A trader sells two types of rice at Rs. 24 and Rs. 30 per kg. In what ratio should he mix them to sell at Rs. 29.70 per kg making 10% profit?
A1:1
B1:2
C2:1
D2:3
✓ Correct Answer: B — 1:2
Target CP = 29.7 / 1.1 = 27. Using alligation: (30-27):(27-24) = 3:3 = 1:1... wait. Check math: (30-27)/(27-24) = 3/3 = 1:1. Options might be wrong? Let's check 24x + 30y = 27(x+y) => 3y = 3x => x:y=1:1.
