In work life and personal life often we need to learn the basics on a subject quickly. Usually it is not easy to acquire the basic concepts on any subject reliably in a short time from a concise material.

Basic concepts on any subject form the foundation, but generally we have found it is not easy to build it in a short time. Our focus here is on base concepts in a concise form that can be learned quickly and be used as a launch pad for further learning and subject specific problem solving.

Often we added a rich concept layer derived from the base concepts that helps to solve more complex problems with great ease. For us, it is a two layer concept model: Base concepts and Rich concepts derived from base concepts. Objective is efficient problem solving.

How to solve high level circular seating arrangement reasoning puzzles for SBI PO quickly 7

thumb_eight-position-high-level-circular-seating-reasoning-puzzle

In this seventh tutorial session, while solving a high level circular seating reasoning puzzle, we will be giving more time to analysis of all the logic conditions together. With a feel of the nature of the problem then, we will form over logic analysis strategies, select the most promising logic condition to process first...

How to solve Surds part 1, Rationalization

thumb_how-to-solve-surds-part-1-rationalization

Surds are a special group of irrational numbers that can be represented easily in compact form as $\sqrt{2}$, $\sqrt{3}$ etc. In addition, a number of quick math methods in simplifying surd problems make this topic a favored one for testing problem solving abilities in schools and competitive tests...

Basic and rich concepts on Moving Escalator to solve difficult Speed Time and distance problems in a few steps

thumb_escalator time distance problems

Usually time and distance problems involve objects moving on fixed stationary ground base. When the base starts moving, an additional level of complexity is introduced. These are problem areas favorable for applying very basic relative speed concepts and arrive at solution in a few steps...

Basic and Rich Percentage Concepts for solving difficult SSC CGL problems

thumb percentage concepts

In business world, academics, Science and technology, or daily life, use of the concept of Percentage is ubiquitous and all-pervading. Because of its apparent simplicity though, this concept is taken for granted with not much emphasis on its elaboration and explanation....

How to solve hard two row seating reasoning puzzles for SBI PO in confident steps 6

thumb sbi po level two row seating reasoning puzzle in easy steps 6

In this session we have adapted yet again the collapsed column concept to represent the logic table in minimal form while solving a fairly complex two row seating reasoning puzzle of SBI PO level. However, step by step systematic and quick solution could be achieved mainly by strategic analytical approach in selecting and executing right combination of logic statements at the right time...

How to solve high level circular seating reasoning puzzles for SBI PO in confident steps 5

thumb_sbi-po-level-circular-sitting-reasoning-puzzle-in-easy-steps-5-cover.jpg

For solving high level SBI PO type Circular sitting arrangement reasoning puzzles with same ease, in this session we'd adapt the compact logic table representation and strategic logic statement execution methodology we had used in solving family relations, floor stay and other varieties of high level reasoning puzzles in earlier sessions...

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...

How to solve SBI PO level reasoning and logic analysis problems on floors in a few confident steps 4

thumb_SBO PO level efficient reasoning floor stay logic analysis 4 cover

Assignment logic problems form an important class of logic analysis problems that are generally found to be difficult. Collapsed column logic analysis technique and framework removes this inherent difficulty with a structured, systematic and efficient approach. In addition to logic puzzles and family relations problems, this powerful technique helps to solve complex reasoning class of floors problems with ease and efficiency as well...

Basic and rich concepts on Simple interest and Compound interest

thumb_simple interest and compound interest trend  cover

Simple interest for a year is the percentage rate of interest applied on the initial amount invested and it is fixed year to year. On the other hand, Compound interest is the percentage rate of interest applied on the amount available at the beginning of the year, and not at the beginning of the investment period...
