In Advanced Problems In Algebra by Vikas Gupta, Is the solutions for Previous year's questions(which are given at the end of each chapter) provided? or do we have to search each and every question in google for their solution
See, if we talk about the Algebra book for JEE Advanced by Vikas Gupta, then most of the questions which have already appeared in the previous years of actual JEE examination do not have their solutions mentioned in the book as you can find them easily anywhere.
So, you'll have to hunt for each and every question yourself. All the best!
