You also can solve this hard but finally not so hard problem if you take up analytical reasoning based approach. Surprisingly, knowledge of only elementary geometry is sufficient to solve it...
Find the 10 unique digit number having the special property that the number formed by digits from left to right up to the place for each of the 10 places is divisible by the place number—is a beautiful puzzle presented by John Conway. It is a large and complex puzzle but can be solved using only the basic concepts taught in middle schools…
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…
In a large number of math problems involving Time and Work, when more than one group of workers each comprising of a certain number of members, complete a job taking their own time, and the question is to find time taken by similar groups of workers but with different number of members, worker equivalence method invariably leads to much faster conceptual solution with greatly reduced calculation load...
In this fourth session on reasoning puzzles for Bank PO exams, the puzzle chosen is a floor stay puzzle that has fairly large number of conditions as well as is a three variable reasoning puzzle that is not easy. Majority of the basic and advanced patterns and methods for reasoning puzzle solving needed to be used for quick solution of this well-formed tricky problem...
With initial problem analysis and application of trigonometric expression simplifying and problem solving strategies, the problems chosen in this sixth NCERT trigonometry problem solving session could be solved in a few easy steps. Problem solving approach leads again to quick solutions in minimum number of steps...
