Use of the rich ratio technique of multiple of ratio value helps to solve a broad spectrum of ratio problems and specifically many standard number or age ratio problems elegantly in a few steps much faster than conventional procedural methods. The chosen problem here is a tricky one and we will solve it using multiple of ratio value technique as well as conventionally to highlight the power of the rich ratio technique...

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...

How to solve arithmetic boundary condition problems in a few simple steps

thumb_efficient-solution-of-boundary-condition-problems-aritmetic

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...

In 42 days 40 men complete a work. As it happened, instead of all of them working together to finish the job, they started working together, but at the end of every 10th day 5 men left. In how many days would then the work be completed? Rich time and work concept of Mandays technique along with natural number concepts deliver speedy solution...

C and A can do a piece of work in 20 days, B and C in 24 days, and A and B in 30 days. B and C leave after three of them work together for 10 days. In how many more days would A complete the work? Using rich concept of Work rate technique and solving the problem as far as possible in mind, without writing anything on paper, results in within a minute solution...

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...
