The aim of "200 Challenging Mathematical Word Problems - Practice Set For Grade 9 & Grade 10 Students" book is to help primary school students of Grade 9 & 10 (Class-IX & Class-X) develop their mathematical thinking skills and expand their knowledge of practical real-life applications of basic mathematics taught at Schools. The book provides ample practice on various types of practical mathematical problems.These problems will provide an overall assessment of the student's progress in learning basic mathematical concepts and formulae taught in various Class IX and Class X textbooks. Students will find this book useful in preparing for their examinations and evaluating their knowledge of Mathematics.The problems included in this book are based on the concepts which students learn in the Grade 9, 10 and earlier classes.This book also shares the answers which are provided at the end of this book. Students are encouraged to consciously apply their original thoughts in solving these problems on their own.
