An article, which is marked ₹ 650, is sold for ₹ 572.

Given in question , marked price = ₹ 650, SP of article = ₹ 572
∴ Discount = marked price - SP of article = 650 – 572 = 78
If the discount be d% then

650 × d	= 78
100

⇒ d =	78 × 100	= 12%
	650

Second method to solve this question :

Using the given formula ,

Discount % =	M.P.− S.P.	×100
	M.P.

Discount % =	650 − 572	×100
	650

Discount % =	7800	= 12%
