Question : A shopkeeper allows a discount of 15% on a textbook with a marked price of Rs. 100. On request, he further allows a discount of 10% on the new price of the goods. What is the overall discount given to the customer?
Option 1: Rs. 23.50
Option 2: Rs. 75.00
Option 3: Rs. 25.00
Option 4: Rs. 76.50
Correct Answer: Rs. 23.50
Solution :
A shopkeeper allows a discount of 15% on a textbook with a marked price of Rs. 100.
Selling price = 100 – 15 = 85
On request, he further allows a discount of 10% on the book's new price.
$\therefore$ New selling price = $85×\frac{90}{100}$ = 76.50
Overall discount = (100 – 76.50) = Rs. 23.50
Hence, the correct answer is Rs. 23.50.
