A man sold an article for ₹390 by first giving a d% discount on its marked price, and
then another discount having the same nominal value (in ₹). If the marked price of the
article is ₹3900, then what is the value of d?
Correct Answer:
A. 45
Explanation:
To find the value of d, we first determine that a d% discount on a ?3,900 marked price is equivalent to 39d. Since the subsequent discount matches this cash value, the total price reduction is 78d. By subtracting this total discount from the original price, we reach the final selling price: 3,900 - 78d = 390. This simplifies to 78d = 3,510, resulting in d = 45.
