I purchased this book from Paytm.com at 220rs .In this book they have given important formulae for the major subjects like TOM SOM FM PT .Which may help to clear central government exams.
Its from made easy publications actual cost of the book is 350rs. Definately this book helps for all mechanical engineers. Very handy and given important topics in particular subjects.
Atleast I want to conclude that this book helps to acquire more knowledge in less time.
