Test Your Knowledge includes Questions with answers only. ‘Practice More’ in Section II also include Questions (solved and unsolved) from latest CBSE Exam Papers. All the solutions are standard to the extent that if a student follows the style as adopted in this book for the solution of a question, no examiner can even think of deducting half a mark from the marks allotted to the question. The main stress has been assigned to reasoning everywhere which is the basis of Mathematics.
