7.)

Rs 600

Step-by-step explanation:

Hi,

Let the marked price of an article be 'X'

Shopkeeper allows a discount of 10%,

Selling Price = Marked Price - Discount

= X - 10%X

= X(1 - 1/10)

= 9X/10

Given that shopkeeper gains 20 %,

Gain Percentage = ( Selling Price - Cost Price )/Cost Price * 100

20 = [(9X/10 -450)/450]*100

9X/10 - 450 = 90

9X/10 = 540

X = 600

Hence, the Marked Price of the article is Rs 600.
