Question
A product is bought at Rs. 4,800 and tagged 25% above
its purchase price. If it is sold after offering a 15% discount followed by a flat reduction of Rs. 84, then determine the profit gained.Solution
ATQ, Marked price of the product = 1.25 × 4,800 = Rs. 6,00 Selling price of product = 6,000 × 0.85 - 84 = 5,100 - 84 = Rs. 5,016 Therefore, profit earned = 5,016 - 4,800 = Rs. 216
