Strategy to prepare the topics of Quant Section asked in SSC CGL Tier-II

From the above table that the syllabus of the quantitative aptitude section is vast. Proper planning and strategy are required to cover these topics and score maximum marks in SSC CGL Tier-II exam. We are going to discuss the topic-wise strategy to prepare each topic.

1. Ratio & Proportion & Percentage: These two topics are very basic and most of the chapters of Quantitative Aptitude are based on these two. If you want to solve Quants questions in a short time then the master key is Ratio Proportion & Percentages. You will find the use of Ratio & Percentages in Data Interpretation, Average, Mixture Allegation, SI & CI, Profit Loss, Partnership etc. First, go through the below study notes then practice some quizzes.

2. Number System, HCF & LCM, Divisibility & Reminder - Number System is a very long and very much conceptual chapter. You need a lot of practice to be a master in this chapter. HCF LCM and  Divisibility Reminder are easy chapters which you can easily learn if you are good in the Number system.

Example: Find HCF (18, 42)?
Solution : Find the prime factors of 18 = 2 * 3 * 3 and 42 = 7 * 2 * 3 and notice the "common" of the two expressions is 2 * 3; So HCF (18, 42) = 6.

Example : LCM (18,42)
Solution : Factors of 18 (2 * 3 * 3) and 42 (7 * 2 * 3). LCM = (2*3*3*7)= 126 (HCF * other factors)
