32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Syllogism validity rule
- A conclusion is valid only if it is true in every possible Venn diagram that satisfies all the given premises. A conclusion true in just one arrangement does not follow.
- Blood relation notation
- Use plus and minus signs or male and female symbols for gender, vertical lines for parent-child links, and horizontal lines for siblings or spouses. Without fixed gender, the relation cannot be determined.
- Direction displacement formula
- After a series of turns, find net north-south and net east-west movement. Shortest distance is the square root of the sum of the squares of those two net components.
- Circular arrangement mirror rule
- Fixing one person's position removes rotation. Clockwise and anticlockwise arrangements of the same set are mirror images, so treat them as different only when the question asks for both.
- Rank from both ends
- Total number of persons in a row equals left rank plus right rank minus one. This holds when the same person is counted from each end.
- Inequality chain conclusion
- In a chain such as A greater than B greater than or equal to C, the combined relation is A greater than C. The strict sign overrides equality when both appear.
- Letter coding shift
- Convert letters to positions A=1 to Z=26, find the constant or alternating shift, then apply it to the target word. Reversal coding maps A to Z and B to Y.
- Analogy relation types
- Check whether the pair links by function, cause and effect, part and whole, degree, or category. Apply the same relation type to the question pair before choosing an option.
- Successive percentage change
- Two successive changes of a percent and b percent give a net change of a plus b plus ab divided by 100. A rise then equal fall always yields a net decrease.
- Compound interest formula
- Amount equals principal times one plus rate divided by 100, raised to the time in years. Compound interest is amount minus principal.
- CI minus SI for two years
- For two years the difference between compound and simple interest equals principal times the square of rate divided by 100. This gives principal quickly when the difference is known.
- Equal gain and loss trap
- Selling two articles at the same price, one at x percent gain and one at x percent loss, always produces a net loss of x squared divided by 10 percent.
- Train crossing platform
- Total distance covered equals train length plus platform length. Time equals that total distance divided by speed, with speed converted to metres per second.
- Boats and streams speeds
- Downstream equals boat plus stream, upstream equals boat minus stream. Boat speed is the average of the two, and stream speed is half their difference.
- Combined work formula
- If A alone takes a days and B alone takes b days, together they finish in ab divided by a plus b days, provided they work at constant rates.
- Alligation ratio rule
- The ratio of two quantities mixed to give a mean price equals the difference between the mean and the cheaper price, compared with the difference between the dearer price and the mean.
- Handshake count formula
- Among n people where each pair shakes hands once, the number of handshakes equals n times n minus one, divided by two. This is the combination of n items taken two at a time.
- Simple interest formula
- Simple interest equals principal times rate times time divided by 100. Interest is charged only on the original principal, not on accumulated interest.
- Subject-verb agreement rule
- A singular subject takes a singular verb. Phrases such as along with, as well as, and together with do not change the number of the subject.
- Since with perfect tense
- Since marks a starting point and takes present perfect or present perfect continuous. For marks duration and can appear with several tenses depending on meaning.
- Article before vowel sound
- Use an before a vowel sound, not merely a vowel letter, so an hour and an MBA. Use a before consonant sounds, including a university and a European.
- Fixed preposition collocations
- Certain verbs and adjectives take set prepositions: comply with, consist of, capable of, deprived of, superior to, married to, and prefer to. These must be learnt as units.
- Parallelism in sentences
- Items joined by and, or, or but must share the same grammatical form. A list mixing infinitives and gerunds is incorrect unless the structure is deliberately varied.
- Reading comprehension trap
- An option can be generally true yet wrong if the passage does not state it. Answer only from information given in the passage, not from outside knowledge.
- RBI establishment facts
- The Reserve Bank of India was established in 1935 and nationalised in 1949. It issues all currency notes except the one-rupee note, which the Government of India issues.
