Question
A merchant has two types of sugar. Type A costs 50 per
kg, and Type B costs 70 per kg. In what ratio should the two types be mixed to get a mixture that costs 60 per kg?Solution
ATQ, Let the ratio in which Type A and Type B should be mixed be x:y. Using the rule of allegation: The cost difference between Type B and the mixture is 70 - 60 = 10. The cost difference between the mixture and Type A is 60 - 50 = 10. Therefore, the ratio x:y is 10:10, which simplifies to 1:1. So, the two types should be mixed in the ratio 1:1.
