‘B’ at Rs. 18 per kg and Rs. 45 per kg respectively. He mixes 1 kg of variety ‘A’ rice with 2 kg of variety ‘B’ rice and sells the mixture at Rs. 45 per kg. What is his profit percent?Solution
Cost price of 3 kg of the rice mixture = 18 + 45 × 2 = Rs. 108 Cost price of 1 kg of the rice mixture = 108 ÷ 3 = Rs. 36 So, profit percentage = (45 – 36) ÷ 36 × 100 = 25%
