Question
A merchant labeled an item with a price 40% higher than
the cost price and subsequently sold it with a discount of d%, resulting in a 5% profit. Determine the value of 'd'.Solution
ATQ, Let the cost price of the article = Rs. 100 Marked price of the article = 1.40 × 100 = Rs. 140 Selling price of the article = 140 × (100 – d)/100 = 1.05 × 100 140 – 1.4d = 105 1.4d = 35, d = 25 So the value of d = 25%
