Reasoning and Computer Aptitude
Reasoning and Computer Aptitude
This domain checks logical structuring under time pressure and basic digital literacy expected of a bank/NHB officer. Reasoning questions are usually puzzle- and arrangement-heavy, with syllogism, inequality, coding-decoding, blood relations, direction sense and data sufficiency. Computer aptitude covers hardware, operating systems, MS Office, networking, DBMS, internet and cyber hygiene.
Core rules
- In puzzles, fix the most constrained clue first (a definite position, a fixed floor, or a one-to-one mapping) before filling negative information.
- Treat 'only a few A are B' as: some A are B and some A are not B. It does not mean 'no A is B'.
- In inequality chains, combine only same-direction signs; reverse the sign when reversing the statement.
- For computer questions, distinguish RAM (volatile, primary) from ROM (non-volatile), and know that a URL’s domain is resolved by DNS.
Worked example
Statements: All auditors are analysts. Some analysts are clerks. Conclusion: Some auditors are clerks. The first statement gives auditors inside analysts; the second says some analysts (not necessarily auditors) are clerks. The clerk overlap may sit outside the auditor set, so the conclusion does not follow. Answer: conclusion false.
Traps
- Applying 'some' as 'all' in syllogism.
- Ignoring 'either/or' possibilities in puzzles.
- Confusing a web browser with a search engine.
- Losing marks by not checking whether the question asks for 'definitely true' or 'possibility'.
