[CSAT] - Quantitative Aptitude - Answer Solving Thread

edited January 2014 in CSAT
Guys, the whole idea of this new discussion is to prepare for quantitative aptitude. lets go topic wise and do the basics first.
Members can put questions here. And to explain their points, they can even put the images of the solved answer!
Try avoiding short cuts in the beginning, since there may be non science background members too who might find it difficult to understand the solution.
Lets make it INCLUSIVE ! :P
