A trader purchases 70 Kg of tea at the rate of ₹ 200/Kg and another 30 kg at the rate of ₹ 250/Kg. He pays a sales tax of 4% on the transaction. He mixes both of them and sells the product at the rate of ₹ 240/Kg. What is the percentage gain or loss? (find approximate value)

Price of 1st type tea = 200/kg

Quantity = 70 kg


Amount = 200 x 70


= 14000


Price of 2nd type tea = 250/kg


Quantity = 30 kg


Amount = 250 x 30


= 7500


Total amount = 7500+14000


= 21500


Tax = 4%


Tax amount =


= 860


Net amount for tea = total amount + tax


purchase (CP)


= 21500+860


= 22360


Total quantity for sale = 100 kg


Rate of selling = 240/kg


Total amount of sale (SP) = 240 x 100


= 24000


Overall Profit/Loss = SP– CP


= 24000-22360


Profit = 1640


Profit %




= 7.33%
