51 question-and-answer cards covering Quantitative Aptitude as it is examined in SSC CHSL. 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.
Define cost price, selling price, profit and loss.
Cost Price (CP) = price paid; Selling Price (SP) = price sold. Profit = SP - CP (when SP > CP); Loss = CP - SP (when CP > SP).
Profit% and Loss% are calculated on which value, and give the formulas.
Both are calculated on Cost Price. Profit% = (Profit/CP) x 100; Loss% = (Loss/CP) x 100.
Formula relating SP, CP and Profit% (and Loss%).
SP = CP x (100 + Profit%)/100; for loss, SP = CP x (100 - Loss%)/100.
Define marked price and discount; how is discount calculated?
Marked Price (MP) is the listed price. Discount = MP - SP, and Discount% = (Discount/MP) x 100.
What is the dishonest dealer's gain% when using false weight?
Gain% = (Error / (True value - Error)) x 100, where error is the shortfall in the weight given.
Simple Interest formula.
SI = (P x R x T) / 100, where P = principal, R = rate per annum, T = time in years.
Compound Interest amount formula (annual compounding).
A = P(1 + R/100)^T; CI = A - P.
For 2 years, what is the difference between CI and SI on principal P at rate R%?
Difference = P x (R/100)^2.
How do you adjust the CI formula for half-yearly compounding?
Use rate R/2 and time 2T: A = P(1 + R/200)^(2T).
Compare SI and CI for the same P, R, T over more than one year.
CI is always greater than SI (after the first period) because interest is earned on accumulated interest; for the first year they are equal.
Basic Time and Work relationship: if a person does work in n days, what is one day's work?
One day's work = 1/n of the total work.
If A does a job in x days and B in y days, how long together?
Together they take (xy)/(x+y) days; combined one-day work = 1/x + 1/y.
State the work-equivalence (M1 D1 H1 / W1 = M2 D2 H2 / W2) formula in words.
Men x Days x Hours per day, divided by Work done, is constant — used to relate two work situations.
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.
Pipes and cisterns: how do filling and emptying pipes combine?
Filling pipes add to the rate (positive), emptying pipes subtract (negative); net rate = sum of individual rates.
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.
Fundamental relation between speed, distance and time.
Speed = Distance / Time; Distance = Speed x Time; Time = Distance / Speed.
Average speed for equal distances at speeds x and y.
Average speed = 2xy/(x+y) (harmonic mean), not the simple average.
Time for a train of length L to cross a platform of length P at speed S.
Time = (L + P) / S. To cross a pole, time = L / S.
Boats and streams: downstream and upstream speed formulas.
If boat speed = b and stream = s: downstream = b + s, upstream = b - s. So b = (down+up)/2, s = (down-up)/2.
State the relative speed for two objects moving in the same direction and in opposite directions.
Same direction: difference of speeds. Opposite direction: sum of speeds.
Area and perimeter of a circle, and area of a triangle.
Circle area = πr^2, circumference = 2πr. Triangle area = (1/2) x base x height.
Total surface area and volume of a cylinder.
Volume = πr^2h; Total surface area = 2πr(r + h).
In Data Interpretation, how do you read a pie chart value and find percentage represented by a sector?
Each sector's central angle out of 360 degrees gives its share: percentage = (sector angle / 360) x 100; value = that fraction x total.
What this deck covers
The Quantitative Aptitude deck follows the SSC CHSL Quantitative Aptitude syllabus — 1 chapters and 12 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 51.0 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 80 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 SSC CHSL deck?
51 cards. This page previews 24 of them, sampled evenly across the deck so you can judge the difficulty before installing anything.
Are these SSC CHSL flashcards free?
Yes. The preview here is free to read with no signup, and the full 51-card deck is free inside the Examius app.
What do the Quantitative Aptitude cards cover?
They follow the SSC CHSL Quantitative Aptitude syllabus — 1 chapters and 12 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.
