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 Simple Interest formula?
SI = (P × R × T) / 100, where P = principal, R = rate per annum, T = time in years. Amount = P + SI.
What is the Compound Interest formula (compounded annually)?
Amount A = P(1 + R/100)^T, and CI = A − P.
For compounding more than once a year, how is the CI amount formula adjusted?
A = P(1 + R/(n×100))^(n×T), where n = number of times interest is compounded per year (e.g., n=2 for half-yearly, n=4 for quarterly).
What is the difference between CI and SI for 2 years on principal P at rate R%?
CI − SI (for 2 years) = P × (R/100)².
What is a ratio and what is a proportion?
A ratio compares two quantities of the same kind by division (a:b = a/b). A proportion states two ratios are equal (a:b = c:d), where a and d are extremes, b and c are means.
In a proportion a:b = c:d, what key product relationship holds?
Product of extremes = product of means, i.e., a × d = b × c (cross multiplication).
What is the mean proportional between two numbers a and b?
The mean proportional = √(a × b).
If A can do a work in 'a' days and B in 'b' days, how long do they take working together?
Together they take ab/(a+b) days, since their combined one-day work = 1/a + 1/b.
In time and work, what is the relationship between efficiency and time taken?
Efficiency is inversely proportional to time. If A is twice as efficient as B, A takes half the time B takes; ratio of efficiencies = inverse ratio of times.
What is the basic 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 m/s to km/hr?
km/hr to m/s: multiply by 5/18. m/s to km/hr: multiply by 18/5.
What is relative speed for two objects moving in the same direction versus opposite directions?
Same direction: relative speed = difference of speeds (s₁ − s₂). Opposite directions: relative speed = sum of speeds (s₁ + s₂).
What is the average speed when equal distances are covered at speeds x and y?
Average speed = 2xy/(x+y) (the harmonic mean), not the simple average of the two speeds.
What is the formula for average (arithmetic mean)?
Average = (Sum of all observations) / (Number of observations).
What happens to the average if a constant k is added to each observation in a set?
The new average also increases by k (the average shifts by the same constant).
What is the average of the first n natural numbers?
Average = (n + 1) / 2.
What is the average of first n consecutive even numbers and first n consecutive odd numbers?
Average of first n even numbers = (n + 1). Average of first n odd numbers = n.
What does a multiplication table represent in arithmetic, and why is memorizing tables useful in aptitude?
A table lists the multiples of a number (e.g., table of 7: 7,14,21,...). Memorizing tables up to 20–30 speeds up calculations in approximation, ratio, and data interpretation questions.
What is a bar graph and what is it best used for?
A bar graph uses rectangular bars of equal width whose lengths/heights are proportional to the values they represent. It is best for comparing discrete categories of data.
What is a line graph primarily used to represent?
A line graph displays data points connected by straight lines, best used to show trends or changes in a quantity over time (continuous data).
What does a pie chart represent and how many degrees correspond to the whole?
A pie chart shows data as sectors of a circle, each proportional to its share of the total. The whole circle = 360°, so each category's angle = (value/total) × 360°.
In a pie chart, how do you convert a percentage share into the central angle of its sector?
Central angle = (percentage / 100) × 360°. Equivalently, 1% corresponds to 3.6°.
In data interpretation, what is the formula to find the percentage one quantity is of the total?
Percentage = (Part / Total) × 100. Used heavily in pie charts, bar graphs, and tables to compute shares.
What is the difference between an expression and an equation, and between linear and quadratic equations by degree?
An expression has no equality sign; an equation states two expressions are equal. A linear equation has highest degree 1 (one variable: ax+b=0); a quadratic equation has highest degree 2 (ax²+bx+c=0).
What this deck covers
The Quantitative Aptitude deck follows the IBPS PO Quantitative Aptitude syllabus — 5 chapters and 18 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 9.8 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 103 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.
Quantitative Aptitude flashcards FAQ
How many Quantitative Aptitude flashcards are in this IBPS PO deck?
49 cards. This page previews 24 of them, sampled evenly across the deck so you can judge the difficulty before installing anything.
Are these IBPS PO flashcards free?
Yes. The preview here is free to read with no signup, and the full 49-card deck is free inside the Examius app.
What do the Quantitative Aptitude cards cover?
They follow the IBPS PO Quantitative Aptitude syllabus — 5 chapters and 18 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.
