Question
2 Kg of sugar at Rs 30 per Kg is mixed with 3 Kg of 2nd
type of sugar to get a mixture costing Rs 46 per Kg. Find the price of the costlier sugarSolution
Let the price of costlier sugar = x Rs. /Kg.  So-net price = 46 = (2 × 30 + 3 × x) / (2 + 3). So (60 + 3x) / 5 = 46 or 60 + 3x = 230 or x = 56.67.
