SSC CGL Tier II level Solution Set 15, Geometry 4

thumb_ssc-cgl-tier-2-solutions-15-geometry-4

This is the 15th solution set of 10 practice problem exercise for SSC CGL Tier II exam and the 4th on topic Geometry. A few of the problems look simple but deceptively so. In the same way, a few of the problems seem to be quite difficult, but can be solved quickly by identifying key geometric patterns and applying corresponding methods that are based on core concepts...

Trigonometry concepts part 3, maxima (or minima) of Trigonometric expressions

thumb_basic and rich trigonometry concepts part 3 maxima trigonometric expressions

Trigonometric functions behave not exactly like common algebraic variables, and so maximizing or minimizing an expression of trigonometric terms requires first conversion of the expression to a single function expression. Frequently the rich algebraic concept of AM GM inequality also comes handy for solving such problems...

SSC CGL Tier II level Solution Set 6, Geometry 3

thumb_SSC CGL Tier2 level solution set 6 geometry3 top

This is the 6th solution set of 10 practice problem exercise for SSC CGL Tier II exam and the 3rd on topic Geometry. 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...
