A shopkeeper allows a discount of 15% on a text book with the marked price 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?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 23.50.
Successive discounts = (x + y) - (xy/100)
⇒ (10 + 15) - (10 × 15)/100
⇒ 25 - (150/100)
⇒ 25 - 1.5 = 23.5%
Now the total discount is given = D% of MP
Total discount = 23.5% of 100
Total discount = 0.235 × 100 = Rs. 23.5
