Who is prime minister of australia?

who is our finance minister?

I found this website helpful, As this is having previous year question papers of upsc.
My question is-

1.From where i can find answers of these questions & have a check on my answers ?

2.I also require the analysis of these previous year papers of upsc, which could tell me- how many questions from which chapter. This list is printed in mcgraw hill education book of upsc preparation. 
- But, I dont think- This is correct. 
Do respaper- Provides.... answer sheets along with question papers & analysis of question papers ?
