Q: Answer-A merchant has two types of sugar. Type A costs 50 per kg, and Type B costs 70 per kg. In what ratio...

ATQ, Let the ratio in which Type A and Type B should be mixed be xy. 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 xy is 1010, which simplifies to 11. So, the two types should be mixed in the ratio 11.
