Deloitte Aptitude Pattern and Important Topics: 2026 Guide

Deloitte’s campus aptitude test runs 75 questions across three equal sections in 95 minutes, with no negative marking. Students heading into Deloitte’s campus recruitment process will typically encounter 25 questions each in Quantitative Aptitude, Verbal Ability, and Logical Reasoning. The exact count can vary slightly between drives and campus batches, so confirm the latest pattern with your placement cell before the test day.

Quantitative Aptitude: 25 Questions

The quantitative section covers four well-defined topic clusters. Deloitte does not test advanced quant at this stage. Focused practice on the four areas below is enough preparation.

Profit and Loss

Questions involve mark-up calculations, successive discounts, and cost-price variations across chains of transactions. Three formulas cover most scenarios:

• Profit percentage = (Profit / Cost Price) x 100
• Selling Price = Cost Price x (1 + Profit percentage / 100)
• For successive discounts of a% and b%, the net discount = a + b - (ab / 100)

Expect 5 to 7 questions from profit and loss in a standard 25-question aptitude set.

Percentages

Percentage problems in Deloitte campus drives often chain two or three changes in sequence. Converting each change to a decimal multiplier is the efficient approach. For example:

• A 20% increase followed by a 15% decrease = multipliers 1.20 x 0.85 = 1.02, a net 2% increase.

Multiplying through avoids recalculating from scratch at each step, which matters under the 95-minute time limit.

Logarithms

Log questions test change-of-base rules and the three standard log laws:

• log(ab) = log a + log b
• log(a/b) = log a - log b
• log(a raised to n) = n log a

If logarithms are a weak point, two focused practice sessions on these three laws cover nearly every log question Deloitte has tested. Practice Deloitte aptitude questions with answers to test your speed across log, percentage, and profit-and-loss problems.

Probability

Probability questions here use cards, dice, or ball-from-bag setups based on combination formulas. Weighted distributions and conditional probability rarely appear at this test level. Build fluency with C(n,r) calculations and simple outcome enumeration.

Verbal Ability: 25 Questions

The verbal section tests vocabulary range and reading endurance in roughly equal measure. Students who treat vocabulary work as optional tend to lose points here.

Synonyms and Antonyms

Six to eight questions draw from a mid-difficulty vocabulary list. Words like “loquacious,” “acrimonious,” “penury,” and “equanimity” appear frequently across campus drives. A 15-minute daily vocabulary session for three weeks covers the required range without requiring a dictionary-sized word list.

Sentence Correction

Questions ask you to identify a grammatical error or select the most effective sentence from four options. The key areas tested are: subject-verb agreement, pronoun reference, parallel structure, and dangling modifiers. Practise identifying each error type in isolation before moving to mixed practice sets.

Reading Comprehension

RC passages run 200 to 300 words with three to four questions each. A useful reading order: skim the passage for the main idea in 30 seconds, read all questions, then return to the passage to locate specific answers. Reading the questions first tells you what to scan for on the second pass, which cuts total time per passage compared to a linear read-through.

Logical Reasoning: 25 Questions

This section is where time management separates candidates more than raw knowledge does.

Age Problems

Age problems present two unknowns with a current-ratio condition and a future or past condition. They resolve cleanly as a two-equation system:

• Step 1: Assign variables for current ages, for example x and y.
• Step 2: Write Equation 1 from the given current ratio (x / y = p / q).
• Step 3: Write Equation 2 from the past or future condition, for example (x - n) / (y - n) = r / s.
• Step 4: Solve the two-equation system for x and y.

This setup becomes automatic with practice. Candidates who have drilled age problems consistently solve them in 60 to 90 seconds.

Data Interpretation

DI is the most time-intensive part of the section. Each set presents a table or bar chart followed by three to five calculation questions. The right strategy is a hard time cut-off: if a DI set runs past 3 minutes, flag it and move to the next question. Attempting all single-answer LR questions first locks in points before a difficult DI set consumes your time buffer. Come back to flagged sets if time remains.

The CoCubes Platform: What Adaptive Testing Means

Deloitte’s campus tests run on the CoCubes platform (now HirePro), which is an adaptive online system. Adaptive means the platform adjusts question difficulty based on your responses as you progress. Two practical consequences:

• Accuracy on the first few questions of each section carries more weight than speed on later ones. A string of early incorrect answers can shift the difficulty band in a direction that affects your sectional score.
• On standard CoCubes delivery, you cannot return to a previous question after moving forward. Confirm this restriction with your placement coordinator before the drive, since some drives configure the platform differently.

No negative marking changes the strategy completely. Leaving any question unanswered is always the wrong choice. When uncertain between two options, narrow by elimination and commit. A committed guess on a narrowed two-option shortlist is strictly better than an empty answer.

A Four-Week Preparation Plan

Approach each week with a single section in focus rather than attempting all three simultaneously.

Week 1: Cover quantitative fundamentals. Work through profit and loss, percentages, logarithms, and probability in sequence. Drill 25 to 30 problems per topic before advancing. Avoid timed drills this week; accuracy and formula familiarity come first.

Week 2: Shift to logical reasoning. Practice age-problem setups until the simultaneous-equation form is automatic. Then move to data interpretation: target four DI questions in under four minutes per set. DI speed comes from repeated mental arithmetic with bar and table data, not from shortcuts.

Week 3: Work through the verbal section. Run a daily 15-minute vocabulary session using synonym and antonym flashcards. Practise two RC passages per day under a 6-minute timer, using the skim-then-locate method described above.

Week 4: Take at least three full 75-question mocks at 95 minutes each. After every mock, identify which section consumed excess time and adjust your section-level timing plan. Review Deloitte placement papers with solutions for company-specific question patterns in the final week before your drive.

The same systematic reasoning Deloitte tests in the DI and probability sections, breaking a data set into smaller steps to reach a defensible conclusion, is the foundation companies increasingly value when engineers work with AI tools rather than just using them as black boxes.
