Answer:
Total profit = Rs. 720
Step-by-step explanation:
Total Potatos bought P = 120 kg
Rate of Purchase = 24 Rs./kg
∴ Total Purchase amount = 24 × 120 = Rs. 2880
∴ Total Purchase amount Pr = Rs. 2880 ....(1)
He sold 80 kgs with 50% profit.
Selling price for 80 kg = 24 + 24× 50% = Rs36 /kg
∴ Selling price S80 = 36 × 80 = Rs.2880 ....(2)
Remaining potatos = 120 - 80 = 40 kg
40kgs are sold at loss of 25%
∴ Selling price = 24 - 24 × 24% = 24-6 = 18
∴ Selling price for 40 kg = Rs. 18 / kg
∴ Selling price for 40 kg S40 = 40 × 18 =720 rs. ... (3)
From 2 and 3, total selling price S
S = S80 + S40
∴ S = 2880 + 720 = 3600 .... (4)
Total Profit = S - Pr (Profit as Selling price > purchase price)
∴ Total Profit = 3600 - 2880 = 720
∴ Total Profit = Rs. 720
