@anif_manzoor hey you buyed these books ...you can see from here the books ...

@ankesu_karak if you don't believe me you can see the index of the books and also see the condition of books not even opened they are absolutely new and all chapters of class 12th are there in books and solutions books also there of all subjects....just the cover of the book is changed as a mentioned it earlier but the content is same ...as well as pw teachers also told that everyyear cover is changed but content is same always so who can't buy new as they are soo expensive don't need to buy new everyyear ....soo if you don't want to buy no worries because I can sell it at 600 rs and people are ready to buy ...i thought you need it that's why I wanted to help you that's why I put soo less price ..
