Algebra

We have solved an apparently unsolvable problem in this 13th video session on SSC CGL level Algebra problem solving in a few steps. We could find no way to transform the given expression to get the value of the target expression, nor could we evaluate the values of three variables directly from the given expression. As these two main approaches by which most competitive algebra problems are solved failed, we had to resort to a novel method using trial of choice values against target expression for feasibility and then verification of the values thus obtained from the given expression. We have worked backwards. Finally, the solution was quick and satisfactory and it taught us a few new things about how to solve problems. The concepts and methods should prove valuable in addition, for SSC CGL Tier II, CAT or GMAT where algebra is a topic...

In this 11th video session on SSC CGL level Algebra problem solving in a few steps, a specially chosen surd algebra problem is solved to highlight the application of the powerful componendo dividendo method. A conventional solution without use of any advanced concepts is also explained. Both are quick solutions. The concepts and methods should prove valuable in addition for SSC CGL Tier II, CAT or GMAT where algebra is a topic...

In this 9th video on SSC CGL Algebra solving, the chosen problem is solved lightning quick by first dealing with a continued equation and then discovering a special relationship on the input variables. It is again solved using an often used rule of sum of inverses on surd variables nearly as quickly. The second one is a more concept based method on pattern identification and properties of sum of inverses on surd variables. This video should be useful for SSC CGL Tier II, CAT or GMAT as well...

Two selected SSC CGL level algebra problems are solved in a few steps, but this time we could solve each of the problems in more than way using double square root technique, key pattern identification, pattern identification technique and componendo dividendo. The concepts and methods should prove valuable additionally for SSC CGL Tier II, CAT or GMAT where algebra is a topic...
