If goods are purchased for Rs. 450 and one-third is sold at a loss of 10%, at what profit percentage should the remainder be sold to gain 20% on the whole transaction?
A grocer purchased 80 kg of sugar at Rs. 13.50 per kg and mixed it with 120 kg of sugar at Rs. 16 per kg. At what rate should he sell the mixture to gain 16%?
Explanation:
Total Cost = (80 * 13.50) + (120 * 16) = 1080 + 1920 = 3000. Total quantity = 200 kg. Cost Price per kg = 3000 / 200 = 15. Selling Price per kg for 16% gain = 15 * 1.16 = 17.40.
