Quantitative Aptitude is the highest-scoring section in SSC, Banking and Railway exams. The five categories below cover every topic that appears in objective papers — from Number System and Arithmetic (the "rank-makers" like Profit & Loss and Time & Work) to Geometry, Algebra, Data Interpretation, Trigonometry and Number Series — each with detailed explanations and 3–4 worked examples.

How to use this section:
  1. Start with Number System & Basics — every later topic depends on it.
  2. Spend the most time on Arithmetic — Profit & Loss and Time & Work alone fetch 4–5 marks per exam.
  3. Memorise the standard formulas in Geometry & Mensuration; the questions are direct.
  4. Practise Data Interpretation sets daily — accuracy improves only with reps.
