Question
A mixture consists of honey and milk in a 1:4 ratio. The
cost ratio of honey to the entire mixture is given as 15:7. What is the ratio of the cost of honey to the cost of milk?Solution
Let the cost of sugar, cost of mixture and cost of milk be 15a, 7a and b respectively. CP of Honey CP of Milk 15a y 7a (7a - b) 8a (7a - b)/ 8a = 1/4 28a – 4b = 8a 20a = 4b a/ b = 1/5 Ratio of cost of honey to that of milk = 15a:b = 15(1): 5 = 3:1
