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.
