What price should a shopkeeper mark on an article which costs him 880

Let the market price of the article be Rs.x

given that Discount % = 12%

then selling price (S.P) = market  price (M.P) - discount (D)

⇒

⇒ S.P =

⇒ S.P =

⇒ S..P =

he is still gaining profit 

∴ cost price (C.P) =

⇒

⇒

⇒ x = 1250 Rs.

∴ market price of the article is Rs. 1250.

S.P=125*880/100

S.P=1100

M.P=100*1100/88

M.P=1250
