How to solve SSC CGL level Algebra problem in a few steps 9 video

A single SSC CGL level algebra problem is solved in this video session in three different methods all in quick time. The first approach identified a key pattern and established a relationship between two variables thus avoiding substituting the values of the variables altogether. Result was the quickest solution. In the second solution, a special pattern of sum of inverses is used again for a quick solution while in the third solution direct but efficient surd simplification didn’t need any conceptual maturity. This is a good application of many ways technique. The concepts and methods should prove valuable additionally for SSC CGL Tier II, CAT or GMAT where algebra is a topic...
