This book contains solutions of around thousand questions from the last 15 year question papers of CSIR/UGC NET-JRF Mathematics exam. We have covered eight topics of pure mathematics. We recommend students to first read all the theory related to each subject for better understanding. We have also given some definitions and results which we have used in solving the questions so that students can understand each and every question properly without missing any single detail. Each solution is in a very detailed form. We hope that all the students will get benefit from this book. From the very beginning of this decade, and even in the previous decades also, CSIR/UGC NET-JRF exam has been an important part of our higher education. This exam is now a compulsory prerequisite for getting a job in any college or university. Also from the research point of view, students must have qualified a national level exam for getting admission in any research institute. This book is a platform for the students to clarify all their doubts in any area of pure mathematics. This book covers all questions related to various subjects from last seven-year question papers. These papers almost cover every type of questions which can be asked from a particular topic. Not only NET exam, this will also help students to clear other national level exams and admission tests for Ph.D. in various institutes.
