Question
A man sells a product at a price of ₹120. If he had
sold it at ₹150, his profit would have been 50% more. What is the cost price of the product?Solution
Let the cost price be x. Selling price at ₹120 = x + (profit) Selling price at ₹150 = x + 1.5 × (profit) So, 150 = x + 1.5 × (120 - x) 150 = x + 180 - 1.5x 150 = 180 - 0.5x 0.5x = 30 x = 60 Correct Option: d
