Monkey and the coconuts puzzle with solutions

thumb_monkey-and-the-coconuts-puzzle.jpg

An older version of the monkey and the coconuts puzzle was modified by short story writer Ben Williams and published nearly a century ago. From then on the intriguing puzzle attained the status of one of the most attempted and least solved math puzzles of all time. We will present here easily understandable solutions to both using mathematical reasoning and for the modified version using in addition systematic enumeration…

How to solve a difficult SSC CGL level problem in a few conceptual steps, Trigonometry 8

thumb How to solve SSC CGL level difficult problem in quick conceptual steps trigonometry 8

This problem in contrast to the earlier one looked difficult. The challenge was on - would we be able to achieve its elegant solution? Not always we know about the end in the beginning of our journey, but finally concept based strategic approach provided the initial breakthrough and then led us to the elegant solution in a few more steps...

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...
