Hi Kalyan,

Cengage books are good to solve math problems if you are preparing for JEE. But before you go for any book, make sure that you complete your textbook problems thoroughly and if you are not a CBSE student, also solve NCERT textbook in advance as these are the basics in which you have to be good at before solving problems from any other books.

Hope this helps.

All the best :)
