If the profit on selling an article for Rs. 4500 is thrice of the loss on selling it for Rs. 2500. Then the cost price of the article is?
We have,
Selling price = S.P. =Rs.4500
Loss Price = L.P. =Rs.2500
Let the Cost Price C.P.=Rs.x
According to given question,
S.P.−C.P.=3(C.P.−L.P.)
4500−x=3(x−2500)
4500−x=3x−7500
4500+7500=3x+x
12000=4x
x=3000
Then, the cost price is Rs.3000
