Answer 1

COST PRICE : The price at which a buyer purchases an article is called the cost price(CP) of the article for the buyer.

•SELLING PRICE : The price at which a seller sells an article is called the selling price(SP) of the article for the seller.

•LOSS : If the CP of an article is more than its SP, there is a loss for the seller (CP> SP).

SOLUTION :

GIVEN :

SP of a radio = ₹ 480

Loss = 20 %

CP = (SP × 100) / (100 - loss)

CP = (480 × 100) / (100 - 20)

CP = 48000 / 80

CP = ₹ 600

Answer 2

Answer:

let cp of radio be $x. Then, (100+16)percent of X-(100+16)percent of x=20

= 4 percent of X=20

X=20 x 100/4 = $ 500

Step-by-step explanation:
