Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. 1,500.

Selling price = [(Discount)/Marked price] × 100

Or Selling price = [(100 - Discount percent)/100] × Marked price

Now, according to the question

Let the marked price be 100y

[{(100 - 35)/100}y × 100y] + [{(100 - 20)/100} × {(100 - 15)/100} × 100y] = 1995

⇒ 65y + [(80 × 85)/100]y = 1995

⇒ 65y + 68y = 1995

⇒ 133y = 1995

⇒ y = 15

Then,

⇒ 100y = 1500

Hence,

The marked price of the article is Rs. 1500
