Question
The ratio of the cost price of the Blender and Food Processor is 4:3. The marked price of the Blender is 30% higher than its cost price, while the marked price of the Food Processor is 40% higher than its cost price. The discount provided by the seller on the Blender and Food Processor is p% and q% respectively on their marked prices. If the difference between the selling prices of the Blender and Food Processor is Rs.800 and the difference between the values of p and q is 20%, then find the cost price of the Blender?
Solution
Answer: C CP of Blender = 4b CP of Food Processor = 3b MP of Blender = 4b * 130/100 = 5.2b MP of Food Processor = 3b * 140/100 = 4.2b SP of Blender = 5.2b * (100 - p) / 100 SP of Food Processor = 4.2b * (100 - q) / 100 If q - p = 20 5.2b * (100 - p) / 100 - 4.2b * (100 - q) / 100 = 800 5.2b / 100 (100 - p - 100 + q) = 800 5.2b / 100 * 20 = 800 b = 800*1.04 b = 832 CP of Blender = 4 * 832 = Rs.3328
