24 sample cards from the Mathematics deck
Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.
How do you find Selling Price from Cost Price and loss percentage?
SP = CP × (100 − Loss%) / 100.
What is markup?
Markup is the amount added to the cost price to set the marked (list) price: Marked Price = Cost Price + Markup.
What is discount and on what is it calculated?
Discount is a reduction given on the marked (list) price. It is calculated as a percentage of the Marked Price, not the cost price.
What is the formula for discount amount and final selling price after discount?
Discount = (Discount% / 100) × Marked Price; Selling Price = Marked Price − Discount.
An item marked at Rs 500 has a 20% discount. What is the selling price?
Discount = 20% of 500 = 100, so Selling Price = 500 − 100 = Rs 400.
What is a ratio?
A ratio is a comparison of two quantities of the same kind by division, written as a:b or a/b.
What is a proportion?
A proportion is a statement that two ratios are equal, written a:b = c:d (or a/b = c/d).
State the rule of cross-multiplication for a proportion a:b = c:d.
In a proportion a:b = c:d, the product of the means equals the product of the extremes: b × c = a × d.
In the proportion 3:4 = x:12, find x.
By cross-multiplication, 4x = 3 × 12 = 36, so x = 9.
What is direct proportion?
Two quantities are in direct proportion when an increase in one causes a proportional increase in the other; their ratio stays constant (y = kx).
What is inverse proportion?
Two quantities are in inverse proportion when an increase in one causes a proportional decrease in the other; their product stays constant (xy = k).
Give a real example of inverse proportion.
Speed and time for a fixed distance: as speed increases, the time taken decreases, since speed × time = distance is constant.
What is the formula for the average (arithmetic mean) of a set of numbers?
Average = (Sum of all observations) / (Number of observations).
Find the average of 4, 8, 10, and 14.
Sum = 36, count = 4, so Average = 36 / 4 = 9.
How do you find the total sum if you know the average and number of items?
Sum = Average × Number of items.
What is the average of the first n natural numbers?
(n + 1) / 2.
What is simple interest?
Interest calculated only on the original principal for the entire time period, without compounding.
State the formula for simple interest.
SI = (P × R × T) / 100, where P is principal, R is rate percent per annum, and T is time in years.
What is the formula for the total amount in simple interest?
Amount = Principal + Simple Interest = P + (P × R × T)/100, or P(1 + RT/100).
Find the simple interest on Rs 1000 at 5% per annum for 2 years.
SI = (1000 × 5 × 2) / 100 = Rs 100.
How do you find the principal if SI, rate and time are known?
P = (SI × 100) / (R × T).
In Time and Work, if a person completes a job in n days, what is their one-day work?
Their one-day (one unit time) work is 1/n of the total job.
If A does a job in 'a' days and B in 'b' days, how long do they take working together?
Together their one-day work is (1/a + 1/b), so time taken = ab / (a + b) days.
A can do a job in 10 days and B in 15 days. How long working together?
Combined one-day work = 1/10 + 1/15 = 1/6, so together they finish in 6 days.
What this deck covers
The Mathematics deck follows the Army Soldier Test Mathematics syllabus — 7 chapters and 23 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 7.1 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 78 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.
Mathematics flashcards FAQ
How many Mathematics flashcards are in this Army Soldier Test deck?
50 cards. This page previews 24 of them, sampled evenly across the deck so you can judge the difficulty before installing anything.
Are these Army Soldier Test flashcards free?
Yes. The preview here is free to read with no signup, and the full 50-card deck is free inside the Examius app.
What do the Mathematics cards cover?
They follow the Army Soldier Test Mathematics syllabus — 7 chapters and 23 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.
