A shopkeeper purchases rice of two varieties ‘A’ and
‘B’ at Rs. 60 per kg and Rs. 30 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 = 60 + 30 × 2 = Rs. 120 Cost price of 1 kg of the rice mixture = 120 ÷ 3 = Rs. 40 So, profit percentage = (45 – 40) ÷ 40 × 100 = 12.5%
