LIC AAO Quantitative Aptitude Flashcards
50 question-and-answer cards covering Quantitative Aptitude as it is examined in LIC AAO. 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.
When a quadratic ax^2 + bx + c = 0, what is the quadratic formula for its roots?
x = [-b +/- sqrt(b^2 - 4ac)] / (2a).
For ax^2 + bx + c = 0, what are the sum and product of the roots?
Sum of roots = -b/a; Product of roots = c/a.
What does the discriminant D = b^2 - 4ac tell you about a quadratic's roots?
D > 0: two distinct real roots; D = 0: two equal (repeated) real roots; D < 0: no real roots (complex conjugate roots).
State the identity for (a + b)^2 and (a - b)^2.
(a + b)^2 = a^2 + 2ab + b^2; (a - b)^2 = a^2 - 2ab + b^2.
State the identity for a^2 - b^2 and a^3 + b^3.
a^2 - b^2 = (a + b)(a - b); a^3 + b^3 = (a + b)(a^2 - ab + b^2).
What is the expansion of (a + b + c)^2?
a^2 + b^2 + c^2 + 2ab + 2bc + 2ca.
What are the area and perimeter formulas for a rectangle and the area of a triangle?
Rectangle: Area = length x breadth, Perimeter = 2(l + b). Triangle: Area = (1/2) x base x height.
What are the circumference and area of a circle of radius r?
Circumference = 2(pi)r; Area = (pi)r^2.
What is the area of a trapezium and the area of an equilateral triangle of side a?
Trapezium area = (1/2)(sum of parallel sides) x height. Equilateral triangle area = (sqrt 3 / 4) a^2.
What are the volume and total surface area of a cube of side a?
Volume = a^3; Total Surface Area = 6a^2.
What are the volume and curved surface area of a cylinder (radius r, height h)?
Volume = (pi)r^2h; Curved Surface Area = 2(pi)rh; Total Surface Area = 2(pi)r(h + r).
What are the volume and surface area of a sphere of radius r?
Volume = (4/3)(pi)r^3; Surface Area = 4(pi)r^2.
What is the volume of a cone (radius r, height h) and its slant height?
Volume = (1/3)(pi)r^2h; slant height l = sqrt(r^2 + h^2); Curved Surface Area = (pi)r l.
State the formula for permutations nPr and combinations nCr.
nPr = n! / (n-r)! (order matters); nCr = n! / [r!(n-r)!] (order does not matter).
What is the basic definition of probability of an event?
Probability = (Number of favorable outcomes) / (Total number of possible outcomes); it lies between 0 and 1.
For mutually exclusive events A and B, what is P(A or B), and what is P(not A)?
P(A or B) = P(A) + P(B) for mutually exclusive events. P(not A) = 1 - P(A).
In Tabular Data Interpretation, what is the first step before answering questions?
Read the table title, row/column headings, and units carefully to understand what each cell represents, then identify exactly which cells the question requires before calculating.
What is the key difference between a bar graph and a line graph in DI?
A bar graph compares discrete categories using bar heights/lengths; a line graph shows trends or change over a continuous variable (usually time) by connecting data points.
In a pie chart, how do you convert a sector's degrees or percentage into an actual value?
Each sector = (its percentage of total) x total value, or (sector degrees / 360) x total value. The whole circle (360 degrees = 100%) represents the total.
What characterizes a Caselet (paragraph) DI question?
Data is given as a descriptive paragraph rather than a chart/table; you must extract the numbers, often build your own table or equations, and then solve.
How do you approach a Missing DI set where some table values are blank?
Use the given totals, ratios, and relationships among rows/columns to set up equations and compute the missing values before answering the questions.
What does a Data Sufficiency question ask, and what are the typical answer options?
It asks whether the given statements are sufficient to answer the question, not the actual answer. Options: (a) statement I alone sufficient, (b) II alone sufficient, (c) either alone, (d) both together needed, (e) both together insufficient.
How do you find the rule in a number series, and what defines an arithmetic vs geometric series?
Look for a pattern in differences, ratios, squares/cubes, or alternating operations. Arithmetic: constant common difference (add/subtract); Geometric: constant common ratio (multiply/divide).
In Quantity Comparison (Quantity I vs Quantity II), what are the standard answer relationships you must determine?
Compute both quantities and choose: Quantity I > Quantity II; Quantity I < Quantity II; Quantity I = Quantity II (or relation cannot be established). The goal is the relation, not exact values.
What this deck covers
The Quantitative Aptitude deck follows the LIC AAO Quantitative Aptitude syllabus — 5 chapters and 27 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 10.0 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 106 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 LIC AAO 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 LIC AAO 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 Quantitative Aptitude cards cover?
They follow the LIC AAO Quantitative Aptitude syllabus — 5 chapters and 27 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.
