32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Subject-verb agreement with 'and'
- Two subjects joined by 'and' normally take a plural verb, but when they denote one idea or person, as in 'bread and butter', the verb stays singular.
- Proximity rule in agreement
- With 'either...or' and 'neither...nor', the verb agrees in number and person with the subject nearest to it, not with the first subject.
- Article use with vowel sounds
- Use 'an' before a spoken vowel sound and 'a' before a spoken consonant sound, so 'an hour', 'an MBA', but 'a university' and 'a European'.
- Present perfect with 'since'
- 'Since' marks a starting point and 'for' marks a duration; both pair with the present perfect when the action continues to the present.
- Fixed preposition: comply
- The verb 'comply' is followed by 'with', as in complying with regulations; 'comply to' is incorrect in standard English.
- Relative pronoun choice
- Use 'who' for people, 'which' for things and animals, and 'that' in defining clauses; 'whose' indicates possession for either people or things.
- Position from the right
- In a row of n persons, a person at position p from the left stands at position n minus p plus one from the right.
- Circular arrangement facing centre
- When people face the centre, a person's left is clockwise and right is anticlockwise; when facing outward, both directions reverse.
- Syllogism conversion rules
- 'All A are B' yields 'Some B are A'; 'No A is B' yields 'No B is A'; 'Some A are B' yields 'Some B are A'. Universal statements allow limited conversion.
- Direction after right turn
- A right turn rotates the facing direction 90 degrees clockwise, so a person facing north turns to face east.
- Blood relation tree convention
- Draw males as squares and females as circles, connect spouses horizontally and parents to children vertically, then read the asked relation from the sketch.
- Inequality chain validity
- A definite conclusion needs a consistent chain; a 'greater than' chain joined to a 'less than' relation usually yields no definite conclusion.
- Successive percentage change
- Two successive changes of a percent and b percent produce a net change of a plus b plus ab divided by 100 percent, keeping signs.
- Compound interest formula
- Compound interest equals principal times the quantity one plus rate over 100 raised to time, minus the principal.
- CI minus SI for two years
- For two years, the difference between compound and simple interest equals the principal multiplied by the square of rate divided by 100.
- Average speed equal distances
- When equal distances are covered at speeds x and y, the average speed is twice the product divided by the sum of x and y.
- Train crossing a platform
- Time to cross a platform equals the sum of train length and platform length divided by the train's speed, with units made consistent.
- Boat and stream speeds
- Downstream speed is boat plus stream and upstream is boat minus stream; boat speed is their average and stream speed is half their difference.
- Time and work together
- If A alone finishes in x days and B in y days, working together they finish in xy divided by x plus y days.
- nCr formula
- The number of ways to choose r items from n without regard to order is n factorial divided by r factorial times n minus r factorial.
- IRDAI role and location
- The Insurance Regulatory and Development Authority of India regulates life and general insurance and is headquartered in Hyderabad, Telangana.
- LIC establishment year
- Life Insurance Corporation of India was created in 1956 when the life insurance business was nationalised, with initial capital of five crore rupees.
- Principle of indemnity
- Indemnity restores the insured to the financial position held before the loss, without profit, and applies to general insurance rather than life.
- Insurable interest
- Insurable interest means the policyholder gains from the subject's survival and loses financially from its loss, so the policy is not a wager.
- Utmost good faith
- Both parties must disclose all material facts truthfully; concealment or misrepresentation lets the insurer avoid the contract.
- GIC Re as national reinsurer
- General Insurance Corporation of India is the domestic reinsurer, and the four public general insurers were separated from it in 1972.

- Router versus switch
- A switch forwards frames using MAC addresses within a local network, while a router forwards packets between networks using IP addresses.
- Malware type distinctions
- A virus attaches to files, a worm self-replicates across networks, a Trojan poses as legitimate software, and ransomware encrypts data for ransom.
- Email protocol roles
- SMTP sends outgoing mail, while POP3 downloads mail to one device and IMAP keeps mail synchronised on the server across devices.
