Nifty PE is different in valueresearchonline and nse website

Portfolio P/E and P/B Ratio here is different from the nifty P/E and P/B ratio found on NSE site here: https://nseindia.com/content/indices/ind_nifty50.pdf

Difference is quite a big:
P/E is 25 vs 20.65
P/B is 3.29 vs 2.74

Not sure if I am missing something.
Can anyone please confirm which one is correct/latest.

Thank you.

Link to the Valueresearch data?

I am not sure if you can compare the index PE/PB with that of an Index ETF but the NSE website just shows the standalone PE/PB. I think VR takes consolidated numbers into consideration.

Thanks @RahulKhanna
