HCF and LCM

thumb_hcf and lcm

Highest Common Factor or HCF is the largest factor that divides two or more numbers under consideration. It is the largest among all the factors common to the set of numbers under consideration. The LCM is the smallest number that is divisible by the set of given numbers. In other words, LCM is the least common multiple of the set of given numbers...

How to solve Arithmetic mixture problems in a few simple steps 2

thumb_How to solve arithmetic mixing liquids problems in simple steps2

The problems involving Mixture of liquids (and sometimes solids in alloy form) are taught in schools and also form an important part of most of the competitive job tests such as SSC CGL, Bank POs etc. This subtopic belongs to Arithmetic and we have found that students find some difficulties in solving these problems...

Basic and Rich Algebraic Concepts for elegant solutions of SSC CGL problems

thumb_Basic-and-rich-algebraic-concepts

Learning and problem solving in all subjects start with its basic concepts. Rich concepts are derived from this basic concept layer based on problem solving experiences. Use the basic and rich algebra concepts along with powerful problem solving strategies to solve tough problems quickly and surely in a few simple steps...

How to solve difficult Algebra problems in a few simple steps 2

thumb_How to solve algebra problems in a few simple steps 2

Algebra is a discipline of symbol manipulation and usual problems involve only a few basic concepts. But to solve relatively more complex problems in a few simple steps we need to build our rich concept set specific to Algebra as well as use powerful general problem solving strategies and techniques. This is the second offering on Algebra problem simplification...

How to solve difficult Algebra problems in a few simple steps 1

thumb_How to solve algebra problems in a few simple steps 1

Algebra is a discipline of symbolic expression manipulation and usual problems involve only a few basic concepts. Apparently Algebra problems should not be difficult to solve, but it is not always so. When we face such exceptions of problems that are seemingly difficult, problem solving strategies and techniques may still enable solution in a few simple steps...

How to solve Time and Distance problems in a few simple steps 1

thumb_How to solve time and distance problems in a few simple steps 1

Time and distance problems are taught in middle schools and also form an important component in competitive tests. In any case, our endeavor is to solve such problems elegantly in a few simple steps in contrast to generally complex and time consuming conventional approach to solving such problems...

How to solve more Time and Work problems in simpler steps, type 2

thumb_How-to-solve-time-work-problems-in-simpler-steps-type2

In a large number of math problems involving Time & Work, it is stated that certain number of men take certain number of days to complete the work. These problems are usually solved in conventional methods by using per day work rate of 1 man. Instead, the number of days and number of men can be combined into a single powerful measure of work amount, simplifying the process greatly...
