This is the second part of the fourth solution set of SSC CGL Tier II algebra. A few of this set of 5 problems need application of advanced pattern discovery and concepts and methods for quick solution. Important concepts and techniques used are, pattern discovery, principle of zero sum of square terms, componendo technique, extra element pattern, roots of a quadratic equation, dummy variable substitution, sum of inverses conversion, abstraction, compact form of cube sum, denominator simplification, and mathematical reasoning.

These are the last 5 questions 6 to 10 and form the 2nd part of video on the article * SSC CGL Tier II Solution set 9, Algebra 4* from SureSolv.com.
