I got this book for my competition and found that it is a very good book. I was preparing for the Staff Selection Commission but it is more than enough for the exam. All the topics are covered in it. And After reading this I cracked Staff Selection Commission exam. I did well in the exam in reasoning portion. Every topic in this book was given in details which helped me very much in the exam. Every solution is very good and I grasped that very easily.
This book covers almost syllabus of major competitive exams. And there I find sufficient questions to do practice. Solution of every question is error free. It has almost no error. Over all it is good book to crack the reasoning of entrance exam.
