State PSC (e.g. BPSC / UPPSC / MPSC) CSAT, Reasoning and General Mental Ability Flashcards
51 question-and-answer cards covering CSAT, Reasoning and General Mental Ability as it is examined in State PSC (e.g. BPSC / UPPSC / MPSC). 24 of them are printed below, taken from across the deck — no signup, no paywall on the preview.
24 sample cards from the CSAT, Reasoning and General Mental Ability deck
Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.
What are the area and circumference formulas for a circle?
Area = pi x r^2; Circumference = 2 x pi x r; where r is the radius.
What is the area of a triangle given base and height, and Heron's formula?
Area = (1/2) x base x height. Heron's formula: Area = sqrt(s(s-a)(s-b)(s-c)), where s = (a+b+c)/2.
What are the volume and total surface area of a cube and a cuboid?
Cube: Volume = a^3, TSA = 6a^2. Cuboid: Volume = lbh, TSA = 2(lb + bh + hl).
What are the volume and curved surface area of a cylinder and a sphere?
Cylinder: Volume = pi r^2 h, CSA = 2 pi r h. Sphere: Volume = (4/3) pi r^3, Surface area = 4 pi r^2.
State the Pythagoras theorem and the sum of interior angles of a triangle.
Pythagoras: in a right triangle, hypotenuse^2 = base^2 + perpendicular^2. Sum of interior angles of any triangle = 180 degrees.
In syllogisms, what does the statement 'All A are B' allow you to validly conclude?
'All A are B' means every A is inside B. Valid conclusion: 'Some B are A' (converse is particular). You cannot conclude 'All B are A'.
In syllogism logic, what can you conclude from 'No A are B'?
'No A are B' gives valid conclusions 'No B are A' and 'Some B are not A' (and 'Some A are not B'). The negative converse holds fully.
What is the rule about a conclusion drawn from two particular (Some) premises in syllogisms?
Two particular premises ('Some...') yield no definite conclusion. At least one premise must be universal to draw a valid conclusion.
In syllogisms, what is a 'complementary pair' (either-or) conclusion?
When neither of two conclusions individually follows but together they cover all possibilities (e.g., 'Some A are B' and 'Some A are not B' on the same terms), the 'Either...Or' pair is the valid answer.
In blood relations, who is your 'father's brother's son' to you?
Your father's brother's son is your cousin (paternal cousin). The father's brother is your uncle.
In direction sense, if you face North and turn 90 degrees clockwise, which direction do you face? And after a left turn from South?
Facing North + 90 degrees clockwise (right) = East. Facing South + left turn = East. (Clockwise: N to E to S to W.)
In a ranking problem, if a person is 7th from the top and 11th from the bottom, how many people are in the row?
Total = (rank from top) + (rank from bottom) - 1 = 7 + 11 - 1 = 17 people.
In coding-decoding by letter shift, if 'CAT' is coded as 'DBU', what is the rule?
Each letter is shifted forward by 1 position in the alphabet (C->D, A->B, T->U). The rule is +1 letter shift.
What are the alphabet position values of A, J, S, Z (useful for coding-decoding)?
A=1, ... J=10, ... S=19, ... Z=26. Tip: EJOTY (5,10,15,20,25) helps locate positions quickly.
What is the next term in the series 2, 6, 12, 20, 30, ...? Explain the pattern.
Next term is 42. Differences increase by 2 each time (4,6,8,10,12). Equivalently term n = n(n+1): 1x2, 2x3, 3x4...
Identify the type: series 3, 6, 12, 24, 48. What is the next term?
It is a geometric progression with common ratio 2; next term = 96 (each term is doubled).
In seating arrangement, what does 'facing the centre' in a circular arrangement imply about left and right?
When all face the centre, a person's left hand points clockwise direction... actually their immediate left neighbour is in the clockwise direction and right is anticlockwise (mirror of facing outward).
In a linear seating arrangement facing North, where are a person's left and right?
Facing North: left hand points West, right hand points East. So the person to one's right is on the East side.
When reading a Bar Graph, how do you compute the percentage increase between two bars?
Percentage increase = ((later value - earlier value) / earlier value) x 100. Read bar heights against the y-axis scale.
In a Pie Chart, how do you convert a sector's central angle (degrees) into the value it represents?
Value = (sector angle / 360) x total. Conversely, percentage of a sector = (angle / 360) x 100; each 1% = 3.6 degrees.
In a table-based DI question, what is the key first step before calculating?
Identify what each row and column represents and the units, note totals, and read exactly what the question asks (e.g., absolute value vs percentage vs ratio) before computing.
In a Line Graph showing a trend over time, how do you identify the period of maximum increase?
Find the segment between two consecutive points with the steepest upward slope, i.e., the largest positive difference between consecutive values.
What is a 'caselet' in Data Interpretation and how should it be approached?
A caselet presents data in a paragraph (no chart/table). Approach by extracting the numbers into your own table or Venn diagram, then solve as a normal DI set.
In Data Sufficiency, what does it mean when 'Statement I alone is sufficient but Statement II alone is not'?
Statement I by itself gives a unique answer to the question, while Statement II alone does not. You evaluate each statement independently before combining them. The goal is to judge sufficiency, not to compute the final answer.
What this deck covers
The CSAT, Reasoning and General Mental Ability deck follows the State PSC (e.g. BPSC / UPPSC / MPSC) CSAT, Reasoning and General Mental Ability syllabus — 4 chapters and 15 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 12.8 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 126 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.
CSAT, Reasoning and General Mental Ability flashcards FAQ

51 cards. This page previews 24 of them, sampled evenly across the deck so you can judge the difficulty before installing anything.
Are these State PSC (e.g. BPSC / UPPSC / MPSC) 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 CSAT, Reasoning and General Mental Ability cards cover?
They follow the State PSC (e.g. BPSC / UPPSC / MPSC) CSAT, Reasoning and General Mental Ability syllabus — 4 chapters and 15 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.
