thumb_NSW-HSC-Math-Extension-2-exam-hardest-geometry-question-2018

The problem we'll take up this time was reported in The Sydney Morning Heraldas the hardest one in the Math Extension 2 exam paper in NSW HSW 2018 test in Australia. It was the question 16b on Geometry involving a large number of pairs of similar triangles.

Students not used to identify the key missing element from a host of elements spread all around and think strategically and systematically would find it difficult...

SSC CGL Tier II level Solution Set 14 Algebra 5 video Part 2

This is the second part of the fifth solution set of SSC CGL Tier II algebra. A few of this set of 5 problems are tricky and need application of advanced pattern discovery and concepts and methods for quick solution. Important concepts and techniques used are, pattern discovery, suitable substitution, principle of zero sum of square expressions, denominator simplification, missing element pattern...

SSC CGL level Solution Set 64, Algebra 15

thumb ssc cgl level solution set 64 algebra 15

This is the 64th solution set of 10 practice problem exercise for SSC CGL exam and the 15th on topic Algebra. 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...
