If the shopkeeper keeps the marked price of an article to Rs. 2500 and says to give two successive discounts of 15% and 20% and still manages to earn a profit of 10%, find the cost price of the article?1). Rs. 1525.452). Rs. 1545.453). Rs. 1595.654). Rs. 1625.45

Answer»

LET the cost price be x

Marked price of article = Rs. 2500

Price after FIRST discount = (85/100) × 2500 = Rs. 2125

Price paid by PURCHASER = (80/100) × 2125 = Rs. 1700

Profit = 10%

⇒ x + (10/100) × x = 1700

⇒ x = Rs. 1545.45

∴ Cost price = Rs. 1545.45
