(D) Let the total weight of the groundnut be $100 \ kg$.Total cost $= 100 	imes (20 + 5) = Rs. 2500$.Amount to be received after $20 \%$ profit $= 2500 	imes 1.2 = Rs. 3000$.Since $80 \%$ of the weight of groundnut is left and sold as cattle feed at $Rs. 12.5/kg$,the amount received from the waste $= 100 	imes 0.8 	imes 12.5 = Rs. 1000$.Remaining amount to be received by selling the oil $= 3000 - 1000 = Rs. 2000$.Since the weight of the oil extracted is $20 \%$ of $100 \ kg = 20 \ kg$,the selling price of the oil $= 2000 / 20 = Rs. 100$ per $kg$.
