IBPS PO (Probationary Officer) Quantitative Aptitude Flashcards
50 question-and-answer cards covering Quantitative Aptitude as it is examined in IBPS PO (Probationary Officer). 24 of them are printed below, taken from across the deck — no signup, no paywall on the preview.
24 sample cards from the Quantitative Aptitude deck
Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.
What is the formula for Simple Interest?
SI = (P × R × T) / 100, where P = principal, R = rate per annum, T = time in years.
What is the formula for Compound Interest (amount) compounded annually?
A = P(1 + R/100)^T; CI = A − P.
How is CI calculated when compounded half-yearly?
Use rate R/2 per period and 2T periods: A = P(1 + R/200)^(2T).
What is the difference between CI and SI for 2 years on principal P at rate R%?
Difference = P(R/100)².
State the basic formula for Average.
Average = (Sum of all observations) / (Number of observations).
What is the Rule of Alligation used to find?
It finds the ratio in which two ingredients at different prices/concentrations must be mixed to get a mixture at a given mean price/concentration.
State the alligation ratio formula.
(Quantity of cheaper) / (Quantity of dearer) = (Dearer price − Mean price) / (Mean price − Cheaper price).
When a vessel of x litres full of liquid has y litres replaced by water n times, what fraction of pure liquid remains?
Remaining pure liquid = x × (1 − y/x)^n.
If the average of n numbers is A and one number is removed, how do you find the new average?
New average = (nA − removed value) / (n − 1).
State the relationship between speed, distance, and time.
Speed = Distance / Time; Distance = Speed × Time; Time = Distance / Speed.
How do you convert km/hr to m/s and vice versa?
km/hr → m/s: multiply by 5/18. m/s → km/hr: multiply by 18/5.
What is the relative speed of two objects moving in the same direction and in opposite directions?
Same direction: difference of speeds. Opposite direction: sum of speeds.
If A can do a work in x days and B in y days, in how many days can they finish it together?
Together in (xy)/(x + y) days; combined one-day work = 1/x + 1/y.
In boats and streams, what are downstream and upstream speeds?
Downstream speed = boat speed + stream speed; Upstream speed = boat speed − stream speed.
What is the average speed for a journey covering equal distances at speeds x and y?
Average speed = 2xy / (x + y) (harmonic mean).
In Tabular DI, what is the first step before attempting calculations?
Read the title, headings, units, and any footnotes carefully to understand exactly what the rows/columns represent and what is given vs. asked.
In a pie chart DI, how do you convert a degree value to an actual quantity?
Quantity = (Sector angle / 360) × Total; or (Sector percentage / 100) × Total.
What does a Caselet DI present, and how is it best approached?
A Caselet gives data as a paragraph of text (no table/graph). Best approached by extracting the numbers into a self-made table or Venn diagram before solving.
In Missing DI, how do you find a blank value in a table?
Use the relationships/conditions given in the question (totals, ratios, percentages between cells) to set up an equation and solve for the missing entry.
In Data Sufficiency, what does it mean when 'Statement I alone is sufficient but II alone is not'?
The question can be answered uniquely using only Statement I, while Statement II by itself does not yield a unique answer.
In Data Sufficiency, why should you avoid actually solving for the final value?
You only need to determine whether a unique answer can be obtained, not compute it — solving fully wastes time. Judge sufficiency, not the value.
What is the standard form of a quadratic equation and its roots formula?
ax² + bx + c = 0; roots x = [−b ± √(b² − 4ac)] / 2a.
For a quadratic ax² + bx + c = 0, what are the sum and product of the roots?
Sum of roots = −b/a; Product of roots = c/a.
In quadratic comparison questions (compare x and y), what conclusion is drawn if the ranges of x and y overlap?
No definite relation can be established between x and y (the answer is 'relationship cannot be determined').
What this deck covers
The Quantitative Aptitude deck follows the IBPS PO (Probationary Officer) Quantitative Aptitude syllabus — 4 chapters and 14 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 12.5 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 84 characters, which is long enough to carry the reasoning and short enough to say out loud.
A deck like this earns its keep on the second and third pass. Read the syllabus first so you know the shape of the subject, then use the cards to find the specific facts that have not stuck.

They follow the IBPS PO (Probationary Officer) Quantitative Aptitude syllabus — 4 chapters and 14 topics — so the questions track what is actually examinable.
How should I use these flashcards?
Read the syllabus first so you know the shape of the subject, then drill the deck. Examius schedules each card with spaced repetition, so cards you keep missing come back sooner and ones you know drift further apart.
