Overview
Why Aptitude Matters in Placements

Almost every major IT company — from TCS and Infosys to Google and Amazon — filters candidates through an aptitude round before the technical interview.

Aptitude tests measure your ability to process information quickly and accurately under time pressure. They are not about memorising formulas — they test how you think.

Campus placement aptitude rounds typically consist of three sections: Quantitative Ability, Logical Reasoning, and Verbal Ability. Each section is time-limited and scored separately. Sectional cut-offs are common.

This guide covers every core topic, gives you a structured 6-week preparation plan, shares speed-math shortcuts, reasoning frameworks, and company-specific patterns.

Core Topics
What the Test Actually Covers

These eight areas appear consistently across TCS, Wipro, Infosys, Accenture, Cognizant, and product-based company OA rounds.

🔢

HCF, LCM, divisibility, remainders
⏱️
Time, Speed & Distance
Trains, boats, relative motion
📊
Data Interpretation
Bar, pie, line charts, tables
🧩
Logical Reasoning
Syllogisms, blood relations, puzzles
📐
Geometry & Mensuration
Areas, volumes, coordinate geometry
📈
Profit, Loss & Percentages
Discount, markup, percentage change
🎲
Probability & Combinations
PnC, basic probability, Bayes
📝
Verbal Ability
RC, sentence completion, grammar

Key Formula Sheet

Time · Speed · Distance
Speed = Distance ÷ Time
Relative speed: same dir → subtract; opposite → add.
Profit & Loss
Profit% = (Profit ÷ CP) × 100
Successive discounts: a + b − (ab/100). Never add directly.
Simple Interest
SI = (P × R × T) ÷ 100
CI uses (1 + R/100)ⁿ.
Work & Time
1/A + 1/B = 1/T
LCM method: set total work = LCM of individual times.
Permutations
nPr = n! ÷ (n−r)!
Order matters. Circular: (n−1)!
Combinations
nCr = n! ÷ (r! × (n−r)!)
Order does NOT matter.
Percentage Change
Change% = (Change ÷ Original) × 100
Watch the denominator — common error source.
Mixtures & Alligation
Ratio = (d₂−dm) : (dm−d₁)
Fastest method for mixture problems.

TechniqueWhen to UseExample
Vedic SquaringNumbers ending in 575² → (7×8)=56, append 25 → 5625
Cross MultiplicationFraction comparison3/7 vs 4/9 → 27 vs 28 → 4/9 bigger
Percent via Base 10Any percentage32% of 450 → 10%=45, 30%=135, 2%=9 → 144
LCM Work MethodWork-and-timeSet total work = LCM, find daily work of each
Boat Upstream FormulaBoat and streamSpeed in still water = (downstream + upstream)/2

Logical Reasoning
Pattern Recognition and Structured Thinking

Types of Logical Reasoning Questions

🔗
Syllogisms
Use Venn diagrams to derive valid conclusions.
🩸
Blood Relations
Map family trees systematically with symbols.
🪑
Seating Arrangements
Fix one person, fill clues in order.
🔢
Series & Sequences
Check differences, ratios, alternating patterns.
🗺️
Directions
Draw cardinal map, track turns and distances.
🔐
Coding-Decoding
Find the shift pattern: Caesar, reverse, position.
Study Plan
6-Week Placement Aptitude Roadmap

A structured framework to go from zero to placement-ready in 42 days — assuming 2–3 hours of daily focused practice.

Week 1–2
Foundation — Quantitative Core
Cover Number Systems, HCF/LCM, percentages, ratio/proportion, SI/CI. Do 30 questions per topic. Focus on accuracy first.
Week 3
Speed Topics — Arithmetic Clusters
TSD, Time and Work, Boats, Pipes, Mixtures. Practise shortcuts aggressively. Target under 45 seconds per question.
Week 4
Logical Reasoning Blitz
All reasoning types: seating, blood relations, syllogisms, series, coding-decoding. 20 puzzles per type minimum.
Week 5
Data Interpretation + Verbal
Full DI sets timed at 6 min per set. Verbal: RC, para-jumbles, sentence correction. Read one editorial daily.
Week 6
Mock Tests + Company-Specific Drill
One full-length mock daily. Review all wrong answers. Solve previous year papers of your target company.
