Geometry Fundas for CAT Quantitative Aptitude Preparation – Part 1

June 18th, 2018 by

I got a lot of feedback via emails and texts that people are looking for a post on geometry. I have been avoiding it for sometime because of two main reasons: a)      It is not one of my strong areas. b)      It takes a lot of time to draw the diagrams that are sometimes required to explain the fundas. The questions on geometry are the trickiest and consumes the maximum amount of time as compared to the questions on other topics in Quantitative aptitude that is why, I have compiled a list of fundas that you might find helpful in solving CAT level questions.

No other question in the CAT is as deceptively simple as Paragraph Completion questions. Superficially, they do not require us to know or remember any rules. They, in fact, require us to do something far more difficult – to think like the writer. Since the last week’s post on Parajumbles, I have been thinking hard over an appropriate parallel to explain the process of solving Paragraph Completion question. And all my thoughts end once again at the same point – Sherlock Holmes. Indeed, picking up the scattered clues, and building them into a clear chain of reasoning for anticipati
