I have searched a lot about books on Olympiad inequalities.. And I have finalized 3 books
1) Secrets in inequalities by pham Kim hung
2) inequalities a problem solving approach by bj Venkatachala
3) Cevtkovski inequalities
Because inequalities is declining recently in Olympiads that's why I cannot do more than 1 book ....
All above mentioned three books satisfy what I want i.e they have almost all important inequalities then solved examples and techniques and then lots of problems with solution...so I am not able to decide which to choose ... Any Suggestions from anyone who has read above books???
Thankyou
In my opinion, the first book is a best between these books.
I need also to say that in the book of Pham Kim Hung with beautiful problems and beautiful solutions there are wrong solutions, but this fact not so disturbs.
The volume 2 you can see here:

The best book, I think, it's the Vasile Cirtoaje's book: "Mathematical Inequalities", 2018, 5 volumes.
