SSC CGL Tier II level Solution Set 27, Average 1

thumb_SSC-CGL-Tier-II-solution-set-27-average1

This is the 27th solution set of 10 practice problem exercise for SSC CGL Tier II exam and the 1st on Average problems. For maximum gains, the test should be taken first, that is obvious. But more importantly, to absorb the concepts, techniques and deductive reasoning elaborated through these solutions, one must solve many problems in a systematic manner using this conceptual analytical approach. One can learn well only by practicing learning by doing...

Algebraic proof of Least value of sum of reciprocals for any number of positive variables

thumb_principle-of-least-value-of-sum-of-reciprocals.jpg

The result of the least value of sum of reciprocals, used in Algebra represents an important principle of value sharing.

For two positive real variables $a$ and $b$ for example, if $a+b=1$, the least value of sum of reciprocals of $a$ and $b$ will occur when the value of the sum 1 is shared equally between the two variables. This remarkable equal value sharing principle hold true for any number of variables as well as for any positive sum of the variables...

SSC CGL level Solution Set 35 Algebra 10 video Part I

The five problems are not easy but could all be solved quickly enough by pattern discovery and application of suitable techniques. This set of solutions is rich in learning. The solutions and concepts are explained in details. Important concepts used are mathematical reasoning, pattern discovery, strategy of algebraic expression simplification, double componendo dividendo, adapted componendo dividendo, zero valued factoring, and coefficient comparison of like terms. The Concepts and Techniques form the BASIC SKILLSET for solving harder algebra problems EASILY IN MIND...
