Question

A shopkeeper makes a 15% profit on a sale. He would have made 18%, if he had sold it for Rs.18 more. The cost price of the article is:

• A. Rs. 650
• B. Rs. 550
• C. Rs. 600
• D. Rs. 500

Answer 1

Answer:

C. Rs. 600

Let the cost price = ₹x

• Selling price at 15% profit = (1.15x)

• Selling price at 18% profit = (1.18x)

Given that the second selling price is ₹18 more:

$1.18x - 1.15x = 18$
$0.03x = 18$
$x = \frac{18}{0.03} = 600$

Cost price of the article = ₹600
