Question

Two successive discounts of 20% and 25% are given on the marked price of an article. If the value of discount is equal to Rs. 680, find the Marked price of the article?
1. 1700
2. 1500
3. 1850
4. 1900

Answer 1

Correct Answer - Option 1 : 1700

Given:

Successive discount rate = 20% and 25%

Discounted price = Rs. 680

Formula used:

Effective discount rate = [x + y - (xy/100)]%

Calculation:

Let the Marked price = 100a

Effective discount Rate = [20 + 25 - (500/100)]%

= (45 - 5)% = 40%

Discount Price = (40/100) × 100a = 40a

⇒ 40a = Rs. 680

⇒ a = 680/40 = 17 

Marked price = 100a = 100 × 17 = Rs. 1700

∴ Marked price is Rs.1700
