How to solve Arithmetic problems on Work-Time, Work-Wage and Pipes-Cisterns

thumb_time and work

Different persons or types of persons complete the same work in different number of days as their work capacities are different. For example, a boy may complete a work in 6 days while a man may complete the same work in 3 days. In work-wage problems these work rates become important as the working agents receive wages in ratio of their work capacities. Finally, in pipes and cisterns problems similar working agents come into action in the form of pipes but they receive no wages...

Arithmetic problems on mixing liquids and based on ages

thumb_Arithmetic problems on mixing liquids and ages

When two materials are mixed together in a certain ratio homogeneously, a mixture is formed. Various operations on such a mixture give rise to the topic of Mixture. Usually liquids that can be mixed are used in mixtures. Examples are, Water and milk, Water and fruit juice. Alloys are also formed by mixing metals through specific processes. Grains of same cereal of different price can be mixed giving rise to a grain mixture of another price...

A ratio defines how many times is one quantity with respect to another of same type. It is expressed as a minimized fraction and its numerator is called antecedent and denominator consequent. In practice these terms are not very important...

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...

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...
