Question

if an article is sold at loss of 50%. find the cost price in the terms of selling price​

Answer 1

Answer:

Let the percentage of profit or loss on the article be x.

C.P. at x% loss when S.P. is Rs. 50 = Rs.

(100−x)

50×100

C.P. at x% profit when S.P. is Rs. 70 = Rs.

(100+x)

70×100

∴

(100−x)

50×100

=

(100+x)

70×100

⇒5(100+x)=7(100−x)

⇒500+5x=700−7x⇒12x=200

⇒x=
