Ok so this probably seems easy but I am not sure how to work these. We are given a table with data

Question

Price Paper Price
2010 2 100 2.5
2011 3 125 3
2012 4 150 3.5
we are usig 2011 as base year

a) what is nomial GDP?
b) Real GDP?
c) GDP Price Index
d) CPI

Is nomial just multiplying the 2 numbers?

Price index divide by base year and multiply by 100?

I am not sure how to determine the others.
Thanks for any help?
