Answer :
Given info:-
A shop keeper offers a discount of 20% on all the articles at his shop and all makes a profit of 12%.
What is the CP of an article whose MP is Rs. 280 ?
Explanation:-
Given that
The Marked Price of an article (M) = Rs. 280
Discount on it = 20%
Discount (D) = MD/100
⇛ Discount = (280×20)/100
⇛ Discount = 28×2
⇛ Discount =56
Selling Price = Marked Price - Discount
⇛ Selling Price = 280-56
⇛ Selling Price = Rs. 224
Selling Price of the article = 224
Profit on it = 12%
We know that
Cost Price = (100×SP)/(100+g)
⇛ CP = (100×224)/(100+12)
⇛ CP = 22400/112
⇛ CP = 200
Therefore, The CP = Rs. 200
The Cost Price of the article = Rs. 200.
Formula:-
- Discount (D) = MD/100
M = Marked Price
- Selling Price = Marked Price - Discount
- Cost Price = (100×SP)/(100+g)
SP = Selling Price
g = gain or profit
