Can any one please tell how to calculate inflation adjusted 10 year average EPS of Nifty.

I have derived the EPS of Nifty by simply dividing Nifty index value by PE (as indicated in the website www.nseindia.com)
Example Today 7th July 2016 Nifty is at 8337.90 and PE is 22.89 , therefore EPS is 8337.90/22.89 = 364.25

Similarly i have calculated EPS of last 10 years on every 31st March 2007......2016

and similarly CPI inflation % of all the 10 years.
current CPI inflation is 5.7%
