Question
A shopkeeper bought an article for Rs. 18,000. He marked
the article x% above the cost price and sold it after two consecutive discounts of 10% and 25%. Find the value of ‘x’ if in this transaction he had a profit of Rs. 468.Solution
Marked price of the article = 18000 × (100 + x)/100 = Rs. ‘18,000 + 180x’
Selling price of the article = Rs. ‘18000 + 468’ = Rs. 18468
Also, Selling price of the article = (18000 + 180x) × 0.75 × 0.90 =
12150 + 121.5x = 18468
121.5x = 6318
x = 52
So the value of x = 52%
