This book is about the subject of mathematics or quantitative analysis which forms a formidable examination paper in CAT. It deals exhaustively with the type of questions asked through Problems and Solutions format which has been categorized in five sections: The questions most commonly asked in CAT are largely the typical and abstract problems in these sections which are difficult to crack and cannot be solved just through employing basic formulas directly but have to be dealt with analytically. Conforming to the pattern of CAT the book contains around 1200 typical and abstract problems under the aforementioned topics with their innovative solutions. The solutions to the problems will expose. the readers to numerous ways of approaching unusual problems and help in building up the skills to crack them.
