Speed maths and word problems — the backbone of every placement and competitive paper.
Arithmetic aptitude is the scored section of almost every placement paper, bank exam and government recruitment test. The questions are not hard mathematics — they are school-level arithmetic dressed in word problems, and the marks go to whoever reads carefully and works quickly. This section breaks the syllabus into single-idea topics so you can fix one weakness at a time instead of practising everything at once.
Percentage, Ratio and Proportion, Profit and Loss, Time and Work, Time and Distance and Simple and Compound Interest appear in nearly every paper, and most other topics are built on them. Master those six first.
About 45 to 60 seconds in a timed paper. If a question needs longer, mark it and return to it after finishing the ones you can solve quickly.
The core formulas, yes. Anything past that you should be able to derive in a few seconds — for example a train crossing a platform simply means the train covers its own length plus the platform.
The syllabus overlaps almost completely. Bank and SSC papers add Data Interpretation and a few calculation-heavy topics, while campus tests lean towards percentages, ratios, averages and time-speed-work.
