‘B’ at Rs. 24 per kg and Rs. 18 per kg respectively. He mixes 1 kg of variety ‘A’ rice with 2 kg of variety ‘B’ rice and sells the mixture at Rs. 33 per kg. What is his profit percent?Solution
Cost price of 3 kg of the rice mixture = 24 + 18 × 2 = Rs. 60 Cost price of 1 kg of the rice mixture = 60 ÷ 3 = Rs. 20 So, profit percentage = (33 – 20) ÷ 20 × 100 = 65%
