Weighted average Qty

Fidzi8 , Expected output is not clear can you explain

Hi amitchandak ,
My output will be: what percentage will change the final price 2021, when I transport the same volume as in 2020.

C2021 - price 2021
C2020C - price 2020
Qty 2020(t) - transported volume 2020

Thank you 
Ondřej
