ANSWER

Let the cost price of the article be x.

Its is given that selling price is Rs.52 and profit is (x−10) percent.

Therefore,

CP

SP−CP

×100=(x−10)

⇒

x

52−x

×100=(x−10)

⇒100(52−x)=x(x−10)

⇒5200−100x=x

−10x

⇒x

−10x+100x−5200=0

⇒x

+90x−5200=0

⇒(x−40)(x+130)=0

⇒x−40=0,x+130=0

⇒x=40,x=−130

Negative value is neglected and therefore, x=40.

Hence, the cost price of the article is Rs.40
