This book contains the problems followed by solutions of IOQM (Indian Olympiad Qualifier in Mathematics), earlier PRMO (Pre-Regional Mathematics Olympiad) previous years' questions. All the problems are solved by me in the easiest way which AI is not capable of i.e. AI can solve these problems but using advanced mathematics which will not be understood by high school students. So, I hope this book will help students and teachers both in the journey to IOQM.
