Question

A shopkeeper buys an article for ₹ 300. He increases its price by 30% and then gives 10% discount on the new price of the article. Find the amount of discount on the article.

• A. ₹ 35
• B. ₹ 40
• C. ₹ 42
• D. ₹ 39

Answer 1

The correct option is D ₹ 39

Given that,
Cost price of an article = ₹ 300
Increase in price = 30%
$\therefore$ Marked price (M.P) $=\frac{C.P\times (100+percentincrease)}{100}$
$=\frac{300\times (100+30)}{100}$
$=\frac{300\times 130}{100}$
$=\frac{C.P\times (100+percentincrease)}{100}$
= ₹ 390
So, the marked price of an article is ₹ 390.
As, the rate of discount = 10%
$\therefore$ Amount of discount $=\frac{M.P\times rateofdiscount}{100}$
$=\frac{390\times 10}{100}$
= ₹ 39
So, the amount of discount on the article is ₹ 39.
