In competitive exams like SSC, IAS, RAS, UPSC, RRB, etc are asked in Coordinate Geometry questions, which is a core part of the Quantitative Aptitude section, it tests a candidate on concepts in a comprehensive way - geometric shapes. Graphical representation, the distance between digits, section formula, intercept, circle, etc. Generally, if you are expecting to score almost all the marks in the Coordinate Geometry questions, then you must first understand the complexity of these questions. Here you can practice by solving the coordinated geometry questions with the help of the following blogs.
Here you can also practice with other Mock Tests through Test Series.
