Quantitative Aptitude, Verbal reasoning, Analytical reasoning are books written by the Dr.R.S Agarwal under S.Chand piblications.It is one of the book, most arithmetic begginers start with.Actually I bought Quantitative aptitude book for preparation of railway and bank exams from flipkart by going through many positive reviews in the internet.The explanation given by the author was very good and easy to learn and memorise the solutions.
Author had wrote meny shortcut tricks to solve some tricky problems within seconds.Im following this book this book since eight months.
I have attended railway exam recently, half of the aptitude problems given in the question paper are from this book only without changing even values and answers, you believe it or not.
Even though there are many good books from abhijit guha and some other authors, explanation of solution is very good compared to other books.
