Question
An item is priced 40% above its cost price. It's sold
for Rs. 2268, after applying a discount of x%, and this sale results in a 12% profit. Determine the value of 'x'.Solution
Let the cost price of the article be Rs. a Therefore, 1.12a = 2268 Or, a = 2268/1.12 = 2025 Therefore, marked price of the article = 1.4 × 2025 = Rs. 2835 Therefore, discount percentage = {(2835 – 2268)/2835} × 100 = 20% Hence, option c.
