In this 12th video session on SSC CGL level Algebra problem solving in a few steps, two special problems are chosen. The first could be solved in no time by mathematical reasoning and key pattern identification. The second problem is more difficult and we used a special strategy for solving problems involving a series of terms along with mathematical reasoning, key pattern identification and advanced form of sum of inverses property. Finally, 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.
