How to solve Surds part 3, Surd expression comparison and ranking

thumb_how-to-solve-surds-part-3-surd-expression-comparison-and-ranking

In this third tutorial on how to solve surd problems, we will take up explaining two related problem classes, namely, two-term surd expression comparison and ranking. First we will state and explain two important rich concepts used for quick solution and then apply the rich concepts in solving chosen SSC CGL level problems...

How to solve Surds part 2, double square root surds and surd term factoring

thumb_how-to-solve-surds-part-2-double-square-root-surds

In this second tutorial we will explain how a surd expression under a second square root is dealt with as well as explain two other typical surd problem solving techniques, namely, surd term factoring and coefficient equalization of surd and non-surd terms in a surd equation. We will explain through the process of solving chosen SSC CGL level problems...

Componendo dividendo applied on number system and ratio proportion problems

thumb_componendo-dividendo-in-number-system-ratio-and-proportion

Because of the easy systematic steps most likely we would be able to solve a problem quickly and wholly in mind by Componendo dividendo. In this session we have shown how problems not directly conforming to the Componendo dividendo can still be solved quickly using the concepts of Componendo dividendo...

Componendo dividendo in Algebra

thumb_componendo dividendo in algebra

We have seen Componendo dividendo to simplify competitive math problems in many topics so much so that the problems could usually be solved in mind. In this session we will highlight the power and elegance of the three-step simple process in the area of Algebra with three examples...

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....

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...

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...
