For guided learning and practice on Geometry, follow Comprehensive Suresolv Trigonometry Guide with all articles
This SSC CHSL 15th set of 10 questions which is first on Trigonometry, is followed by answers and then the detailed explanatory solutions. For maximum gains, the test should be taken first, and then only the solutions are to be referred to...
You are given 8 identical looking balls with one of the balls slightly heavier than the other 7. You have to identify the heavier ball in 2 weighing attempts. Given is a two-pan balance with no weights. In how many ways can you solve the puzzle is the second harder part of the puzzle...
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...
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…
This is the 80th solution set of 10 practice problem exercise for SSC CGL exam and 8th on topic Geometry. You need to take the corresponding test first before referring to this solution set. Some of the problems need suitable approach for quick solution...
This is the 14th solution set of 10 practice problem exercise for SSC CGL Tier II exam and the 5th on topic Algebra. To solve such problems quickly, identification of inherent patterns and use of associated methods are necessary. The solution set encapsulates the approach...
With initial problem analysis and application of trigonometric expression simplifying and problem solving strategies, the problems chosen in this fourth NCERT trigonometry problem solving session could be solved in a few easy steps. Problem solving approach leads to quick solutions in minimum number of steps...
A simple or compound event (consisting of more than one event) goes on happening systematically at regular intervals till a point just before the end. With each occurrence of the event problem parameters change. The end is reached before the full impact of the event along with the change can happen. This is the boundary to be found out before solving the problem...
This is the 69th solution set of 10 practice problem exercise for SSC CGL exam and 3rd on topic Percentage. Students must complete the corresponding question set in prescribed time first and then only refer to this solution set for extracting maximum benefits from this resource...
This is the 10th solution set of 10 practice problem exercise for SSC CGL Tier II exam and the 1st on topics Time-work, Work-wages and Pipes-cisterns. 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...
