I got confused from this 2 links:

which includes SD bala's name with pattabhi ram:https://www.snowwhiteindia.com/book_detail/868/first-lesson-in-strategic-financial-management

 

which has only pattabhi ram's name:https://www.asialawhouse.com/viewarrivals.php?id=1468&tp=o

 

Are the two different books?
