 100
             = 48 km/h

Note: Average speed ≠ average of speeds
(40+60)/2 = 50 ← WRONG

Answer: 48 km/h

Number Series (3 Questions)

Q13: Find the next number: 2, 6, 12, 20, 30, ?

Differences: 4, 6, 8, 10, ?

    └── married to E
B is A's child → D is B's uncle → E is B's aunt
Answer: B is E's nephew/niece

Q31: If P + Q means P is father of Q,
     P - Q means P is wife of Q,
     P × Q means P is brother of Q,
     then what does A + B - C mean?
A + B → A is father of B
B - C → B is wife of C
So: A is father of B, B is married to C
A is C's father-in-law
Answer: A is father-in-law of C

Placement Tips — Company-Wise Aptitude Patterns

Every company has a different aptitude test format. Knowing the pattern before you walk in gives you a massive advantage. Here is what the top recruiters actually test and how to manage your time for aptitude questions for placement drives.

Company-Wise Aptitude Test Format

TCS NQT (60 min)

  • • Numerical: 26 questions
  • • Verbal: 24 questions
  • • Reasoning: 30 questions
  • • No negative marking
  • • Sectional time limits

Infosys InfyTQ (65 min)

  • • Quantitative: 15 questions
  • • Logical: 15 questions
  • • Verbal: 20 questions
  • • No negative marking
  • • Higher verbal weightage

Wipro NLTH (48 min)

  • • Aptitude: 20 questions
  • • Logical: 14 questions
  • • Verbal: 14 questions
  • • Negative marking: -1
  • • Fastest time pressure

Time Management Strategy

Average 1 minute per question. If you are stuck for more than 90 seconds, skip and return. Mark questions you skip so you can find them quickly. In aptitude practice sessions, always use a timer — solving without time pressure builds false confidence.

  • First pass (70% of time): Solve all easy and medium questions. Skip anything that takes more than 90 seconds.
  • Second pass (30% of time): Return to skipped questions. Use elimination to narrow options.
  • Last 2 minutes: Guess remaining unanswered questions (if no negative marking).

Where to Practice Aptitude Questions

  • IndiaBix: Largest free collection of aptitude questions and answers. Good for topic-wise practice.
  • PrepInsta: Company-specific previous year papers. Best for TCS, Infosys, Wipro patterns.
  • GeeksforGeeks: Aptitude section with explanations. Good for logical reasoning and puzzles.
  • Modncv Interview Prep: AI-powered aptitude practice with instant feedback and performance tracking.

Common Mistakes to Avoid

  • Not reading the question fully: Many aptitude test questions have tricky wording. “What is NOT true” vs “What is true” changes the answer completely.
  • Spending too long on one question: One hard question is worth the same as one easy question. Move on.
  • Not practicing under time pressure: Solving 50 questions in 3 hours is not the same as solving 50 in 60 minutes.
  • Ignoring verbal and reasoning: Most students only practice quantitative. Verbal and reasoning are equally weighted.
  • Not learning shortcuts: Every aptitude question type has a shortcut formula. Learn them — they save 30-40 seconds per question.
