If the selling price of a chair is 5 times the discount offered, and the discount percentage is equal to the profit percentage then find the ratio of discount offered to the cost price of the chair.1). 6 ∶ 302). 7 ∶ 303). 7 ∶ 354). 6 ∶ 35

Answer»

SINCE SP ? Discount = 5 ? 1

Suppose SP = 5x and discount = x----(1)

⇒ Marked price = 6x

⇒ Discount percentage = [6x – 5x]/6x = 100/6%

Since discount percentage is EQUAL to the profit percentage

⇒ If CP = 6Y then SP = 7Y----(2)

From equation 1 and 2 ?

⇒ SP = 35

⇒ Discount = 7 and CP = 30

∴ Ratio of discount offered to the COST price of the chair = 7 ? 30
