Question
A shopkeeper purchases rice of two varieties βAβ and
βBβ at Rs. 18 per kg and Rs. 45 per kg respectively. He mixes 1 kg of variety βAβ rice with 2 kg of variety βBβ 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 Γ 2 = Rs. 108 Cost price of 1 kg of the rice mixture = 108 Γ· 3 = Rs. 36 So, profit percentage = (45 β 36) Γ· 36 Γ 100 = 25%
