In what ratio should sugar priced at Rs. 84 per kg be blended with sugar priced at Rs. 52 per kg, so that selling the mixture at Rs. 81 per kg yields a profit of 20%?

1. 37 : 31
2. 33 : 31
3. 31 : 29
4. 33 : 37

Correct answer: 33 : 31

Solution

CP of mixture = 75/1.20 = 62.5 per kg. Alligation: (62.5 - 46) : (78 - 62.5) = 16.5 : 15.5 = 33 : 31. So sugar at Rs.78 : sugar at Rs.46 = 33 : 31.
