This is the first part of the third solution set of SSC CGL Tier II algebra. A few of this set of 5 problems are tricky and posed a bit of a challenge for quick solution. Important concepts and techniques used are, pattern discovery, abstraction, dummy variable substitution, minima of sum of inverses, balanced expression in power of two variables, modified two-factor sum of inverses, inequality analysis, substitution of ratio of two variables, principle of zero sum of square terms, square root concept, and mathematical reasoning.

These are the first 5 questions 1 to 5 and form the 1st part of video on the article * SSC CGL Tier II Solution set 3, Algebra 3* from SureSolv.com.
