Question
2Kg of sugar at Rs 20 per Kg is mixed with 3 Kg of 2nd
type of sugar to get a mixture costing Rs 35 per Kg. Find the price of the costlier sugar ?Solution
Let price of costlier sugar = x Rs./Kg So net price = 35 = (2 
 20 + 3  x) / (2 + 3) So (40 + 3x) / 5 = 35 or 40 + 3x = 175 or x = 135/3 x = 45 Alternate Method :  
So (x - 35) / 15 = 2/3Â So x = 35 + 10 = 45 Rs/Kg
