7. Number System –  Question from this topic comes every year based on some concepts like LCM & HCF, Irrational or Rational Numbers, etc.

 Moderate Level Quantitative Aptitude Topics

These topics require little more effort than the easy topics. Let’s look at each topic one-by-one:

2. Geometry – Geometry is one of the most important chapters that needs to be covered. A major chunk of it occurs in the Quantitative Aptitude section in SSC Exams. One has to have all the theorems and solved problems related to triangle congruence, circle, chords & tangent, etc on their minds.
3. Mensuration – Questions from this section generally include the shapes and their formulas while. One need to remember formulae of Square, Rectangle, Circle, Cone, Cylinder, etc.
4. Trigonometry – The best way to understand  this topic is by mugging up all the Trigonometric Identities and formulas to solve the questions.
