Price of Potatoes₁ = 6/- per Kg & the Quantity = 20 Kg => the total cost = Price * Units = 6 * 20 = 120/-

Price of Potatoes₂ = 7/- per Kg & the Quantity = 30 Kg => the total cost = Price * Units = 7 * 30 = 210/-

Total CP = 120 +210 = 330/-

To get 25% Profit, Total SP should be Total CP * (100 + Profit%)/ 100 = 330 * 125/100 = 412.50/-

Total Quantity = 30 + 20 = 50Kg => SP per Kg = 412.50/50 = 8.25/- (Answer)
